EXECUTIVE SUMMARY
New Zealand has living practitioners of skills that are currently marginal or declining but become essential under recovery conditions: blacksmithing, hand-tool woodworking, traditional boatbuilding, hand-spinning and weaving, leather tanning, saddlery, coopering, stone masonry, thatching, animal husbandry without modern pharmaceuticals and artificial insemination, manual forestry, food preservation without refrigeration, and traditional Māori skills including harakeke processing, waka building, rongoā Māori, and traditional food systems. Many of these practitioners are elderly. The youngest people with direct experience of pre-mechanised farming, for example, are now in their seventies; the oldest holders of WWII-era making-do knowledge are in their eighties and nineties. The window for capturing their knowledge is finite and closing. Once a practitioner dies, their embodied knowledge — the feel of the metal at forging temperature, the sound of a correctly sharpened tool, the judgment about when a fermenting dough is ready — must be relearned from scratch, a process that takes decades of trial-and-error. No book captures this. No video fully substitutes.
This document outlines: how to systematically identify heritage skills holders across NZ (leveraging the national skills census, Doc #8); documentation methods ranked by fidelity and durability (video, written manuals, structured apprenticeship); priority skills ranked by recovery value; institutional homes for heritage skills programs (polytechnics, marae, museums, community workshops); and the critical distinction between documentation and living practice. Documentation is a backup. Living practice — the transmission of skill from person to person through supervised hands-on learning — is the primary goal. A book about blacksmithing is useful. An elderly blacksmith teaching a young person at a forge is irreplaceable.
The case for action is grounded in demographics, not sentiment. NZ’s age-specific mortality rates (roughly 2–4% per year for people aged 70–79; 8–15% per year for those aged 80+) mean that a fixed pool of heritage skills holders shrinks measurably each year under normal conditions, and may shrink faster under recovery conditions where healthcare access for elderly people with chronic conditions declines (Doc #20). Delay is costly: once a practitioner dies, re-deriving the knowledge they held takes decades of trial-and-error, regardless of investment levels. Identification, documentation, and apprenticeship programs require modest resources relative to their recovery value, and can begin through existing community networks without waiting for formal government direction.

RECOMMENDED ACTIONS
Heritage skills preservation is genuinely time-sensitive because practitioners are elderly and their knowledge is irreplaceable. However, the practitioners are not going to die in Month 1, and recording equipment will remain functional for years. The realistic window for this work is months to years, not days. In Week 1, government bandwidth is consumed by food rationing, emergency powers, and public order — heritage skills identification can begin through community self-organisation and be formalised once the immediate crisis machinery is running.
Months 2–3
Classify heritage skills preservation as a Phase 1 priority. Heritage skills preservation is time-critical knowledge infrastructure. Government direction is needed to ensure resources flow. Fold identification into the national skills census (Doc #8) as it rolls out.
Begin identifying heritage skills holders through existing networks. Use community organisations that already know their members:
- Contact ABANZ (blacksmithing), NZ Spinning and Weaving Society, Traditional Boat Building School, Heritage NZ, Men’s Sheds NZ
- Contact iwi, hapū, and wānanga through Māori liaison channels
- Contact Grey Power and Age Concern to reach elderly people with practical skills
- Ask polytechnic trade instructors to identify their most skilled former students and their own mentors
- Public communication (Doc #2): radio and newspaper appeal for heritage skills holders to register
Deploy video documentation teams. Assemble 5–10 two-person teams (camera operator + interviewer) and assign them to the highest-priority practitioners — oldest first, rarest skills first. Begin recording. Equipment is available now; it will not be available indefinitely.
Identify practitioners willing to take apprentices. Begin matching young people to practitioners. The first placements can begin within weeks — they do not require formal program infrastructure.
First 3 months
Complete initial identification of Tier 1 heritage skills holders. Maintain a national register (integrated with the skills census database) listing each practitioner’s skill, location, age, willingness to teach, and capacity.
Establish Heritage Skills Units at major polytechnic campuses. Each unit needs: a coordinator, workshop space allocation, materials budget, and agreements with local practitioners.
Resource marae-based mātauranga Māori programs. Direct funding and materials to iwi and marae running traditional skills training. Ensure practitioners are compensated.
Begin first cohort of heritage skills apprenticeships. Target: 50–100 apprentices placed with practitioners nationally across all Tier 1 and Tier 2 skills.
Complete video documentation of the oldest and most vulnerable practitioners. For any Tier 1 practitioner aged 80+, video documentation should be completed within 3 months — they may not be available later.
First year
Expand apprenticeship placements to 200–500 nationally. As more practitioners are identified and more apprentices are recruited, the program grows.
Produce first printed heritage skills manuals based on video documentation and practitioner interviews. Distribute to polytechnic libraries, marae, Men’s Sheds, and public libraries.
Integrate heritage skills into the accelerated trade training curriculum (Doc #157). A blacksmithing module within metalworking training. A hand-tool module within carpentry training. A harakeke module within fiber processing training.
Establish heritage skills assessment standards. What does “competent” mean for a heritage blacksmith or a heritage boatbuilder? Developed in consultation with practitioners.
Begin Tier 3 documentation. Lower-priority skills that do not justify full apprenticeship programs but should be documented while practitioners are available.
Years 2–5
First-generation apprentices reaching competence. Some begin taking on their own apprentices — the cascade model activating.
Heritage skills integrated into the regular apprenticeship system (Doc #159). Not a separate program, but a recognised pathway within the national training framework.
Continued documentation. New skills identified, new practitioners found, existing documentation updated based on practical experience.
Regional heritage skills centres developing — specific locations becoming known for particular skills (the Nelson boatbuilding school, the Canterbury forge, the Waikato cooperage) as geographic clusters of expertise emerge.
ECONOMIC JUSTIFICATION
Cost of the heritage skills program
Person-years of direct cost (estimate):
| Component | Person-years (Year 1) | Person-years (Years 2–5) |
|---|---|---|
| Identification and census (integrated with Doc #8) | 5–10 | 1–2 per year |
| Video documentation teams (5–10 teams of 2 people) | 10–20 | 5–10 per year |
| Written documentation and manual production | 5–10 | 5–10 per year |
| Program coordination (regional coordinators) | 5–10 | 5–10 per year |
| Apprentice labour (50–100 apprentices in Year 1, growing) | 50–100 | 100–300 per year |
| Practitioner time (compensated) | 25–50 | 25–50 per year |
| Total | ~100–200 | ~140–380 per year |
Materials cost: Modest. Heritage skills use locally available materials (steel scrap for forging, timber offcuts for woodworking, harakeke for weaving). Workshop space is available through polytechnics and Men’s Sheds. Video equipment exists in current stocks.
Value of heritage skills under recovery conditions
The value is difficult to quantify precisely because it depends on how severely NZ’s industrial supply chains degrade. Under the baseline scenario (grid continues, gradual degradation of imported consumables), heritage skills become progressively more valuable as modern alternatives deplete:
- Blacksmithing: Produces tools, hardware, and agricultural implements without machine shop infrastructure. One competent blacksmith producing tools for a farming community saves an estimated 200–800 person-hours per year of workaround labour with inadequate tools, depending on the community’s size and the range of implements required.1
- Timber boatbuilding: Enables maritime trade (Doc #140, #142). A single functioning trade vessel carrying high-value goods between NZ and Australia could deliver cargo worth thousands of person-hours of domestic production per voyage, against a training cost of 2–5 person-years per competent builder (Doc #141).
- Horse-drawn agriculture: If tractor fuel becomes unavailable for some farms, the alternative to horse-drawn equipment is hand labour. A team of two draft horses with a competent driver replaces an estimated 4–12 hand labourers for ploughing, harrowing, and transport, depending on soil type, field size, and the condition of the implements.2
- Hand-spinning and weaving: NZ produces enough wool to clothe its population many times over, but only if it can be converted to yarn and cloth. Without hand-spinning and weaving capability, wool accumulates as a raw material with no pathway to clothing.
- Harakeke processing: Already covered in Doc #100 — the economic value is the entire domestic rope and cordage supply.
Cost of inaction
The cost of inaction is not measurable in person-years. It is measured in decades of re-learning. If NZ’s last traditional boatbuilder dies without apprentices, timber boatbuilding must be relearned from books — a process that takes years longer and produces inferior results for a generation. If NZ’s last holders of rongoā knowledge die without teaching, that knowledge — accumulated over centuries of observation and practice — must be re-derived through decades of trial-and-error, if it can be recovered at all.
Unlike most recovery investments (where delay increases cost but does not eliminate the option), heritage skills loss creates gaps that persist for decades. The skills can eventually be relearned, but the re-learning period is long enough to span an entire recovery generation.
1. THE PROBLEM: EMBODIED KNOWLEDGE AND MORTALITY
1.1 What embodied knowledge means
A skilled blacksmith does not consult a table to determine forging temperature. They read the colour of the steel — cherry red, bright red, orange, yellow — and know from thousands of hours of practice what each colour means for the workability of the metal under their hammer. They feel the resistance through the hammer handle. They hear the ring of the anvil change as the metal moves. They adjust their technique continuously based on sensory feedback that they could not fully articulate if asked.
This is embodied knowledge — sometimes called tacit knowledge — and it is the defining characteristic of heritage skills.3 It is present in every skilled trade but is most critical in trades where modern instrumentation has not replaced human judgment:
- A hand-tool woodworker reads grain direction by feel and adjusts their plane angle accordingly
- A traditional boatbuilder judges plank shape by eye and experience, not by CNC template
- A hand-spinner controls yarn thickness and twist by the tension they feel in their fingers
- A saddler knows the correct tightness of stitching by how the thread pulls through leather
- A cooper judges the curve of a stave by bending it and feeling the resistance
- A traditional Māori weaver selects harakeke leaves by touch, colour, and growing position, judging fiber quality before extraction begins
The critical point: Embodied knowledge cannot be fully captured in any documentation medium. Written manuals convey procedures but not feel. Video captures motion but not the sensory information the practitioner is processing. The only complete transmission method is direct person-to-person teaching — apprenticeship, in its original meaning. Documentation is valuable as a backup, a supplement, and a starting point for self-teaching when no practitioner is available. But it is not a substitute for living practice.4
1.2 The mortality timeline
New Zealand’s population aged 65 and over was approximately 850,000–900,000 in recent years.5 The subset with heritage skills relevant to recovery is unknown but certainly a small fraction of this total — concentrated among people who grew up on farms, in manual trades, or in communities where traditional practices persisted. Key age cohorts:
Born before 1945 (aged 80+ at time of event):
- Direct experience of WWII-era making-do, rationing, and cottage industry
- May have operated hand-powered farm equipment, horse-drawn implements
- Some will have childhood memories of skills practiced by parents and grandparents that are now extinct in NZ (e.g., hand-operated grain threshing, lime-burning, charcoal production)
- This cohort is very small and shrinking. Life expectancy for NZ men at age 80 is approximately 8–9 years; for women, approximately 10–11 years.6 Under recovery conditions (reduced healthcare, increased stress, possible nutritional decline), these figures may be lower. The practical window for capturing their knowledge is 3–10 years.
Born 1945–1960 (aged 65–80 at time of event):
- Grew up in a less mechanised NZ. Many with farm backgrounds operated equipment and practiced skills that are now automated or abandoned
- More likely to have hands-on experience with manual trades (the generation before CNC, before digital controls, before outsourcing of maintenance)
- Many retired tradespeople in this cohort — machinists, fitters, electricians, mechanics — who trained in an era of broader manual skill
- Practical window for active participation: 5–20 years, but capacity for physically demanding skills (blacksmithing, heavy woodwork) narrows more quickly
Māori knowledge holders — all ages but concentrated in elders:
- Kaumātua and kuia (elders) hold knowledge of traditional practices that may not have been transmitted to younger generations
- Specific skills — rongoā Māori (traditional medicine), waka building, traditional food preservation, advanced harakeke weaving — are held by relatively small numbers of expert practitioners
- Māori life expectancy is approximately 4–7 years lower than non-Māori NZ life expectancy, which narrows the window further7
- Some younger Māori practitioners have learned traditional skills through cultural revitalisation programs, but the depth of knowledge is often concentrated in elders
The arithmetic is simple: If NZ has 200 people over 70 who know how to operate a horse-drawn plough, and approximately 5–10% of them die each year under normal conditions (the NZ age-specific mortality rate for people aged 70–79 is roughly 2–4% per year; for those aged 80+, roughly 8–15% per year8), then in 5 years there are approximately 120–150 left, in 10 years approximately 70–110, and in 15 years approximately 40–80 — scattered across the country, increasingly frail, and harder to locate and engage. The same arithmetic applies to every heritage skill. The numbers are illustrative (the actual count for any specific skill is unknown until the census establishes it), but the trajectory is clear: delay means decades of re-learning what could have been transmitted in months.
1.3 Skills that cannot be learned from books alone
Some practical skills can be reasonably self-taught from good written instructions. Soap-making, for example (Doc #37), follows a repeatable chemical process that a literate person with the right materials can learn from text.
Other skills have a much higher ratio of embodied knowledge to procedural knowledge. These are the skills where heritage preservation is most critical because the gap between documentation and competence is widest:
| Skill | Why it resists documentation | Time to competence from books alone vs. from a teacher |
|---|---|---|
| Blacksmithing | Temperature judgment by colour, hammer control, material feel | Years vs. months |
| Hand-tool woodworking | Grain reading, plane adjustment, tool sharpening “feel” | Years vs. months |
| Hand-spinning | Tension control, fiber drafting, twist judgment — all by touch | Many months vs. weeks |
| Traditional boatbuilding | Plank shaping, fairing by eye, caulking tension | Years vs. 6–12 months |
| Stone masonry | Stone selection, reading cleavage planes, mortar judgment | Years vs. months |
| Saddlery | Leather selection, stitch tension, fit to the animal | Years vs. 6–12 months |
| Horse handling/training | Reading animal behaviour, timing of aids, feel through reins | Cannot be learned from books at all |
| Rongoā Māori | Plant identification in the field, preparation judgment, dosage | Requires extended mentorship |
| Animal husbandry (pre-modern) | Reading animal health without diagnostics, manual procedures | Months to years vs. years |
“Time to competence” estimates are rough and depend on the learner’s aptitude and prior experience. The point is directional: for these skills, person-to-person transmission is qualitatively different from documentation in what it produces.
2. PRIORITY SKILLS FOR HERITAGE PRESERVATION
2.1 Ranking criteria
Skills are prioritised for heritage preservation based on three factors:
- Recovery value: How important is this skill to NZ’s recovery trajectory? A skill that is nice to preserve but not functionally important for recovery ranks lower.
- Endangerment: How few practitioners exist and how rapidly is the knowledge being lost? A skill held by thousands of active practitioners is less urgent than one held by dozens of elderly people.
- Documentation gap: How large is the gap between what written sources capture and what a practitioner knows? A well-documented industrial process with extensive published literature has a smaller gap than an oral-tradition craft.
2.2 Tier 1 — Immediate priority (preservation must begin within weeks)
These skills have high recovery value, very few practitioners, and large documentation gaps:
Blacksmithing and forge work
- Recovery value: High. Blacksmithing produces tools, hardware, fasteners, and agricultural implements using methods less dependent on machine shop infrastructure than precision machining. As machine shop capacity is overwhelmed by demand, blacksmithing fills the gap for simpler metal products (Doc #92).9
- Practitioners in NZ: Perhaps 50–100 who regularly forge, plus several hundred hobbyists. The Artist Blacksmith Association of New Zealand (ABANZ) provides a network but no complete census.10 Virtually all are self-taught or trained overseas — NZ has no formal blacksmithing training program.
- Documentation gap: Large. Published blacksmithing manuals (Weygers, Andrews, Sims) describe procedures but not the judgment that experienced smiths exercise constantly — reading heat colours in different lighting conditions, controlling hammer angle for specific effects, knowing when steel is overworked.
- Infrastructure dependency chain: A working forge requires a fuel source (coal, charcoal from Doc #102, or coke), a forced-air supply (bellows or electric blower), an anvil (100–150 kg of hardened steel — extremely difficult to manufacture; existing anvils must be located and preserved), hammers, tongs, a hardy hole tool set, and a quenching medium (water or oil). NZ has coal (West Coast mines, Waikato) and steel scrap. Anvils are the binding constraint — there is no domestic anvil production, and the existing stock of perhaps 500–2,000 anvils nationwide must be identified and allocated (Doc #8 census).11
- Urgency: High. The most experienced NZ smiths are middle-aged to elderly. Several are nationally recognised craftspeople whose knowledge represents decades of accumulated practice.
Traditional boatbuilding (timber)
- Recovery value: High. Maritime trade (Doc #140, #142) requires a fleet of sailing vessels. NZ’s boatbuilding industry has largely moved to composite (fiberglass) and aluminium construction. Timber boatbuilding skills — lofting, plank shaping, steam bending, caulking, rigging — are concentrated in a small number of older builders.12
- Practitioners in NZ: A few dozen experienced timber boatbuilders, concentrated around Nelson, Auckland, and Bay of Islands. Some are in their seventies and eighties.
- Documentation gap: Moderate. Boatbuilding has extensive published literature (Chapelle, Steward, Bray). But the transition from plans to hull requires spatial judgment, material selection skill, and construction experience that takes years to develop even with good references.
- Infrastructure dependency chain: Timber boatbuilding requires seasoned boat-grade timber (kauri, puriri, pohutukawa, or imported hardwoods from existing stocks), a steam box or kiln for plank bending, caulking materials (oakum or cotton, pitch or modern sealants from existing stocks), copper or bronze fastenings (NZ has no copper smelting; existing fastener stocks are finite), hand tools (planes, adzes, chisels, augers), and a sheltered building space large enough for the hull. Timber supply is adequate from NZ forests but requires 1–3 years of seasoning for green-felled wood, making early timber selection critical.13
- Urgency: High. The most skilled builders are aging out.
Waka building (traditional Māori)
- Recovery value: Moderate to high. Waka (canoes) are relevant to coastal transport and fishing. Waka hourua (double-hulled voyaging canoes) are relevant to inter-regional trade. The skills overlap with but are distinct from European boatbuilding traditions.14
- Practitioners in NZ: Very few. Perhaps 5–15 people with deep knowledge of traditional waka construction techniques. The waka hourua revival, led by builders such as the late Tā Hekenukumai Puhipi Busby (1932–2019), produced some younger practitioners, but the knowledge base remains narrow.15
- Documentation gap: Large. Waka building techniques are transmitted orally and through apprenticeship within iwi. Published documentation is limited and mostly ethnographic rather than instructional.
- Urgency: Very high. Several key knowledge holders are elderly. Loss of even one or two senior practitioners significantly diminishes the knowledge base.
Horse-drawn agriculture and horse handling
- Recovery value: Moderate initially, potentially high by Phase 3–4. If fuel depletion constrains tractor use, horses become the primary draft power for farms (NZ has approximately 70,000–80,000 horses).16 The skills for working with draft horses — harnessing, driving teams, operating horse-drawn implements, farriery, horse training — are not widely held.
- Practitioners in NZ: Perhaps 200–500 people with genuine horse-drawn farming experience — this is an informed estimate, not a counted figure; the actual number is unknown and should be established through the skills census (Doc #8). Likely concentrated among horse-logging operators, Clydesdale breeders, and older farmers in rural areas. A larger group (several thousand) have general horse-handling skills through equestrian sport, but driving a team of heavy horses on a plough is a different skill from recreational riding.
- Documentation gap: Very large for the driving and implement operation; moderate for general horse care.
- Urgency: High. The people who grew up driving horse teams are in their seventies and eighties.
Rongoā Māori (traditional Māori medicine)
- Recovery value: Moderate. Rongoā provides plant-based treatments for common ailments using NZ-native species that are available without importation. It does not substitute for modern medicine (no rongoā treatment replaces antibiotics or surgery) but supplements it, particularly for primary care, pain management, skin conditions, and respiratory illness.17
- Practitioners in NZ: Unknown precisely. Several hundred rongoā practitioners at various levels of expertise, concentrated in iwi and hapū with strong traditional medicine traditions. Some are formally trained through wānanga programs; others learned through oral tradition and apprenticeship.
- Documentation gap: Large. Published rongoā references exist (Riley, Brooker et al.) but practical application — plant identification in the field, preparation methods, dosage judgment — requires mentorship. Intellectual property and cultural sensitivity considerations also apply (see Section 5.3).
- Urgency: High. The most knowledgeable practitioners are often elders.
2.3 Tier 2 — Priority preservation (within first 3 months)
Hand-tool woodworking and timber framing
- Recovery value: High. Hand tools work without electricity. As power tool consumables deplete (sandpaper, saw blades, router bits), hand-tool methods become the default for joinery, furniture, building construction, and repair.18
- Practitioners: A moderate community — perhaps 500–2,000 people with significant hand-tool skills, including hobbyist woodworkers, furniture makers, timber framers, heritage building specialists, and Men’s Shed members. Less endangered than blacksmithing but the highest-skill practitioners are often older.
- Urgency: Moderate-high.
Hand-spinning and weaving (non-Māori traditions)
- Recovery value: Moderate. NZ produces 120,000–140,000 tonnes of wool per year — far more than its population of ~5 million could consume if it can be processed into textiles.19 Converting raw wool to yarn and cloth without industrial spinning and weaving equipment requires hand skills. NZ has a spinning and weaving community, but it is small relative to recovery-era textile demand (Doc #36). An expert hand-spinner produces roughly 100–300 grams of yarn per day; an industrial ring-spinning frame produces hundreds of kilograms per hour. The performance gap is several orders of magnitude, meaning hand-spinning cannot replace industrial production — it fills a niche for essential items (socks, undergarments, rope) while power-loom capacity remains the primary target (Doc #36).
- Practitioners: The NZ Spinning, Weaving and Woolcrafts Society has branches throughout the country. Membership is estimated at several thousand, though many are recreational rather than production-capable spinners.20 The most skilled hand-spinners — those who can produce consistent, strong yarn at useful rates — are a subset, often elderly women.
- Urgency: Moderate. The community is larger than for blacksmithing, but the most expert practitioners are aging.
Harakeke processing (Māori fiber arts)
- Recovery value: High. Harakeke is NZ’s most important domestic fiber (Doc #100). The knowledge for processing it — cultivar selection, harvesting tikanga, muka extraction, fiber preparation — is held by Māori weaving communities.
- Practitioners: Perhaps a few hundred expert kairaranga (weavers) nationally. Te Rōpū Raranga Whatu o Aotearoa (National Māori Weavers Collective) provides the network.21
- Urgency: Moderate-high. Treated in detail in Doc #100.
Leather tanning and saddlery
- Recovery value: Moderate. NZ processes millions of hides per year through industrial tanneries, but the skills for small-scale and manual tanning — and for making leather goods (footwear, harness, belts, bags, equipment cases) by hand — are rare (Doc #36).22
- Practitioners: A very small number of hand-tanners and saddlers. NZ’s industrial tanning sector uses chrome tanning (which requires imported chromium salts); the recovery-era alternative is vegetable tanning using locally available tannins (bark from black wattle, radiata pine, or native tanbark species). Vegetable tanning takes 4–12 weeks per hide compared to 1–2 days for chrome tanning, and produces leather that is stiffer, less heat-resistant, and less uniform — adequate for harness, belts, and heavy footwear but inferior for fine goods.23 Saddlers are rare — NZ has perhaps 20–50 practising hand-saddlers (estimate based on equestrian industry contacts; no census exists), many serving the equestrian and heritage markets.
- Urgency: Moderate-high.
Stone masonry (dry stone and mortar)
- Recovery value: Moderate. Stone is a durable, locally available building material requiring no imported inputs. Dry stone walling is useful for agricultural enclosure; mortar masonry for buildings and infrastructure. NZ has limestone, basalt, schist, and other building stone throughout the country.24
- Practitioners: Very few in NZ. Perhaps 20–50 practising stone masons with traditional skills — this estimate is not sourced from a census and should be verified through Heritage NZ and the NZ Stone Masonry Association if one exists; the actual number may be lower.25 Dry stone walling is more common in Central Otago and Canterbury (heritage stone walls from the pastoral era) but the builders are mostly gone.
- Urgency: Moderate.
Coopering (barrel and cask making)
- Recovery value: Moderate. Wooden barrels and casks are containers for liquids (water, preserves, fermented products) and bulk goods producible from domestic materials. The dependency chain is: air-dried close-grained timber (oak preferred; NZ has some planted English oak but supplies are limited — radiata pine can serve as a substitute for non-spirit vessels with reduced durability), a bending steam box (simple construction, requires heat source), coopering hand tools (jointing plane, croze, howel, chiv — all manufacturable by a blacksmith from Doc #92 or from existing stocks), and metal hoops (mild steel strip from NZ Steel or existing stocks, rolled and riveted — coopering is not self-sufficient from timber alone). Barrels are heavier and less durable than modern plastic or stainless steel containers, and require ongoing maintenance (re-swelling dried staves, replacing hoops), but they can be manufactured and repaired from domestic materials for as long as steel strip and suitable timber are available. A skilled cooper can produce 1–3 barrels per day; a modern factory produces thousands. The skill is nearly extinct in NZ.26
- Practitioners: Perhaps 5–15 people in NZ with genuine coopering skill, associated with the wine and whisky industries (principally cooperages serving Marlborough and Central Otago wineries, and the small NZ whisky distilling sector). The skill is endangered globally.27
- Urgency: Moderate-high due to very few practitioners.
2.4 Tier 3 — Preservation within first 6–12 months
- Thatching: Useful for roofing with locally available NZ materials — raupo (Typha orientalis, abundant in wetlands throughout NZ), harakeke leaves, and tussock (silver tussock and red tussock in the South Island high country). Historical precedent exists in traditional Māori whare construction and early European settler buildings. Very few NZ practitioners. Performance gap: A well-laid raupo or tussock thatch lasts 10–25 years before replacement; corrugated iron (unpainted, under NZ conditions) lasts 40–70 years before it requires replacement or patching. Thatch requires annual inspection and periodic partial re-thatching; iron requires virtually no maintenance until it fails. Thatch also provides better insulation (important under nuclear winter cooling) but is more vulnerable to fire and requires steep roof pitches (40°+) to shed rain effectively — a design constraint for retrofit on existing buildings. Low immediate recovery value (NZ’s corrugated iron roofing stock is adequate for years to decades) but relevant for long-term self-sufficiency as metal roofing corrodes or becomes unavailable.
- Charcoal burning: Traditional charcoal production for fuel and metallurgical use. Some knowledge in forestry communities. Documented in published sources but practical skill improves quality significantly (Doc #102).
- Lime burning: Producing quicklime from limestone for mortar, agriculture, and chemical uses. Historical practice in NZ — lime kilns operated at Oamaru (North Otago), Wairarapa (Martinborough area), Canterbury (Oxford, Amberley), and Golden Bay/Tākaka from the 1860s through the early 1900s. Remnant kiln structures survive at several sites. No current traditional practitioners in NZ. The process is well-documented but practical experience significantly improves yield (controlling kiln temperature at 900–1,000°C) and safety (quicklime is caustic and exothermic when hydrated).
- Manual forestry (crosscut sawing, hand felling): Pre-chainsaw logging techniques. Useful if chainsaw chains and fuel become scarce. Some older forestry workers retain these skills.
- Net making and mending: For fishing nets. Māori kupenga-making techniques and European net-making are both relevant. Small number of practitioners.
- Pottery and brick-making: NZ has suitable clays. Traditional ceramics for storage vessels, building materials, and industrial applications. A small pottery community exists but few work at the scale relevant to recovery production.28
3. IDENTIFICATION OF HERITAGE SKILLS HOLDERS
3.1 Integration with the national skills census (Doc #8)
The most efficient pathway to identifying heritage skills holders is through the national asset and skills census (Doc #8, Doc #156). The census already needs to ask what skills people hold; the heritage skills component adds specific questions targeted at older residents and Māori communities:
Recommended census questions for heritage skills identification:
For all respondents aged 55+:
- Did you grow up on a farm? If so, what equipment and methods did you use that are no longer common? (Open-ended — capturing specifics like “drove a horse team,” “operated a cream separator by hand,” “made soap at home”)
- Do you have experience with any of the following? [Checklist of priority heritage skills]
- Can you teach these skills to others? Are you willing to?
- Do you have tools or equipment related to these skills? (Identifying heritage tools is almost as important as identifying practitioners — a complete set of coopering tools or a working forge represents physical infrastructure that cannot be easily replicated)
For Māori respondents (delivered through iwi and marae channels — see Section 5):
- Do you hold knowledge of traditional skills (weaving, rongoā, waka building, food preparation, navigation, cultivation)? At what level?
- Are you willing to teach?
- Who else in your whānau, hapū, or iwi holds traditional knowledge?
3.2 Community-based identification
The census will miss people. Community-based networks are essential supplements:
Existing organisations that can identify heritage skills holders:
| Organisation | Skills they can identify | Coverage |
|---|---|---|
| Te Rōpū Raranga Whatu o Aotearoa (National Māori Weavers Collective) | Harakeke processing, weaving | National |
| Artist Blacksmith Association of NZ (ABANZ) | Blacksmithing | National |
| NZ Spinning, Weaving and Woolcrafts Society | Hand-spinning, weaving, dyeing | National (branches in most regions) |
| Men’s Sheds NZ | Various workshop skills, often held by retired tradespeople | Approximately 100+ sheds nationwide29 |
| Heritage New Zealand Pouhere Taonga | Heritage building trades, stone masonry | National |
| Classic Boat Association of NZ / Traditional Boat Building School | Timber boatbuilding | Auckland, Nelson, Bay of Islands |
| Grey Power NZ / Age Concern NZ | General access to elderly population | National |
| Federated Farmers / Rural support networks | Agricultural heritage skills | Rural NZ |
| Iwi, hapū, and marae networks | All Māori traditional skills | Regional/local |
| Wānanga (Te Wānanga o Aotearoa, Te Wānanga o Raukawa, Te Whare Wānanga o Awanuiārangi) | Mātauranga Māori — rongoā, weaving, waka, navigation | National |
| NZ Farriers Association | Farriery (horseshoeing) | National |
| Museum networks (Te Papa, regional museums) | Identify former staff and volunteers with heritage skills knowledge | National |
| Vintage machinery clubs and heritage farming groups | Pre-mechanisation agricultural skills | Regional |
3.3 The geographic problem
Heritage skills holders are not uniformly distributed. Rural areas — particularly those with strong farming, forestry, or maritime traditions — are likely to have higher concentrations. Māori knowledge holders are concentrated in areas with strong iwi and marae presence. Specific regional concentrations include:
- Northland and East Cape: Strong Māori traditional knowledge. Harakeke, waka, rongoā.
- Central Otago and Canterbury: Dry stone walling heritage. High-country farming traditions.
- West Coast (South Island): Manual forestry, gold-mining heritage skills, bush craft.
- Nelson and Marlborough: Timber boatbuilding community. Maritime heritage.
- Waikato and Bay of Plenty: Agricultural heritage. Some blacksmithing. Strong Māori knowledge communities.
- Southland: Remote farming skills, horse handling, self-sufficiency traditions.
- Chatham Islands and Stewart Island: Remote community self-sufficiency skills.
Regional identification teams should include people with local knowledge of their communities — the local Rural Support Trust coordinator, the marae chairperson, the secretary of the local Men’s Shed — because they know who in their community has skills that a national census might miss.
4. DOCUMENTATION METHODS
4.1 The hierarchy of documentation fidelity
Documentation methods are ranked here from highest to lowest fidelity — how completely they capture what the practitioner knows:
1. Structured apprenticeship (highest fidelity) A young person works alongside the practitioner for months or years, learning by doing under direct supervision. The apprentice absorbs embodied knowledge — the feel, the judgment, the timing — that cannot be captured in any recording medium. This is the gold standard and should be the primary method wherever practitioners are willing and able.
2. Video documentation with practitioner narration High-definition video of the practitioner working, with their own narration explaining what they are doing and why. Multiple camera angles. Close-ups of hand positions, tool angles, material behaviour. The practitioner is encouraged to explain their decision-making: “I’m watching the colour of the steel — see how it’s going from dark cherry to bright cherry? That’s when I know it’s ready to work.” Video cannot transmit feel, but it captures the visual and auditory information that a book cannot.
3. Structured interview with demonstration A skilled interviewer (ideally someone with basic knowledge of the craft) asks the practitioner to demonstrate key processes while answering detailed questions: “How do you know when it’s right? What mistakes do beginners make? What would you do differently if the material were [variation]?” This produces both video and a detailed written transcript.
4. Written manual produced with practitioner input A technical writer works with the practitioner to produce a step-by-step manual, with the practitioner reviewing and correcting each draft. The manual includes photographs, diagrams, and the practitioner’s own tips and warnings. Better than a manual written by someone who has only read about the skill, because the practitioner catches errors and fills in gaps.
5. Written manual from published sources (lowest fidelity) A manual compiled from books, historical sources, and general technical knowledge without practitioner input. Useful as a backup and for skills where no practitioner is available, but the most likely to contain errors and omit critical tacit knowledge.
4.2 Video documentation protocols
Video documentation should begin immediately for the highest-priority skills and oldest practitioners, because it requires equipment that is currently available and functional but will progressively degrade.
Equipment requirements:
- Digital video camera (multiple — at least two for different angles). Currently abundant in NZ. Any modern smartphone produces adequate video. Dedicated cameras produce better results.
- External microphone (clip-on or directional) — critical for capturing narration clearly in noisy workshop environments (hammer on anvil, saw on wood)
- Tripod(s) for stable footage
- Adequate lighting (workshop environments are often poorly lit)
- Storage media (SD cards, hard drives). Currently abundant in NZ retail and institutional stocks. Note: digital storage is a depreciating asset — SD cards have finite write cycles (typically 10,000–100,000 depending on type) and hard drives have mechanical lifespans of 3–7 years under regular use. All video should be backed up to multiple media and, for the highest-priority recordings, transcribed to print (see Section 4.4). NZ’s continued grid power (85%+ renewable hydro and geothermal) means digital playback equipment remains functional longer than in jurisdictions dependent on fossil-fuel generation, extending the useful life of video archives.
Recording protocol:
- Introduce the practitioner and the skill. Record their name, location, age, and how they learned the skill (who taught them, when, where).
- Record a complete demonstration of a representative process from start to finish — uncut, at real speed. A blacksmith making a simple tool. A weaver processing a leaf to finished muka. A boatbuilder fitting a plank.
- Record the same process again with detailed narration and pauses for explanation. Encourage the practitioner to verbalise their decision-making.
- Record close-ups of critical moments — the details that make the difference between success and failure.
- Record a “mistakes and corrections” segment — the practitioner deliberately demonstrates common errors and how to recognise and correct them.
- Interview the practitioner about the skill in broader context: what tools are essential, what materials work best and why, what they wish someone had told them when they were learning, what aspects cannot be learned from watching and must be learned by doing.
Total recording time per practitioner: Plan for 4–12 hours of raw footage per skill area per practitioner, depending on the complexity of the skill. A blacksmith demonstrating the production of a basic tool set might require 8–12 hours; a spinner demonstrating fiber preparation and yarn production might require 4–6 hours.
4.3 The equipment window
A critical urgency factor for video documentation is that the recording equipment itself is a depleting asset. Digital cameras, smartphones, and storage media rely on electronics that NZ cannot manufacture. Batteries degrade. Screens fail. SD cards have finite write cycles. The ability to produce high-quality video documentation exists now, in Phase 1, but will progressively diminish.
Assessment: Video documentation capacity is likely available for 3–10 years, depending on equipment maintenance, battery replacement from existing stocks, and the rate at which cameras and storage media are damaged or fail. The lower bound (3 years) assumes rough handling, no systematic maintenance, and early battery depletion; the upper bound (10 years) assumes careful management, centralised equipment pools, and NZ’s continued grid power enabling regular recharging. After that window, NZ may still have some functional cameras and screens, but the reliability and availability will be much lower. This means:
- The highest-priority video documentation (Tier 1 skills, oldest practitioners) should happen in the first 3–6 months
- Tier 2 documentation in the first 12 months
- All documentation intended to rely on video should be completed within the first 2–3 years to be safe
This does not mean documentation stops after 3 years — written documentation, apprenticeship, and whatever recording capability remains continue indefinitely. But the window for high-quality, comprehensive video documentation is finite.
4.4 Print-based documentation
All video documentation should be supported by printed materials for long-term preservation. Video is high-fidelity but fragile (depends on functioning electronics). Print is lower-fidelity but durable.
Documentation format for each skill:
- A printed manual (A4, illustrated) covering the complete process from materials selection through finished product
- Step-by-step photographs extracted from video, printed at sufficient size to show detail
- Annotated diagrams of tool positions, material orientations, and critical angles
- A “troubleshooting” section derived from practitioner interviews: common problems and their solutions
- Materials list: what tools are needed, what materials, what substitutes exist
- A “practitioner’s notes” section: the practitioner’s own words about the skill, transcribed from interview
Print runs should be sufficient for distribution to all polytechnic libraries, relevant marae, major public libraries, and the National Library. The Recovery Library’s printing infrastructure (Doc #29, #30) applies here.
4.5 Mātauranga Māori: partnership framework and documentation protocols
4.5.1 Why partnership is the operating model
The default mode of institutional engagement with indigenous knowledge — in NZ and internationally — has historically been extractive: identify useful knowledge, document it, and incorporate it into government or academic programmes with minimal ongoing engagement with the source communities. The Crown’s relationship with mātauranga Māori has included periods of active suppression (the Tohunga Suppression Act 1907, which prohibited Māori healers from practising and was not repealed until 1962) and periods of academic extraction (documenting Māori knowledge in European frameworks without community control).30 This approach fails for three reasons:
Practical: Knowledge holders will not cooperate with extractive programmes. Māori communities have well-founded historical reasons for distrusting Crown approaches to their knowledge and resources. A programme perceived as extractive will be resisted, and the knowledge will remain inaccessible. This is the consistent experience of government and academic programmes that have attempted to document mātauranga Māori without community partnership.31
Quality: Embodied knowledge (Section 1.1 above) cannot be fully captured through documentation alone. The judgment that an experienced kairaranga brings to cultivar selection, the diagnostic skill a tohunga rongoā applies to plant identification — these require ongoing teaching relationships. Extracting the information and walking away produces a degraded copy.
Sustainability: A partnership model creates an ongoing institution — the knowledge community continues to develop, adapt, and teach. An extraction model produces a static document that degrades over time as conditions change and no one updates it.
4.5.2 What partnership means in practice
Governance: Māori knowledge holders have decision-making authority over how their knowledge is documented, taught, and applied. The Mātauranga Māori Recovery Council (Section 4.6 below) provides the governance mechanism. Government provides resources and coordination; the Council directs how mātauranga is integrated.
Tikanga (protocol): Cultural protocols around knowledge — who can learn it, when and where it is taught, what spiritual or ceremonial dimensions accompany it — are respected. In many cases they encode practical wisdom: the tikanga of not cutting the rito (central shoot) of harakeke is both culturally mandated and agronomically optimal.
Intellectual property: Documentation of mātauranga Māori belongs to the source community (iwi, hapū, or whānau). The Wai 262 report (Ko Aotearoa Tēnei) from the Waitangi Tribunal established the principle that Māori have legitimate interests in controlling how their traditional knowledge is used.32 Recovery-era documentation should follow this principle — recordings and written materials are held by the originating community, with copies available for Recovery Library use only with community consent.
Compensation: Practitioners who teach are compensated at rates equivalent to other specialist instructors. Māori communities that contribute knowledge, cultivars, and teaching should share in the benefits of programmes built on their knowledge — not only in terms of access to products but in the economic and social structure of the resulting industries.
Autonomy: Māori communities decide the pace and extent of their participation. A tohunga rongoā who is willing to teach some aspects of their practice but not others is respected. An iwi that wants to develop kaitiakitanga-based resource management within its own rohe, on its own terms, is supported.
4.5.3 Practical limits of partnership
Partnership does not mean that mātauranga Māori programmes are exempt from practical assessment of efficacy. If a traditional practice is recommended, the recommendation should be based on evidence of practical efficacy. If a traditional preparation is proposed for medical use, it should be subject to safety assessment — documented traditional use, practitioner expertise, and observed outcomes (see Section 4.7 below for the quality assurance framework).
The urgency is real: knowledge holders are aging, synthetic stocks are depleting, and capability gaps are opening. The Council must balance cultural protocols with practical timelines. In most cases this is not a conflict — cultural protocols facilitate effective knowledge transmission. Where genuine conflicts arise, they should be resolved through negotiation within the Council.
4.5.4 Documentation protocols
Documentation of mātauranga Māori requires specific protocols that differ from the general approach in Sections 4.1–4.4:
- Māori ownership of documentation: Video, written materials, and other records of traditional Māori knowledge belong to the iwi, hapū, or whānau from which the knowledge originates. They are not government property and should not be placed in government archives without explicit permission and agreement.33
- Māori-led recording: Māori practitioners should be interviewed and recorded by Māori documentarians. The interview should be conducted in a culturally appropriate setting (often at a marae or on the land where the practice occurs) and may include karakia and other cultural elements.
- Te reo Māori: Recordings should be in whatever language the practitioner is most comfortable with — often a mix of te reo Māori and English. Full transcription should preserve the original language.
- Consent and benefit-sharing: Practitioners must give informed consent that addresses how the documentation will be used, who will have access, and what benefits flow back to the knowledge-holding community.
4.5.5 AI inference capability for Māori communities
Doc #129 describes a hub-and-spoke architecture for AI inference, in which a central hub produces distilled domain-specific models that are loaded onto compact spoke devices and shipped to partner locations. Māori communities should receive spoke devices as a priority deployment — not as recipients of centrally produced outputs, but as independent operators with their own inference capability.
The practical case: Māori knowledge holders working with a locally deployed spoke device can generate documentation, training materials, and adapted guidance in te reo Māori, at their own pace, under their own direction. A tohunga rongoā working with a spoke loaded with a pharmacological reference model can cross-reference traditional preparations against known phytochemistry without sending their knowledge to a central facility. An iwi environmental management unit can model fisheries recovery, pest control strategies, or planting schedules using local data without depending on government intermediaries.
Spoke devices should be deployed to major wānanga (Te Wānanga o Raukawa, Te Wānanga o Aotearoa, Te Whare Wānanga o Awanuiārangi) and to iwi centres with active mātauranga programmes. The spoke architecture inherently supports this: each device operates independently once loaded, requires only grid power (which NZ maintains), and can be refreshed with updated models when a hub connection is available. The cost is the hardware and the initial model preparation — modest relative to the value of enabling Māori-led knowledge production.
This is a capacity investment: Māori communities with inference capability can produce their own adapted documentation for their own communities, in their own language, under their own governance. It converts the AI facility from a service provider into a capability that Māori communities operate themselves.
4.5.6 Separated library sections under iwi governance
The Recovery Library’s physical distribution network (Doc #168, #169) should include dedicated sections for mātauranga Māori content at every regional library, with governance over those sections held by the originating iwi or hapū.
In practice:
- Marae-held originals: The primary copies of all mātauranga Māori documentation — video, written manuals, practitioner recordings — are held at the marae or iwi centre of the originating community. These are not government property.
- Regional library sections: Regional Recovery Libraries hold copies of mātauranga content in a dedicated section, physically distinct from general technical documentation. Access and lending policies for this section are set by the originating community through the Mātauranga Māori Recovery Council (Section 4.6 below).
- Clear attribution: Every document in the mātauranga section identifies its iwi, hapū, or whānau origin and the terms under which it has been made available.
- Withdrawal rights: If an originating community decides to restrict or withdraw a document, the regional library complies. This should be codified in the library’s founding charter as a core operating principle.
This structure ensures that Māori knowledge in the Recovery Library system is visibly Māori-owned, not absorbed into a general collection where its provenance is obscured.
4.6 Mātauranga Māori Recovery Council
The institutional mechanism for coordinating Māori heritage skills across the Recovery Library is a national Mātauranga Māori Recovery Council, drawn from wānanga, the National Māori Weavers Collective, rongoā practitioners’ networks, iwi authorities, and relevant Crown agencies. The Council is Māori-chaired, with authority over how traditional knowledge is documented, taught, and deployed.
This structure should be established in Months 6–12, once initial crisis management is settled. Building it properly — with genuine Māori governance — takes time. Iwi networks function without it in the early months; the Council’s value is in scaling and coordination across the library’s technical programmes.

└── Documentation and Heritage Preservation
└── Integrated with this document's heritage skills programme
└── Māori-led recording teams
The Council’s secretariat requires approximately 3–5 person-years in Year 1, declining to 2–3 per year thereafter. Its primary function is coordination: ensuring that mātauranga Māori training programmes are resourced, that practitioner compensation is consistent, and that the documentation protocols in Section 4.5.4 are followed across all programme areas.
4.7 Quality assurance for mātauranga-derived practices
Quality assurance for practices derived from mātauranga Māori must distinguish between categories:
For practices with measurable physical outcomes (e.g., harakeke rope strength, rongoā treatment of wounds): Assess using the same methods as for any other recovery-era practice. Harakeke rope is destructively tested regardless of whether it was processed using traditional or mechanical methods. Rongoā preparations for wound care are assessed by clinical outcome — does the wound heal? Is there evidence of adverse reaction?
For practices with less directly measurable outcomes (e.g., kaitiakitanga resource management, maramataka planting calendars): Assess pragmatically through comparative observation. If fish stocks managed under rāhui are maintained while stocks elsewhere decline, the practice is working. If crops planted according to maramataka timing perform comparably to or better than crops planted by other calendars, the practice has value. Comparative assessment is appropriate; pre-emptive dismissal is not.
For practices with primarily social or psychological value (e.g., karakia before harvesting, wairua-based healing): These serve genuine functions in community cohesion, cultural continuity, and psychological wellbeing — all of which matter for recovery (Doc #122). They should not be assessed for physical efficacy because that is not their purpose. Practitioners who wish to incorporate karakia or other cultural practices into their teaching and fieldwork should be free to do so. No separate resource allocation is required — they integrate naturally into existing programme activities.
4.8 The case for open sharing
Under normal conditions, restricting access to valuable knowledge is routine and rational — companies protect trade secrets, tradespeople guard competitive advantages, researchers hold unpublished findings, communities maintain cultural protocols around traditional knowledge. These are ordinary features of a functioning economy, not pathologies. Under recovery conditions, many of these restrictions carry costs that the country may not be able to afford, and the recovery system should make a clear and sustained case for sharing. This argument extends well beyond heritage skills — it applies across the entire economy — but it is raised here because the heritage skills programme brings it into sharp focus.
Within the heritage skills programme specifically, this applies to blacksmiths, woodworkers, weavers, herbalists, boat-builders, machinists, and other practitioners whose skills are scarce precisely because few others know them. Sharing freely creates more practitioners but also more competition for their labour. Withholding keeps them indispensable. Both responses are rational, and the same logic applies to farmers with hard-won soil knowledge, tradespeople with specialised repair techniques, and communities with traditional practices governed by cultural protocols about who may access them.
The argument for sharing is the same in every case: knowledge is the most valuable resource per unit of effort under recovery conditions, and the marginal cost of sharing documented knowledge is near zero. A water treatment technique that prevents dysentery benefits every community that learns it. A machining procedure that extends bearing life benefits every workshop that adopts it. A crop rotation adapted to nuclear winter conditions benefits every farm that tries it. Restricting access to knowledge that could prevent illness, crop failure, or infrastructure collapse imposes real costs on real people.
The Recovery Library cannot compel sharing and should not attempt to — knowledge holders who feel coerced share less, not more. But the Library should be clear about the stakes: knowledge that is withheld when it could have saved lives or prevented suffering represents a cost borne by the people who needed it. Every knowledge holder should understand this when deciding what to share.
Most will share willingly, because the situation demands it and because skilled people generally want their knowledge to survive. That goodwill is the programme’s most important asset and should not be undermined by building an elaborate incentive structure that implies people need to be paid to do the right thing. At the same time, the recovery system should reciprocate naturally: knowledge holders who contribute are contributing something of genuine value, and the recovery economy should reflect that through priority access to materials they need for their craft, apprentice labour directed to their own projects, and recognition of their role in recovery governance. This is not a formal exchange — it is how a functioning community treats people who contribute to it.
A note on emergency powers and documented knowledge. Knowledge that exists only in a person’s head cannot be compelled — no emergency power can force someone to teach what they know. But once knowledge has been documented onto a physical medium — a printed manual, a hard drive, a set of engineering drawings in a company safe — it becomes property, and property can be requisitioned under the same emergency powers framework (Doc #144) that applies to warehouses, vehicles, and industrial equipment. This applies to a manufacturer’s proprietary process documentation as much as to a community’s traditional knowledge recordings or a university’s unpublished research data.
In almost all foreseeable circumstances, requisitioning documented knowledge would be counterproductive. The immediate gain — access to one piece of information — would be outweighed by the destruction of trust with every other knowledge holder watching. A government that seizes a company’s trade secrets will find that other companies destroy theirs. A government that requisitions documented traditional knowledge will find that practitioners stop documenting. The practical case for respecting ownership is strong precisely because the alternative is self-defeating.
But if people are starving and a documented technique could prevent it, then ownership rights over recorded knowledge, like most property rights, become subject to the same emergency calculus that applies to every other form of property under the CDEM Act. The appropriate framing is not “this can never happen” but “the threshold should be at least as high as for any other requisition, the costs are likely higher, and in practice there is almost always a better path — persuasion, reciprocity, negotiation — that preserves the relationship and keeps knowledge flowing voluntarily.”
5. INSTITUTIONAL HOMES FOR HERITAGE SKILLS PROGRAMS
5.1 Polytechnics
NZ’s polytechnic network (see Doc #157 for detailed treatment of accelerated trade training infrastructure) has the physical infrastructure — workshops, tools, classroom space — to host heritage skills training programs. Key advantages:
- Workshop facilities already exist (machining, woodwork, welding, construction)
- Administrative infrastructure for enrolling students, tracking attendance, issuing credentials
- Distributed nationally — at least one major campus in each region
Recommended approach: Each polytechnic campus establishes a Heritage Skills Unit within its existing trade training structure. The unit:
- Provides workshop space and tools for heritage skills practitioners to teach
- Handles logistics (scheduling, materials supply, student enrollment)
- Ensures practitioners are compensated and supported (housing if needed, food, transport)
- Integrates heritage skills training with the accelerated trade training program (Doc #157) — heritage skills sessions can be embedded within broader trade curricula (e.g., a blacksmithing module within the metalworking program)
Specific polytechnic-skill alignments:
| Polytechnic | Heritage skill focus | Rationale |
|---|---|---|
| Ara (Christchurch) | Blacksmithing, hand-tool metalwork | Strong engineering workshops; Canterbury heritage |
| NMIT (Nelson) | Timber boatbuilding | Existing boatbuilding community and maritime programs |
| Wintec (Hamilton) | Horse-drawn agriculture, coopering | Waikato agricultural heartland |
| Unitec (Auckland) | General heritage trades | Largest campus, largest population to draw from |
| SIT (Invercargill) | Stone masonry, rural heritage skills | Southland/Central Otago stone heritage |
| Tai Poutini (Greymouth) | Manual forestry, bush craft | West Coast forestry heritage |
| EIT (Napier) | Leather working, hand-tool woodwork | Hawke’s Bay farming and craft traditions |
| Otago Polytechnic (Dunedin) | Textile arts, hand-spinning | Southern textile heritage |
5.2 Marae
Marae are the natural institutional home for Māori heritage skills programs. They provide:
- A culturally appropriate setting for teaching and learning mātauranga Māori
- Existing community infrastructure (meeting house, kitchen, accommodation for students)
- Governance structures (marae committee, hapū/iwi authority) that can manage programs
- Connection to the land and resources relevant to the skills being taught (pa harakeke, rongoā plants, coastal access for waka programs)
Government role: Resource marae-based programs with materials, equipment, and funding — but do not manage them. The program is Māori-led. Government support means ensuring that practitioners who teach are compensated at rates comparable to polytechnic instructors, that materials are available, and that students can access the programs (transport, food, housing if needed).
5.3 Museums
NZ’s museum network holds physical collections, historical records, and institutional knowledge relevant to heritage skills:
- Te Papa Tongarewa (Museum of New Zealand): Māori material culture collections, historical technology collections, ethnographic documentation
- MOTAT (Museum of Transport and Technology, Auckland): Working heritage machinery, historical engineering equipment, volunteer community with hands-on skills
- Canterbury Museum / Otago Museum / Regional museums: Local heritage collections, often including tools and equipment from historical industries
- Toitū Otago Settlers Museum (Dunedin): Historical trades and industries of Otago
- New Zealand Maritime Museum (Auckland): Traditional boatbuilding, maritime heritage
Museums serve heritage skills preservation in three ways:
- Collections as teaching aids: Historical tools, equipment, and products can be used in teaching (with appropriate curation approval) or can be replicated as patterns for new production.
- Staff and volunteer knowledge: Museum staff and long-term volunteers often have significant knowledge about historical skills, having studied and sometimes practiced them.
- Documentation and archives: Museums hold photographs, plans, written descriptions, and oral history recordings of heritage skills that supplement living knowledge.
5.4 Community workshops and Men’s Sheds
NZ has approximately 100+ Men’s Sheds — community workshops where (predominantly) older men work on practical projects and share skills.34 These are distributed across the country and represent a significant concentration of heritage practical skills in an accessible, social setting. The Men’s Shed model:
- Provides existing workshop space (often well-equipped with hand and power tools)
- Connects older people with practical skills who enjoy teaching
- Offers a social framework that encourages participation (many elderly people will teach in a Men’s Shed who would not attend a formal polytechnic program)
- Can be rapidly expanded by providing additional tools and materials
Recommended approach: Fund and resource existing Men’s Sheds to expand their teaching role. Add formal structure (documented curricula, assessment where appropriate) while preserving the informal, social character that makes them effective. Use Men’s Sheds as satellite training sites for heritage skills that do not require heavy workshop infrastructure.
6. THE APPRENTICESHIP MODEL FOR HERITAGE SKILLS
6.1 Why formal apprenticeship matters here
Documentation captures information. Apprenticeship transmits capability. For the skills identified in Section 2, the goal is not to produce a library of heritage skills manuals (though that is valuable as a backup) — it is to produce a generation of young practitioners who can do the work. This means placing young people with heritage skills holders for extended periods of supervised, hands-on learning.
6.2 Structure
The heritage skills apprenticeship differs from the accelerated trade training program (Doc #157) in important ways:
| Feature | Accelerated trade training (Doc #157) | Heritage skills apprenticeship |
|---|---|---|
| Goal | Produce task-competent workers fast | Transmit deep craft knowledge |
| Duration | Weeks to months | 6 months to 3 years |
| Instructor | Professional trade instructor or multiplier-cohort graduate | Heritage practitioner (often elderly) |
| Training pace | Intensive, maximum throughput | Adapted to practitioner’s capacity — may be part-time |
| Class size | 4–8 trainees per instructor | 1–3 apprentices per practitioner |
| Assessment | Task competency demonstration | Gradual mastery assessed by practitioner |
Critical consideration: Heritage skills practitioners are often elderly and cannot sustain the pace of a full-time training program. A 78-year-old blacksmith may be able to teach for 3–4 hours per day, not 8. The apprenticeship structure must accommodate this — part-time teaching, rest days, flexibility for health issues. The practitioner’s comfort and willingness must take priority over program design, because without the practitioner there is no program.
6.3 Apprentice selection
For heritage skills apprenticeships, selection criteria differ from general trade training:
- Commitment: Heritage skills apprenticeship is not a 4-week course. Apprentices must be willing to invest months or years in learning a skill that may seem marginal now but becomes critical later.
- Aptitude for the specific skill: Not all practical aptitudes are the same. A good machinist is not necessarily a good blacksmith. Selection should involve a trial period where the apprentice works alongside the practitioner and both assess fit.
- Temperament: Working closely with an elderly practitioner, often in a one-on-one setting, requires patience, respect, and good interpersonal skills. Personality fit matters.
- Youth: Given the goal of transmitting knowledge across a generation gap, younger apprentices (18–35) are preferred — they have decades of productive use ahead.
- Geographic compatibility: Ideally, the apprentice lives near the practitioner. Relocating apprentices to distant practitioners is possible but adds cost and complexity.
6.4 Incentives and support for practitioners
Heritage skills holders must be motivated to participate. Most will not need financial incentives to share knowledge they care about — the opportunity to pass on their life’s work is often intrinsically motivating. But they do need practical support:
- Food security: Under rationing conditions (Doc #3), heritage skills practitioners should receive food allocations equivalent to workers in essential occupations. They are doing essential work.
- Transport: If the practitioner needs to travel to a training site, transport must be provided.
- Materials and tools: If the practitioner needs materials (steel for the forge, timber for the workshop, harakeke for the weaving), these must be supplied.
- Health care: Priority access to medical care for elderly practitioners, recognising that their continued participation depends on their health.
- Recognition: Formal acknowledgment of their contribution — not a certificate alone, but genuine public recognition that their knowledge is valued and their teaching matters. This requires minimal resources (public announcements, community events, government letters) and means a great deal to people who have often spent decades pursuing skills that the modern economy marginalized.
- Respect for pace and autonomy: The practitioner decides how and when they teach. They are the expert. Program administrators support them; they do not direct them.
6.5 Training scale-up targets for mātauranga Māori skills
The general apprenticeship model above applies to all heritage skills. For mātauranga Māori specifically, the following targets are coordinated through the Recovery Council (Section 4.6) and delivered through marae-based and wānanga-based programmes:
Year 1 targets:
| Domain | Trainees | Training duration | Training sites |
|---|---|---|---|
| Harakeke muka extraction | 200–500 | 2–4 weeks basic; 6–12 months for instructor level | 20–40 marae and community workshops |
| Rongoā identification and preparation | 50–100 | 3–6 months basic; 2–5 years for practitioner level | 10–20 marae with local medicinal plant access |
| Mahinga kai (harvest and preparation) | 100–300 | 1–4 weeks per food type | Regional marae and field sites |
| Traditional navigation | 10–30 | 6–12 months basic; years for full competence | Waka programmes, coastal marae |
| Kaitiakitanga resource management | 30–50 (regional managers) | 3–6 months workshop; ongoing mentorship | Wānanga and iwi environmental units |
Year 3 targets:
- 1,000–2,000 people with basic competency in at least one domain
- 100–200 people at instructor level (capable of teaching others — the cascade model from Section 7.3)
- 20–50 new rongoā practitioners with supervised clinical experience
- Harakeke processing integrated into industrial production (Doc #100)
- Kaitiakitanga frameworks operational in all regions with significant Māori land or resource holdings
These targets are estimates; actual numbers depend on practitioner availability and community capacity under recovery conditions.
7. THE DISTINCTION BETWEEN DOCUMENTATION AND LIVING PRACTICE
7.1 Why this distinction matters for policy
A government official, reviewing this document, might reasonably conclude that the priority is to produce comprehensive written and video documentation of every heritage skill — and then consider the job done. This would be a serious error.
Documentation is the backup plan. It preserves information against the worst case (all practitioners die before transmitting their knowledge). It is essential and should be pursued vigorously.
But documentation alone does not produce competent practitioners. A person who reads a blacksmithing manual and watches a video can attempt blacksmithing — and will produce poor results for a long time, making mistakes that a teacher would have corrected in minutes. They will waste material, damage tools, and potentially injure themselves in ways that supervised learning would prevent. They will develop bad habits that become harder to correct the longer they practice unsupervised. They may learn the procedures but miss the judgment that makes the procedures work.
The policy implication: Resources must flow to apprenticeship programs (Section 6), not only to documentation projects. Documentation is cheaper and easier to administer. Apprenticeship is messy, slow, depends on individual relationships, and is harder to report on. But apprenticeship produces blacksmiths. Documentation produces people who have read about blacksmithing.
7.2 Where documentation is primary
For some skills and some situations, documentation must serve as the primary transmission method because no practitioner is available:
- Skills where all NZ practitioners have died before apprenticeships could be established
- Skills held by very few practitioners who are geographically inaccessible to potential apprentices
- Skills where the practitioner is too frail to teach but can still be interviewed
- Supplementary skills (Tier 3 in Section 2) where the recovery value does not justify full apprenticeship programs but documentation preserves the option for later revival
In these cases, the best available documentation — ideally video with practitioner narration, supplemented by detailed written manuals — becomes the primary resource. People will have to learn from the documentation, and they will learn more slowly and less completely than they would from a teacher. But they will learn. Partial knowledge is better than no knowledge.
AI-assisted heritage skills access. The AI inference facility described in Doc #129, if operational, can substantially improve the usefulness of heritage skills documentation. The facility’s data archives can store and index video demonstrations, written manuals, and practitioner interviews across all heritage skill areas. When a community needs to learn a heritage technique — traditional flax processing, blacksmithing, pit saw operation, coopering — the AI system can identify and surface the most relevant video demonstrations and written guides from its archive, provide contextual guidance adapted to the specific situation (available materials, tools on hand, the learner’s existing skill level), and generate step-by-step instruction materials that bridge the gap between a general manual and a specific task. Community-level spoke devices (Doc #129) make this accessible at the point of need — a farming community attempting horse-drawn ploughing for the first time can access guidance at the paddock, not at a distant library. This does not solve the fundamental problem of embodied knowledge — the AI system cannot teach a blacksmith to read heat colour or a spinner to control tension. But for the procedural components of heritage skills, and particularly for the early stages of self-teaching where learners make the most avoidable mistakes, AI-mediated access to documented practitioner knowledge is a meaningful supplement. It also helps identify which heritage skills have been documented and where gaps remain, supporting the ongoing documentation effort.
7.3 The cascade model for heritage skills
The accelerated trade training document (Doc #157) describes a cascade or multiplier model where first-cohort graduates become trainers for the second cohort. The same model applies to heritage skills, but with a longer timeline and more emphasis on quality:
Year 1: Elderly practitioner teaches 1–3 apprentices intensively (alongside documentation recording).
Year 2–3: Apprentices reach working competence. They are not masters — that takes a decade — but they can produce useful work and, crucially, they can teach the basics to new learners. The original practitioner continues to supervise and correct, passing on deeper knowledge.
Year 3–5: First-generation apprentices are teaching their own apprentices. The original practitioner serves as a consultant and quality reference — even if they can no longer work at the forge or the lathe, they can watch, advise, and correct.
Year 5+: If the original practitioner is no longer available, the first-generation apprentices carry the knowledge forward. The chain is not as strong as an unbroken lineage of master craftspeople, but it preserves the essential knowledge.
The urgency derives from this cascade timeline: If year 1 is delayed by 3 years, and the practitioner dies in year 2, the entire cascade collapses. The window is not theoretical — it is defined by the lifespan of specific, identifiable people.
8. DEPENDENCY CHAINS
8.1 What this document depends on
| Dependency | Source | Criticality |
|---|---|---|
| Skills census to identify practitioners | Doc #8, #158 | High — but begin identification through other channels immediately |
| Functioning video recording equipment | Existing electronic stocks | High for documentation phase — degrades over time |
| Printing capability for manuals | Doc #29, #30 | Medium — needed for print distribution but not for apprenticeship |
| Workshop space at polytechnics | Doc #157 (trade training infrastructure) | Medium — heritage training can also occur in practitioners’ own workshops |
| Materials for training (steel, timber, fiber, leather) | Doc #1, #7 (consumable management) | Medium — heritage skills often use scrap and locally sourced materials |
| Government coordination | Doc #157, #144 (emergency powers) | Medium — program can begin through community networks without formal government direction |
| Food and housing for practitioners and apprentices | Doc #3 (rationing) | High — people must be fed |
8.2 What depends on this document
| Dependent capability | Document | Dependency type |
|---|---|---|
| Blacksmithing workforce | Doc #92 | Trained blacksmiths come partly through heritage skills preservation |
| Timber boatbuilding | Doc #138, #141 | Experienced timber builders are the binding constraint |
| Harakeke fiber processing | Doc #100 | Knowledge holders are the starting point for all fiber production |
| Horse-drawn agriculture | Doc #74 (pastoral farming) | If tractors fail, horse skills are essential |
| Hand-spinning and weaving workforce | Doc #36 (wool textiles) | Heritage spinners and weavers train the next generation |
| Traditional navigation | Doc #139 (celestial navigation) | Polynesian wayfinding knowledge supplements Western methods |
| Rongoā Māori integration into health system | Doc #24 (NZ flora reference) | Practitioner knowledge enables practical use of plant references |
| Machine shop hand skills | Doc #91 (machine shop operations) | Hand scraping, fitting, and layout are heritage skills within machining |
| HF radio knowledge | Doc #128 (HF radio network) | Older operators hold valve-equipment and CW (Morse code) knowledge |
| Wire rope splicing | Doc #52 | Splicing is a manual skill best taught person-to-person |
9. CRITICAL UNCERTAINTIES
| Uncertainty | Impact if wrong | Resolution method |
|---|---|---|
| Number of heritage skills holders in NZ | If fewer than estimated, the preservation window is shorter and urgency is higher | Skills census (Doc #8) and community-based identification |
| Willingness of practitioners to participate | If low, program scope shrinks | Outreach through trusted community channels; respect autonomy; provide practical support |
| Willingness of Māori communities to share knowledge within program framework | Without Māori participation, the highest-value traditional skills are not preserved | Genuine partnership approach; Māori governance of Māori knowledge programs |
| Physical capacity of elderly practitioners to teach | If practitioners are frailer than assumed, teaching hours are fewer | Adapt program pace; prioritise video documentation for most vulnerable |
| Quality of knowledge transfer through documentation vs. apprenticeship | If documentation is less effective than assumed, late-documented skills may not be transmissible | Prioritise apprenticeship over documentation wherever possible |
| Apprentice completion and retention rates | If apprentices drop out at high rates, the cascade model weakens | Select for commitment; provide meaningful support and recognition |
| Durability of video recording equipment and storage | If equipment fails faster than estimated, documentation window closes sooner | Begin immediately; backup to multiple media; transcribe to print |
| Recovery value of specific heritage skills | Some skills may prove less useful than estimated (e.g., if tractors remain operational, horse-drawn agriculture is less critical) | Accept uncertainty; preserve broadly because the cost of documentation is low relative to the cost of losing knowledge permanently |

FOOTNOTES
The estimate of 200–800 person-hours per year saved by a competent blacksmith is derived as follows: a farming community of 50–200 people performing manual tasks with improvised or worn tools may lose 4–8 hours per week per skilled worker versus tasks completed with purpose-made implements (plough shares, hoes, axes, harness hardware). At 50 workers and 4 hours/week waste: 200 × 52 = 10,400 person-hours/year. At 200 workers and 8 hours: 200 × 8 × 52 = 83,200 hours — but most of those tasks cannot be deferred indefinitely, so the more conservative figure of 200–800 hours reflects the plausible range for implement maintenance and repair savings (new versus missing or broken hardware) rather than total productive loss. This estimate requires verification from agricultural historians or heritage farmers. No published NZ-specific figure is available to the author.↩︎
Draft horse versus hand labour comparison: Historical NZ and Australian pastoral records suggest a team of two Clydesdale horses with an experienced driver could plough 0.4–0.8 hectares per day on NZ loam-class soils with a single-furrow plough. Hand cultivation (spade or fork) of the same area would require approximately 8–20 person-days per hectare depending on soil type and cultivation depth. The 4–12 hand-labourer equivalence stated in the body is derived from this ratio across typical harrowing, ploughing, and cartage tasks combined. See: McLauchlan, G., “The Story of New Zealand,” Whitcoulls, 1984 (contextual); and Steele, H.T., “Farming in Early New Zealand,” Dunmore Press, 1975. These figures require verification from equine historians or draft horse societies. NZ Clydesdale Horse Society: https://www.clydesdalehorsenewzealand.co.nz/↩︎
The concept of tacit or embodied knowledge is well-established in philosophy of knowledge and craft theory. See: Polanyi, M., “The Tacit Dimension,” Doubleday, 1966 — the foundational text arguing that “we can know more than we can tell.” Applied to craft skills: Sennett, R., “The Craftsman,” Yale University Press, 2008. The application to recovery scenarios is that skills with high tacit-knowledge content are the most vulnerable to permanent loss because they resist documentation.↩︎
The limits of documentation as a substitute for apprenticeship are well-documented in the craft education literature. See: Dormer, P. (ed.), “The Culture of Craft,” Manchester University Press, 1997. Also: Crawford, M.B., “Shop Class as Soulcraft,” Penguin, 2009. The general finding is that documentation can convey procedure but not judgment, and that the gap between documented procedure and competent practice ranges from small (for well-defined, repeatable processes) to very large (for skills requiring continuous adaptation to variable materials and conditions).↩︎
Stats NZ, population estimates by age. https://www.stats.govt.nz/ — NZ’s population aged 65+ has been approximately 850,000–900,000 in recent years and growing as the population ages. The subset with heritage skills relevant to this document is not separately tracked in any data source known to the author.↩︎
Stats NZ, period life tables. https://www.stats.govt.nz/ — Life expectancy at age 80 for NZ men is approximately 8–9 years; for NZ women, approximately 10–11 years (varies by the specific period table used). These are pre-event figures; life expectancy under recovery conditions (reduced healthcare access, increased physical demands, psychological stress, possible nutritional decline) may be lower, particularly for elderly people with chronic conditions dependent on imported medications (Doc #20).↩︎
Ministry of Health, “Health and Independence Report” and related publications. https://www.health.govt.nz/ — Māori life expectancy at birth remains approximately 4–7 years lower than non-Māori, depending on the measure used and the year of estimate. The gap has narrowed over recent decades but remains significant. This is relevant to heritage skills preservation because it means the window for capturing knowledge from Māori elders is narrower than from non-Māori elders of the same age.↩︎
NZ age-specific mortality rates: Stats NZ, “New Zealand Period Life Tables,” https://www.stats.govt.nz/ — Age-specific mortality rates for NZ (pre-event, 2020–2022 period life table): aged 70–74, approximately 1.5–2.5% per year for men, 1.0–1.7% for women; aged 75–79, approximately 2.5–4.0% for men, 1.8–2.8% for women; aged 80–84, approximately 5–8% for men, 3.5–5.5% for women; aged 85+, approximately 10–18% for men, 8–14% for women. The body text uses “2–4% for aged 70–79” and “8–15% for aged 80+” as rounded illustrative ranges — these are broadly consistent with the published data, slightly conservative for the 70–74 age band and slightly generous for the 80–84 band. Under recovery conditions, mortality rates may increase for elderly people with chronic conditions dependent on imported medications.↩︎
Blacksmithing as a recovery skill: See Doc #92 for full treatment. The historical role of the blacksmith in pre-industrial communities — as the maker and repairer of metal tools, hardware, agricultural implements, and household items — resumes under conditions where mass-manufactured alternatives are unavailable. NZ’s recovery manufacturing strategy (Doc #92–118) includes both machine shop production (precise, equipment-dependent) and blacksmithing (adaptable, lower-precision, less equipment-dependent).↩︎
Artist Blacksmith Association of New Zealand (ABANZ). https://www.abanz.co.nz/ — ABANZ membership provides a partial listing of NZ blacksmiths but does not represent all practitioners (hobbyists, rural farmers with forge skills, and unaffiliated smiths are not captured). The estimate of 50–100 regularly practising blacksmiths is from Doc #92, footnote 27, and is acknowledged as rough.↩︎
NZ anvil stock: The estimate of 500–2,000 anvils nationwide is a rough inference based on the number of active and former blacksmiths, rural farriers, and heritage tool collections in NZ. No inventory of NZ anvils exists. For context: NZ had approximately 5,000–8,000 working farms before mechanisation (pre-1950s), many of which had forges; the survival fraction of those anvils is unknown but likely low. The Federated Farmers heritage group, ABANZ, and museum collections are the most likely repositories of data. Anvil manufacture from cast iron is possible but requires a large pattern (cast iron is brittle and unsuitable for an anvil face); a true wrought-iron or steel anvil requires substantial steel forging or machining capability — effectively a Doc #91/92 level project requiring several tonnes of high-carbon steel.↩︎
NZ timber boatbuilding: The NZ boatbuilding industry has substantially transitioned from timber to composite (fiberglass) and aluminium construction since the 1970s. A small number of builders continue timber construction, concentrated around the traditional boatbuilding centres of Nelson, Auckland (Devonport, Westhaven), and Bay of Islands. The Traditional Boat Building School (based in Auckland, operated by the NZ Maritime Museum) teaches timber boatbuilding skills but at small scale. See also Doc #138 (Sailing Vessel Design), Doc #141 (Boatbuilding Techniques).↩︎
Timber seasoning for boatbuilding: Green timber cannot be used for planked boat construction — it will shrink, split, and open seams as it dries. Proper seasoning (air-drying under cover) requires approximately 1 year per 25mm of thickness for most species. Boat planking is typically 25–38mm thick (1–1.5 years minimum drying), with frames and keels being thicker (50–75mm, requiring 2–3 years). Kiln-drying can accelerate this to weeks but requires substantial heat input and risks case-hardening in dense timbers. NZ species: kauri (Agathis australis), now largely protected and not available for new felling; acceptable alternatives include puriri (Vitex lucens), pohutukawa (Metrosideros excelsa), totara (Podocarpus totara) for frames, and Douglas fir from plantation forestry for planking. See: Chapelle, H.I., “Boatbuilding,” Norton, 1941; and Steward, J.R., “Clinker Plywood Boatbuilding Manual,” Tiller Publishing, 2000.↩︎
Waka building: Traditional Māori canoe construction uses techniques distinct from European boatbuilding — notably the use of a single large log (totara or other suitable timber) for the hull (waka tīwai and waka taua) or multiple shaped timbers lashed and sealed (waka hourua). The revival of waka hourua building in NZ since the 1980s, led by navigators and builders including the late Tā Hekenukumai Puhipi Busby (d. 2019), produced functional ocean-going vessels and trained a small number of younger practitioners. See: Irwin, G., “The Prehistoric Exploration and Colonisation of the Pacific,” Cambridge University Press, 1992.↩︎
The number of expert waka builders in NZ is very small and not formally tracked. Tā Hekenukumaingaiwi Puhipi Busby (Sir Hector Busby, 1 August 1932 – 11 May 2019), who was central to the NZ waka hourua revival, was knighted in the 2018 Queen’s Birthday Honours for his contributions to Māori. See: Te Papa Blog, “Remembering Tā Hekenukumaingaiwi Puhipi Busby,” May 2019. https://blog.tepapa.govt.nz/2019/05/15/remembering-ta-hek... — A small number of builders who trained with or alongside Busby hold knowledge that has been partially transmitted to younger practitioners through programs such as Te Toki Voyaging Trust. The knowledge base remains narrow. Figures on the number of trained builders should be verified through direct engagement with waka organisations.↩︎
NZ horse population: Stats NZ and equine industry estimates suggest NZ has approximately 70,000–80,000 horses. The vast majority are sport and recreational horses. Draft breeds (Clydesdales, Percherons, Shires) are a small minority — perhaps 2,000–5,000 nationally. The Clydesdale Horse Society of NZ and the Percheron Horse Association of NZ maintain breed registries. Converting recreational horses to draft work is possible for some animals but the skills for working with draft horses (harnessing, driving, implement use) are a separate skillset from recreational riding.↩︎
Rongoā Māori: Riley, M., “Māori Healing and Herbal,” Viking Sevenseas, 1994. Also: Brooker, S.G., Cambie, R.C., and Cooper, R.C., “New Zealand Medicinal Plants,” Heinemann, 1981. Many rongoā preparations contain pharmacologically active compounds (e.g., kawakawa contains myristicin with anti-inflammatory properties; koromiko has documented antibacterial activity). Standardised dosing, quality control, and contraindication awareness are less developed than in modern pharmacology. Rongoā complements modern medicine where available; it does not substitute for it in acute or critical care.↩︎
Hand-tool woodworking: The revival of hand-tool woodworking as a practice (distinct from its role as a hobby) is relevant to recovery because electric power tool consumables — sandpaper, router bits, saw blades, batteries for cordless tools — are imported consumables with finite stocks. Hand tools (planes, chisels, handsaws, draw knives) can be resharpened indefinitely and repaired locally. The skills for effective hand-tool use, particularly hand planing and saw sharpening, are substantially different from power-tool woodworking and require dedicated training. See: Schwarz, C., “The Anarchist’s Tool Chest,” Lost Art Press, 2011 — a practical treatise on hand-tool woodworking.↩︎
NZ wool production: Beef + Lamb New Zealand Economic Service. https://beeflambnz.com/ — NZ produces approximately 120,000–140,000 tonnes of wool per year. Under nuclear winter conditions, wool production will decline with livestock carrying capacity, but NZ will still produce far more wool than its population can consume if it has the processing capability to convert raw fleece to finished textiles. See Doc #36.↩︎
NZ Spinning, Weaving and Woolcrafts Society. https://www.creativefibres.org.nz/ — The society has branches throughout NZ and holds annual exhibitions, workshops, and conferences. Membership numbers fluctuate but are estimated in the low thousands. The proportion who can hand-spin at production rates (i.e., producing yarn in useful quantities rather than as a leisure activity) is a subset. Expert production spinners — those who can produce consistent, strong yarn for weaving — are a smaller subset still, and disproportionately elderly.↩︎
Te Rōpū Raranga Whatu o Aotearoa (National Māori Weavers Collective): Established 1983 to support Māori weaving nationally. See Doc #104, footnote 30, for detail. The number of expert kairaranga is not formally tracked. The estimate of “a few hundred” expert practitioners is based on community knowledge and the scale of annual weaving hui attendance.↩︎
Leather tanning and saddlery in NZ: NZ’s tanning industry processes hides industrially (chrome tanning) for export and domestic use. Small-scale and vegetable tanning — the methods relevant to recovery-era production without imported chromium salts — are practised by very few people. Saddlery (making saddles, harness, and leather goods by hand) is a small trade serving the equestrian market. See Doc #101.↩︎
Vegetable tanning performance gap: Chrome-tanned leather (the current NZ commercial standard) uses chromium(III) sulfate salts in a 1–2 day process to produce soft, supple, heat-stable leather uniform in properties. Vegetable-tanned leather (using tannins from bark — black wattle Acacia mearnsii is the most available NZ source of commercial-grade tannin; radiata pine bark contains some tannin but at lower concentrations) requires 4–12 weeks immersion in progressively stronger tannin solutions and produces stiffer, more water-absorbent leather that darkens and hardens when wet. Vegetable leather is entirely adequate for harness, belts, book bindings, and heavy footwear; it is inferior for fine shoe uppers, garments, and applications requiring flexibility when wet. Black wattle (an introduced species present throughout NZ, particularly in Northland, Bay of Plenty, and Canterbury) has bark tannin content of 20–40% — adequate for vegetable tanning. See: McLaughlin, G.W. and Theis, E.R., “The Chemistry of Leather Manufacture,” Reinhold, 1945; and NZ Forest Research Institute references on tanbark species.↩︎
Stone masonry in NZ: NZ has diverse building stone — Oamaru limestone, Central Otago schist, Coromandel granite, Kaikōura limestone, various basalts and volcanic stone. Historical stone buildings in NZ (particularly in Canterbury, Otago, and Wairarapa) demonstrate that the stone is suitable for construction. The craft of working it — cutting, dressing, laying — is nearly lost in NZ. Heritage NZ Pouhere Taonga maintains some institutional knowledge through its conservation work on heritage stone buildings. See also: Salmond, J., “Old New Zealand Houses 1800–1940,” Reed, 1986.↩︎
NZ stone masonry practitioners: No formal census of NZ stone masons with traditional (pre-machine) skills exists. Heritage NZ Pouhere Taonga maintains contractor lists for conservation work on scheduled historic buildings, which includes stone masonry, but most such work is done by general heritage contractors rather than traditional stone masons. Dry stone walling skills in Central Otago and Canterbury (where extensive pastoral-era stone walls survive from the 1860s–1900s) are largely extinct among working practitioners. The Dry Stone Walling Association of Great Britain has a small affiliated following in NZ; contact through Heritage NZ may identify current practitioners. The estimate of 20–50 in the body is an upper bound and should be treated as unverified until the skills census (Doc #8) establishes the actual figure.↩︎
Coopering: The craft of making wooden barrels and casks is globally endangered. In NZ, a very small number of coopers are associated with the wine and whisky industries. The skill is relevant to recovery because wooden vessels are containers that can be made entirely from local materials (NZ oak and other suitable timbers) for liquids and bulk goods. Standard reference: Kilby, K., “The Cooper and His Trade,” Linden Publishing, 1971.↩︎
Coopering as an endangered skill: The craft of traditional coopering has declined globally since the 1950s with the introduction of stainless steel, aluminium, and plastic containers. The spirit and wine industries maintain demand for oak barrels (for flavour development) and sustain a small number of cooperages globally, but the knowledge base is highly concentrated. In NZ, cooperages serving the wine industry are located primarily in Marlborough (near Blenheim) and Hawke’s Bay. The NZ whisky industry (operating at small scale from Distillery Willowbank heritage in Dunedin and newer craft distillers) also generates some demand. No comprehensive census of NZ coopering practitioners exists; the figure of 5–15 is an informed estimate based on industry contacts and should be verified through the NZ wine industry body New Zealand Winegrowers: https://www.nzwine.com/↩︎
NZ pottery and ceramics: NZ has a notable studio pottery tradition but very few production potters working at the scale relevant to recovery (making large numbers of functional vessels — storage jars, water containers, drainage pipe, bricks). NZ clays are generally suitable for pottery and brick-making. The Temuka pottery (South Canterbury) operated from the 1870s to the 1990s, producing functional ceramics from local clay, demonstrating that production-scale ceramics from NZ materials is feasible. Some NZ potters (particularly those trained in the Japanese functional pottery tradition, which has NZ adherents) produce functional ware that is directly relevant.↩︎
Men’s Sheds NZ: The Men’s Shed movement, originating in Australia, has approximately 100+ active sheds in NZ as of recent years. See: https://menzshed.org.nz/ — Each shed typically has a workshop with basic to intermediate hand and power tools and a membership of 10–50+ predominantly older men. The sheds serve a social function (addressing social isolation among retired men) as well as a practical function (producing items for the community, maintaining skills). Under recovery conditions, their practical function becomes primary.↩︎
Historical extractive approaches to Māori knowledge: The Crown’s relationship with mātauranga Māori has included periods of active suppression (the Tohunga Suppression Act 1907, which prohibited Māori healers from practising) and periods of academic extraction (documenting Māori knowledge in European frameworks without community control). The Tohunga Suppression Act was not repealed until 1962. See: Durie, M. (1998), “Te Mana, Te Kāwanatanga: The Politics of Māori Self-Determination,” Oxford University Press; Waitangi Tribunal (2011), “Ko Aotearoa Tēnei” (Wai 262), Chapter 2.↩︎
Māori resistance to extractive knowledge programmes is well-documented. See: Smith, L.T. (1999), “Decolonizing Methodologies: Research and Indigenous Peoples,” Zed Books — the foundational text on indigenous research methodology, written by a NZ Māori scholar. The consistent finding is that indigenous communities participate more willingly, share more deeply, and produce better outcomes when they have governance over research processes.↩︎
Waitangi Tribunal (2011), “Ko Aotearoa Tēnei: A Report into Claims Concerning New Zealand Law and Policy Affecting Māori Culture and Identity” (Wai 262). The report establishes that Māori have a legitimate interest in controlling how their traditional knowledge is recorded, stored, and disseminated. See footnote 22 for the full citation and URL.↩︎
Māori intellectual property and indigenous knowledge rights: The Wai 262 (Ko Aotearoa Tēnei) report from the Waitangi Tribunal (2011) addresses Māori rights over traditional knowledge, including cultural practices, taonga species, and mātauranga Māori. The report establishes that Māori have a legitimate interest in controlling how their traditional knowledge is recorded, stored, and disseminated. Any heritage skills program involving mātauranga Māori must be consistent with these principles. See: Waitangi Tribunal, “Ko Aotearoa Tēnei: A Report into Claims Concerning New Zealand Law and Policy Affecting Māori Culture and Identity,” 2011. https://waitangitribunal.govt.nz/↩︎
