EXECUTIVE SUMMARY

Doc #36 (Clothing and Footwear) establishes that NZ’s existing clothing stocks cover approximately 2–4 years under managed conditions, with work clothing, children’s sizes, socks, and underwear depleting first. After that window closes, every outdoor worker clearing land for emergency cropping (Doc #76), every child growing through three sizes in two years, every forestry crew member (Doc #76), and every construction worker (Doc #97, Doc #164) depends on domestically manufactured textiles. This document addresses the manufacturing capability that must exist before stocks run out.

The lead time is the critical issue. Building spinning frames takes months of machine shop time. Training weavers takes 3–6 months. Constructing power looms is a multi-year project. If NZ waits until wardrobes are empty to begin building textile infrastructure, there will be a gap of years between need and production. Work that begins in Year 1 determines whether NZ has adequate clothing by Year 5.

New Zealand has the raw materials for a domestic textile industry — wool in extraordinary quantity, harakeke fiber, possum fur, leather from millions of hides — but almost no manufacturing infrastructure to convert those materials into finished textiles and garments. The country’s last significant garment factories closed decades ago.1 NZ’s wool scouring and processing industry has contracted to a handful of operations. There are no domestic spinning mills, no power looms, no industrial knitting factories, and no commercial tanning operations at meaningful scale.

This document addresses the manufacturing gap: the equipment, facilities, skills, and staged development pathway needed to build a textile industry from NZ’s existing raw material base. It is a companion to Doc #36 (which covers the broader clothing and footwear situation including existing stocks, raw materials, and repair) and Doc #100 (which covers harakeke fiber processing). Where those documents describe what NZ has and what it needs, this document describes how to build the machines and train the people to get from raw fiber to finished textile products at scale.

The core problem is not invention — every technology needed is well-understood, most of it dating to the 18th or 19th century. The problem is capacity. NZ has perhaps a few thousand craft spinners, a few hundred hand weavers, and a scattering of knitting machines in private homes. Clothing 5.2 million people requires output several orders of magnitude beyond current artisan production. Closing that gap requires building industrial textile machinery in NZ machine shops, training thousands of new textile workers, and establishing processing facilities from scouring through to garment finishing — all while those same machine shops and workers are needed for dozens of other recovery priorities.

The timeline is not desperate. Existing clothing stocks cover the first 2–4 years (Doc #36, Section 1.4). But the lead time for equipment fabrication, training, and production scale-up means that work must begin in Year 1 to avoid a clothing gap in Years 4–7. The dependency chain is long but entirely domestic: wool from NZ sheep, steel from NZ Steel Glenbrook (Doc #89) for machinery, electricity from NZ’s renewable grid, skills from NZ’s existing craft communities and heritage practitioners. No imported materials are required at any stage of the core production chain.

What NZ cannot make: Elastic, zippers at scale, synthetic fabrics (polyester, nylon, acrylic), cotton textiles, and rubber-soled footwear. These depend on materials NZ does not have and cannot produce. Garment design must adapt to use buttons, ties, drawstrings, and wool or harakeke alternatives. This is a permanent constraint unless trade provides access to these materials.

Contents

Phase 1 (Months 0–12): Preparation — no manufacturing needed yet

  1. Include textile manufacturing assets in the national asset census (Doc #8). Specifically: all industrial sewing machines, knitting machines (domestic and industrial), spinning wheels, spinning frames, looms (hand and power), carding machines, scouring equipment, tanning vats, and associated tooling. Also: stocks of sewing notions (thread, needles, zippers, elastic, buttons) in retail and wholesale channels.2
  2. Identify skilled practitioners through the skills census: spinners, weavers, knitters, dyers, tailors, seamstresses, cobblers, tanners, pattern-makers. Register these people — they become the training cadre.
  3. Engage the Weavers, Spinners and Woolcrafts NZ national body and local guilds, and the National Maori Weavers Collective (Te Ropu Raranga Whatu o Aotearoa). These organisations hold the knowledge and become partners in scaled-up production.3
  4. Secure Ashford Handicrafts Ltd (Ashburton) as a critical national asset.4 This factory produces spinning wheels, looms, and textile equipment. Under recovery conditions, it should shift to producing equipment for the national textile program. Assess its capacity, workforce, raw material needs, and potential for expanded production.
  5. Secure existing wool processing chain. Ensure wool scouring plants remain operational. All wool that would normally be exported stays in NZ.
  6. Do not spend political capital on textile manufacturing in Phase 1. The government has more urgent priorities. These preparatory actions integrate into the asset census and skills census that are already happening for other reasons.

Phase 2 (Years 1–3): Build capability

  1. Launch spinning and weaving training programs using guild members and heritage practitioners as instructors. Target: 5,000–10,000 new hand-spinners and 1,000–2,000 new hand-weavers trained within two years.
  2. Commission Ashford Handicrafts and NZ machine shops (Doc #91) to build textile equipment. Priority order: (a) carding machines, (b) multi-spindle spinning frames, (c) floor looms, (d) knitting machine components. Target: 50–100 carding machines, 20–50 spinning frames, and 200–500 new looms fabricated by end of Year 3.
  3. Establish 10–20 regional textile processing centres, each with scouring, carding, spinning, and weaving/knitting capability. Located near wool supply (sheep farming regions) and population centres.
  4. Organise community knitting production for the highest-priority items: socks, underwear, hats, gloves, children’s clothing. Deploy identified domestic knitting machines to production centres or skilled operators.
  5. Begin tanning operations using vegetable tanning with NZ bark sources (wattle, manuka, tanekaha). Target: 2–3 pilot tanneries operational by end of Year 2 (Doc #36, Section 7.2).
  6. Begin producing NZ-made sewing thread from wool and muka (harakeke fiber). Commercial polyester thread stocks will deplete; domestic thread production is needed before that happens.
  7. Establish button production from bone, horn, shell (paua, mussel), and wood. Bone is abundant from meatworks. This is low-technology manufacturing suitable for community-level production.

Phase 3 (Years 3–7): Scale to meaningful output

  1. Commission power looms built in NZ machine shops. These are the single most important piece of textile manufacturing equipment for volume production. Target: first power looms operational by Year 4–5.
  2. Scale yarn production through multi-spindle spinning frames. Target: domestic yarn output sufficient for national clothing needs by Year 7.
  3. Scale footwear production. Regional cobbling workshops producing new boots and shoes from NZ-tanned leather. Target: 50,000+ pairs per year by Year 5.
  4. Develop fulled wool fabric production (broadcloth, melton) for outerwear — wind-resistant, water-resistant, durable.
  5. Develop oilskin production for waterproof garments using woven fabric treated with linseed oil or tallow wax.

Phase 4 (Years 7–15): Industrial textile capability

  1. Industrial knitting machines built in NZ or acquired through trade. High-volume sock and underwear production.
  2. Multiple wool mills operating power looms producing fabric at industrial scale.
  3. Full tanning industry for footwear, belts, bags, protective clothing.
  4. Explore trade-sourced materials: rubber for soles (from tropical regions), cotton (if obtainable), elastic (if synthetic production develops elsewhere).

ECONOMIC JUSTIFICATION

Cost of the textile manufacturing program

The manufacturing program competes for the same scarce resources — machine shop time, skilled labour, steel, engineering attention — that are needed for dozens of other recovery priorities (Doc #91, Doc #97, Doc #164, Doc #135). The economic case must demonstrate that textile manufacturing is worth the investment.

Direct costs (estimated person-years):

Component Person-years (Years 1–3) Person-years (Years 3–7)
Equipment fabrication (machine shop time) 30–60 50–100
Training program (instructors and coordination) 20–40 10–20
Trainee labour (productive after initial training) 100–300 500–2,000
Facility construction (scouring plants, processing centres) 20–40 30–60
Tannery establishment and operation 10–20 20–50
Total ~180–460 ~610–2,230

The trainee labour line is large but misleading as a pure cost — trainees are producing clothing while training, so much of this labour is productive output, not overhead.

Comparison: what happens without a textile program

Without domestic manufacturing, NZ draws down existing clothing stocks (Doc #36, Section 1.4): adequate for Years 0–3, thinning in Years 3–7, severe shortages by Years 7–15. Under nuclear winter conditions, inadequate clothing causes hypothermia, reduced work capacity, and preventable death among outdoor workers, the elderly, and children. People will improvise — but hand methods alone require approximately 200,000 full-time textile workers to clothe NZ (Doc #36, Section 4.4), compared to 10,000–50,000 with modest mechanisation. The manufacturing program pays for itself many times over in freed labour.

Breakeven

The equipment fabrication investment (30–60 person-years in Years 1–3) begins returning value as soon as the first machines are operational. A single multi-spindle spinning frame operated by one person produces as much yarn as 10–50 hand-spinners.5 Over a 10-year operational life, one spinning frame (requiring perhaps 0.5 person-years of machine shop time to build) saves 100–500 person-years of hand-spinning labour. The return on investment is extremely high.

Power looms show similar economics: one power loom operated by one person produces as much fabric as 10–50 hand weavers.6 The machine shop investment to build a power loom is perhaps 1–2 person-years; the labour saved over a decade is 100–500 person-years.

A labour-type distinction matters here: the 100–500 person-years of hand-spinning labour that each machine saves would come from the general population — people who are available and otherwise underemployed — while the 0.5–2 person-years of machine shop time required to build the equipment draws from a scarce specialist pool with competing demands across dozens of recovery programmes. The return on investment is still extremely high, but the real cost of the machine shop time is greater than the raw person-year figure suggests.

Assessment: Textile equipment fabrication is among the highest-return uses of machine shop time in the entire recovery program. The case for prioritising it is strong.

1. THE MANUFACTURING GAP

1.1 What NZ had

NZ once had a significant textile manufacturing industry. From the 1870s through the mid-20th century, wool mills operated in Dunedin (Mosgiel Woollens, est. 1871), Kaiapoi, Timaru, Milton, Wanganui, Onehunga, and other centres.7 These mills employed thousands of workers and operated spinning frames, power looms, finishing equipment, and dyeing facilities — precisely the equipment NZ needs to rebuild. Surviving equipment from these historical mills, if any remains in museums or storage, would be valuable as reference or for refurbishment.

1.2 What NZ has now

The industry contracted steadily from the 1960s onward due to trade liberalisation and cheap imports from Asia. By the 2020s:8

  • No operating wool mills producing fabric at industrial scale for the domestic market.
  • A few small-scale processors producing high-end yarn for the craft and export market.
  • Wool scouring plants (Cavalier, NZ Wool Services International) — these remain and are critical to retain.
  • Ashford Handicrafts Ltd (Ashburton) — manufactures spinning wheels, looms, and textile accessories for the international craft market. This is arguably NZ’s single most important textile manufacturing asset under recovery conditions.9
  • A handful of small garment makers producing premium NZ-made clothing, primarily wool knitwear and outdoor clothing (e.g., Untouched World, Swanndri).
  • No industrial knitting factories, no power loom operations, no commercial spinning mills.

1.3 The gap in numbers

Capability Current NZ capacity Required for self-sufficiency Gap factor
Wool scouring 100,000+ tonnes/year (existing plants) 30,000–60,000 tonnes/year Adequate — existing capacity exceeds recovery-era need
Carding Small-scale only (craft operations) 30,000–60,000 tonnes/year throughput ~100–1,000x
Spinning (industrial) Effectively zero 20,000–40,000 tonnes yarn/year Near-total gap
Weaving (industrial) Effectively zero Millions of metres of fabric/year Near-total gap
Knitting (industrial) Effectively zero (some domestic machines) Millions of garments/year Near-total gap
Garment sewing (industrial) Small-scale only Millions of garments/year ~100x
Tanning Very small-scale Millions of hides/year ~100x

Wool scouring is the one step where existing industrial capacity meets or exceeds recovery-era demand. Every other step in the manufacturing chain must be built from near-zero.

2. THE EQUIPMENT: WHAT NZ NEEDS TO BUILD

2.1 Carding machines

Function: Open, clean, and align wool fibers into a continuous web or roving (sliver) ready for spinning.

Design: A drum carder consists of a large cylinder (the main drum or swift, typically 300–600 mm diameter) covered in card clothing (wire-toothed fabric) and one or more smaller feed rollers (lickers-in), also covered in card clothing. Fiber is fed onto the licker-in, transferred to the swift, and removed as a continuous web. Industrial carders add additional rollers (workers and strippers) to improve fiber opening and alignment.10

NZ fabrication requirements:

  • Steel rollers and shafts — lathe work (Doc #91)
  • Card clothing — fine bent wire mounted in a backing fabric or rubber sheet. This is the most specialised component. The full dependency chain: NZ Steel Glenbrook (Doc #89) produces steel rod → wire drawing through progressively smaller dies (Doc #105) reduces rod to fine gauge (approximately 0.3–1.0 mm diameter) → individual wires are cut, bent to a hooked profile on a forming jig, and mounted by hand into a rubber or leather backing. The wire drawing step requires hardened steel dies and drawing lubricant; this is within NZ’s fabrication range but requires dedicated tooling development early in Phase 2. Without functional card clothing, carding machines cannot process fiber regardless of the quality of the drum and roller fabrication.
  • Frame — steel or timber
  • Bearings — from existing stocks or machined (Doc #96)
  • Electric motor drive — sourced from existing industrial motors (secured through asset census) or wound from NZ-drawn copper wire (Doc #91) onto machined steel cores. Functional under baseline grid assumptions.

Complexity assessment: Moderate. A functional carding machine can be built in a well-equipped machine shop in 2–4 weeks. The card clothing is the hardest component. Historical NZ mills imported card clothing, but the wire itself is within NZ Steel’s product range, and mounting it is a manual process.11

Throughput: A single industrial carding machine processes 50–200 kg of fiber per hour depending on size and design.12 Ten machines could process 100–400 tonnes per month — adequate for a significant fraction of national demand.

2.2 Spinning frames

Function: Draw out carded roving and twist it into yarn.

Design: A spinning frame holds multiple spindles (historically 20–200+ per frame) operating simultaneously. Each spindle draws fiber from a roving bobbin, twists it by rotation, and winds the finished yarn onto a bobbin. The key mechanical movements are drafting (controlled speed differential between rollers to thin the roving), twisting (spindle rotation), and winding (bobbin movement to distribute yarn evenly).13

The spinning jenny (1764) and the water frame (1769) were the original multi-spindle designs. The mule (1779) combined features of both. These designs are well-documented in engineering history and are within NZ’s fabrication capability.

NZ fabrication requirements:

  • Steel spindles — precision turned on a lathe (Doc #91). Spindles must be straight, smooth, and well-balanced. This is the highest-precision component.
  • Drafting rollers — steel or leather-covered, precisely spaced
  • Frame — steel or timber
  • Flyer mechanism or ring-and-traveller (for continuous spinning) — machined steel components
  • Bobbin and spool turning — lathe work on timber or steel
  • Drive mechanism — belt-driven from electric motor, or direct drive

Complexity assessment: Moderate-to-high. A spinning frame is more mechanically complex than a carding machine because of the precision required in spindle alignment, drafting roller spacing, and the coordination of multiple movements. A prototype frame with 10–20 spindles could be built in a well-equipped machine shop in 4–8 weeks. Scaling to 50+ spindle frames requires additional development time.14

Throughput: A 50-spindle spinning frame operated by one person can produce approximately 20–100 kg of yarn per day depending on yarn count (thickness) and fiber type.15 Ten such frames could produce 50–250 tonnes of yarn per month.

2.3 Looms

Hand looms (floor looms):

Floor looms are fundamentally timber structures requiring seasoned hardwood (beech, rimu, or similar), basic woodworking tools (saw, plane, drill, chisel), metal hardware (bolts, hinges, and ratchet pawls — from existing stocks or fabricated by a blacksmith), heddles (drawn steel wire loops, sourced from existing stock or wire-drawn — Doc #105), and a reed (fine steel wire soldered into a frame). A competent woodworker with these materials and published plans can build a production-quality 4-shaft floor loom in 2–4 weeks. Machine shop involvement is not required for the timber frame, but the heddles and reed require wire-working capability.16

Floor looms produce 1–3 metres of fabric per day per weaver, depending on weave complexity and fabric width.17 This is adequate for initial production but insufficient for national-scale needs.

Power looms:

Power looms mechanise the weaving process: shedding (separating warp threads to create a gap), picking (throwing the weft thread through the gap), and beating (pushing the weft thread into position). These three movements must be precisely coordinated at speed.18

NZ fabrication requirements:

  • Steel and timber frame
  • Cam or dobby mechanism for shedding — machined steel cams, levers, and linkages
  • Shuttle or rapier mechanism for picking — the shuttle (traditional) is a weighted block thrown through the shed; the rapier (modern) is a mechanical arm that carries the weft thread. Shuttle looms are simpler to build; rapier looms produce less noise and allow more weft variety.
  • Reed (the comb-like component that beats weft into position and spaces warp threads) — drawn steel wire, soldered or welded into a frame. Reeds must be precise — irregular spacing produces uneven fabric.
  • Heddles (the loops that lift and lower individual warp threads) — drawn steel wire, formed into loops. Thousands per loom.
  • Warp beam, cloth beam, and associated rollers — turned steel or timber
  • Drive mechanism — electric motor with belt or gear drive

Complexity assessment: High. A power loom is among the more complex machines in the pre-electronic manufacturing toolkit. The coordination of shedding, picking, and beating at 60–200 picks per minute requires precise timing. NZ’s first recovery-era power looms will be slow (30–60 picks per minute) and narrow (60–120 cm), improving with experience. Building the first prototype power loom is a 3–6 month machine shop project. Subsequent units are faster as designs are refined.19

Throughput: A power loom at 60 picks per minute produces approximately 10–30 metres of fabric per day, depending on fabric width and weft density.20 One hundred power looms could produce 250,000–750,000 metres per year — enough for several million garments.

2.4 Knitting and sewing machines

Domestic knitting machines exist in NZ in significant numbers — estimated thousands in private homes, many unused.21 These produce fabric 5–10 times faster than hand knitting. Locating them through the asset census and deploying them is an immediate priority. Industrial knitting machines are more complex — the hardest component is precision needle manufacturing (fine hardened steel hooks, 0.5–1.5 mm diameter, thousands per machine). Building industrial knitting machines is a Phase 3–4 project. Importing knitting machine needles via trade (small, lightweight, high-value) while building machines domestically may be the most practical path.22

Sewing machines — NZ has an estimated 200,000–600,000 domestic machines.23 These are adequate for garment assembly. Industrial sewing machines exist in small numbers and should be secured. The consumable constraint is needles — precision steel components that break or dull. NZ can produce them (Doc #105 for wire drawing capability; Doc #91 for machine shop tooling) but this requires fine hardened steel wire drawing and dedicated forming and pointing jigs. Existing needle stocks should be inventoried and rationed.24

3. THE SKILLS PIPELINE

3.1 Existing skill holders

NZ has more textile skill than most modern industrialised countries, concentrated in three communities:

Craft community: Weavers, Spinners and Woolcrafts NZ represents local guilds throughout the country. These guilds hold equipment (floor looms, spinning wheels, drum carders), skills, and institutional knowledge. The community is predominantly female and skews older — many members are retired. Their knowledge is the training foundation for recovery-era textile production.25

Maori weaving community: Kairaranga (weavers) who practice traditional harakeke processing and weaving. The National Maori Weavers Collective holds collective knowledge. Integration should follow the partnership model described in Doc #160 (Heritage Skills Preservation), Section 6.26

Ashford Handicrafts workforce: The Ashford factory in Ashburton employs workers with manufacturing knowledge of textile equipment production. This workforce is critical — they know how to build spinning wheels and looms. Under recovery conditions, they transition from craft-market production to industrial-scale equipment manufacturing.27

3.2 Training timeline and structure

Training times to production quality vary: hand spinning (wheel) 1–3 months; hand knitting 2–4 weeks; hand weaving (floor loom) 3–6 months; power loom operation 1–3 months; garment pattern-making 1–2 years; cobbling 1–3 years; vegetable tanning 6–12 months.28 These ranges reflect structured training under experienced practitioners; informal self-teaching will take longer and may not reach production quality. Shorter-duration skills (spinning, knitting) can be taught through guild instruction and peer learning. Longer-duration skills (pattern-making, cobbling, tanning) require formal apprenticeships integrated into Doc #157 (trade training) and Doc #160 (heritage skills).

Key constraint: The instructors are the bottleneck, not the learners. NZ has perhaps a few hundred experienced spinners, weavers, and textile practitioners who can teach at production quality. Training the trainers (second-generation instructors) expands capacity but takes 1–2 years.

Targets: Year 1: 5,000–10,000 hand-spinners, 1,000–2,000 hand-weavers. Year 2–3: 500–1,000 machine operators as equipment comes online. Ongoing: apprenticeships in pattern-making, tailoring, cobbling, tanning, and dyeing.

4. REGIONAL TEXTILE PROCESSING CENTRES

4.1 Concept

The production model is regional processing centres located near wool supply and population centres, each integrating the full processing chain from raw wool to finished goods. This replicates (on a smaller scale) the historical NZ woollen mill model.

High-priority centres (near wool supply and population): Waikato (Hamilton), Hawke’s Bay (near Cavalier scouring at Awatoto), Canterbury (Ashford Handicrafts at Ashburton, Lincoln research facilities), Manawatu (Palmerston North — wool processing history, Massey University), Bay of Plenty (Tauranga — port, population, climate). Moderate-priority centres in Otago (Dunedin — Mosgiel historical site), Southland, Wanganui (historical milling tradition), Wellington, Taranaki, and Northland.

4.3 Facility requirements per centre

Each centre requires approximately 1,300–2,700 m2 covering scouring, carding, spinning, weaving/knitting, finishing (fulling and dyeing), garment assembly, and storage.29 These floor area estimates are derived from the equipment footprints described in Section 2, plus clearance, passage, and storage space; they are indicative and should be verified against specific building plans during site selection. Staffing: 65–160 workers per centre (lower bound for hand-production configuration; upper bound includes machine operators as equipment comes online). Existing buildings — disused factories, large woolsheds, school halls — can be adapted; new construction is not required if suitable buildings are identified through the asset census.

Total workforce across 15 centres: 1,000–2,400 workers in processing centres, plus thousands more in community-level hand-production (home spinners, knitting circles, household sewing).

5. THE FULL PRODUCTION CHAIN: WOOL TO GARMENT

5.1 Dependency chain

Each step must function for the system to produce clothing. The chain from raw wool to finished garment runs: (1) shearing, (2) sorting, (3) scouring, (4) carding, (5) spinning, (6) weaving or knitting, (7) finishing, (8) cutting and sewing. Steps 1–3 use existing NZ capability.3031 Steps 4–6 must be built — these are the manufacturing gaps addressed in Section 2. Step 7 (fulling, dyeing, lanolising) requires only water, heat, mechanical action, and NZ plant dye sources.3233 Step 8 leverages NZ’s existing stock of hundreds of thousands of domestic sewing machines, supplemented by the trade training program (Doc #157) for pattern-making and garment construction skills.

5.2 Bottleneck analysis

Step Current capacity vs. need Bottleneck severity
Shearing Adequate None
Sorting Adequate None
Scouring Adequate (existing plants) None
Carding ~100x gap High — equipment must be built
Spinning ~1,000x gap Very high — largest equipment gap
Weaving/knitting ~100–1,000x gap Very high — equipment and skills
Finishing Buildable quickly Low
Garment assembly ~10x gap (domestic machines help) Moderate

The critical bottleneck is mid-chain: carding, spinning, and weaving/knitting equipment. This is where machine shop capacity (Doc #91) must be directed.

6. WHAT NZ CANNOT MAKE

Doc #36 (Section 2.5) covers NZ’s material gaps in detail. In summary, the following cannot be manufactured domestically and represent permanent constraints on garment design:

  • Elastic: Requires synthetic rubber or elastane. No NZ pathway. Adaptation: drawstrings, buttons, ties, knitted ribbing.34 These alternatives are functional but add bulk, require more adjustment, and are less comfortable for undergarments and activewear than elastic waistbands.
  • Zippers at scale: Requires precision stamping of interlocking teeth from brass or aluminium strip, plus slider fabrication — both beyond current NZ tooling. Adaptation: buttons, toggles, lacing. These are slower to fasten and less wind- and water-tight than zippers for outerwear. Salvage working zippers from worn-out garments.
  • Synthetic fabrics (polyester, nylon, acrylic): Requires petrochemical feedstocks. Adaptation: wool for all textile applications. Wool is heavier than synthetics, retains more water when wet (though it still insulates when damp, unlike cotton), degrades faster under UV exposure, and cannot match the abrasion resistance of nylon or the quick-drying properties of polyester. High-friction applications (pack straps, harnesses) will wear through wool fabric faster than synthetic equivalents.
  • Cotton: Cannot grow in NZ’s climate.35 Adaptation: fine merino wool (under 20 microns) for next-to-skin applications.36 Merino is warmer and more moisture-wicking than cotton but heavier, slower to dry when saturated, and less comfortable in warm weather. Summer-weight garments will be less breathable than cotton equivalents.
  • Rubber soles: Same constraint as tires (Doc #33). Adaptation: leather soles with hobnails (Doc #36, Section 7.4). Leather soles wear faster than rubber (months rather than years under heavy use), provide less shock absorption, and lose grip on wet or muddy surfaces. Hobnails improve grip on soft ground but damage indoor flooring and are slippery on hard wet surfaces such as concrete or steel.

NZ can manufacture substitutes for all other garment components: buttons from bone, horn, and shell (paua, mussel); thread from wool and muka; needles and pins from NZ steel (Doc #89); buckles from steel or copper. These are low-technology products suitable for community-level production.

7. SUPPLEMENTARY FIBERS AND PRODUCTION METHODS

7.1 Possum fur

NZ’s estimated 30 million brushtail possums produce exceptionally fine fiber (approximately 10–14 microns — finer than cashmere at approximately 14–16 microns), hollow-fibered and very soft.37 Possum-merino blends (20–40% possum, 60–80% merino) produce yarn warmer, lighter, and softer than pure wool — ideal for base layers, socks, and gloves. Yield per animal is small (approximately 100–200 grams of usable fiber, depending on pelt condition and processing method).38 At scale, NZ might harvest 500–3,000 tonnes per year through pest control operations, though this is highly uncertain — actual yield depends on the scale of coordinated trapping operations, pelt handling during the hunt, and processing losses.39 Possum fiber processes on the same carding and spinning equipment as wool but requires blending with a longer fiber (wool staple) because possum fiber is too short to spin alone at useful yarn counts.

7.2 Harakeke, linen, and loom-free production methods

Harakeke fiber (Doc #100) contributes sacking, canvas, outer garments, and blended textiles. It is not a next-to-skin fiber. True flax (Linum usitatissimum) could be trialed from Phase 3 onward for linen production — lightweight, breathable textile with different properties from wool.40

Harakeke also supports loom-free garment production through two techniques that are particularly valuable during the early transition when weaving equipment is scarce:41 whatu (finger weaving) produces cloaks, blankets, and outer garments from muka, wool, or mixed fiber without any loom — warps hang freely and wefts are woven by hand. Taniko (geometric border weaving) produces functional banding for cloaks, headbands, and belts. Both techniques are held by active kairaranga (weavers) through the National Maori Weavers Collective (Te Ropu Raranga Whatu o Aotearoa) and should be included in the training pipeline (Section 3) alongside Euro-derived spinning and weaving. Muka processing methods for extracting fine inner fiber from harakeke are covered in Doc #36 (Section 2.3) and Doc #100. Traditional Maori natural dye knowledge — using tanekaha bark for gold, coprosma berries for blue, lichen species for purple, and mud-based iron mordants for black — complements the NZ-source natural dyeing described in Doc #36 (Section 4.6).

8. CRITICAL UNCERTAINTIES

Uncertainty Impact Mitigation
Machine shop capacity allocation — textile equipment competes with dozens of other priorities (Doc #8) Determines how quickly industrial textile equipment is built Prioritisation within the national manufacturing plan. The economic case for textile equipment is strong (Section: Economic Justification).
Number of operational domestic knitting machines in NZ Could significantly accelerate garment production if identified and deployed quickly Identify through census (Doc #8). Redistribute to skilled operators or production centres.
Card clothing fabrication — fine wire production is the hardest component of carding machines Without card clothing, carding machines cannot function Trial fine wire drawing early. Import card clothing via trade if NZ fabrication proves inadequate.
Speed of training new spinners and weavers to production quality Determines when sufficient workforce exists Begin training in Year 1. Use every available experienced practitioner as an instructor.
Wool supply under nuclear winter — how much does the flock shrink? Determines raw material availability. Even at 50% of normal, wool supply is ample for clothing. Monitor through pastoral farming assessment (Doc #74).
Ashford Handicrafts — can it scale equipment production? This factory is NZ’s best-positioned textile equipment maker Assess capacity, workforce, materials. Provide resources to scale up. Prioritise as national asset.
Sewing machine needle supply — depletion timeline for existing stocks Without needles, sewing machines are useless Inventory needle stocks through census. Begin needle fabrication development (fine wire drawing and forming). Include needles as a trade priority.
Power loom development timeline — these are complex machines Determines when woven fabric production reaches meaningful scale Begin design work in Year 1. Build prototypes in Year 2–3. Accept that early looms will be slow and narrow.
Chrome tanning chemical depletion Limits production of soft leather for garment use and shoe uppers Transition to vegetable tanning. Accept stiffer leather.
Possum fur collection logistics Determines whether possum fiber contributes meaningfully or remains marginal Integrate with pest control operations. Establish collection and processing infrastructure.

FOOTNOTES

  1. NZ garment manufacturing decline: NZ’s clothing manufacturing sector contracted sharply from the 1980s onward following trade liberalisation. By the 2020s, domestic garment production served only niche premium markets. See: Belich, J., “Paradise Reforged: A History of the New Zealanders from the 1880s to the Year 2000,” Allen Lane, 2001. Also: Statistics NZ, Business Demographics data on manufacturing sector employment trends.↩︎

  2. The national asset census (Doc #8) should include textile manufacturing assets as a specific category. The volume and location of sewing machines, knitting machines, and textile equipment in NZ is currently unknown and must be established.↩︎

  3. Weavers, Spinners and Woolcrafts NZ: The national body for hand-weaving, spinning, and related textile crafts in NZ. Local guilds operate in most centres. https://woolcrafts.org.nz/ — These guilds collectively hold more textile production knowledge and equipment than any other NZ organisation.↩︎

  4. Ashford Handicrafts Ltd, Ashburton: NZ’s only manufacturer of spinning wheels, looms, and textile equipment. Founded 1934. Exports worldwide. Under recovery conditions, this factory becomes one of NZ’s most important manufacturing facilities. See: https://www.ashford.co.nz/ — Capacity and workforce figures should be verified directly through the national asset census.↩︎

  5. Spinning frame productivity: A multi-spindle spinning frame produces yarn at many times the rate of a hand spinner. The exact ratio depends on spindle count, spindle speed, and yarn weight. Historical data from 19th-century textile mills suggests 10–50x productivity improvement over hand spinning per worker. See: Catling, H., “The Spinning Mule,” David & Charles, Newton Abbot, 1970. Also: Hills, R.L., “Power in the Industrial Revolution,” Manchester University Press, 1970.↩︎

  6. Power loom productivity: A power loom produces fabric at approximately 10–50x the rate of a hand weaver, depending on the loom speed and fabric complexity. Early power looms (1790s–1820s) were approximately 3–7x faster than hand looms; later improved designs significantly exceeded this. See: Mann, J.A., “The Cotton Trade of Great Britain,” 1860 (reprinted). Also: Baines, E., “History of the Cotton Manufacture in Great Britain,” 1835.↩︎

  7. NZ woollen mill history: NZ had a significant woollen milling industry from the 1870s through the mid-20th century. Major mills included Mosgiel Woollens (est. 1871, Dunedin), Kaiapoi Woollen Manufacturing Company (est. 1878, Kaiapoi), and others. See: McLintock, A.H. (ed.), “An Encyclopaedia of New Zealand,” Government Printer, Wellington, 1966 — entries on woollen manufacturing. Also: Belich, J., “Paradise Reforged,” 2001.↩︎

  8. NZ textile manufacturing current state: NZ’s textile manufacturing sector as of the 2020s comprises a handful of small-scale operations. No industrial-scale wool-to-fabric manufacturing exists for the domestic market. See: Stats NZ, Business Demographics; Ministry of Business, Innovation and Employment (MBIE) sector reports.↩︎

  10. Carding machine design and throughput: Standard textile engineering reference. Carding is among the oldest mechanised textile processes, dating to the 18th century. Industrial carders process 50–200 kg/hour depending on size. See: Lord, P.R. and Mohamed, M.H., “Weaving: Conversion of Yarn to Fabric,” Woodhead Publishing, 2nd edition, 1982. Also: Klein, W., “The Technology of Short-Staple Spinning,” The Textile Institute, various editions.↩︎

  11. Card clothing fabrication: Card clothing (wire-toothed fabric covering the carding drums) was historically manufactured by specialised firms. The wire is fine (0.3–1.0 mm) and must be bent to a specific hook profile. This is a specialised but not impossibly difficult manufacturing process. See: Textile Research Journal, various papers on card clothing design and performance.↩︎

  12. Carding machine design and throughput: Standard textile engineering reference. Carding is among the oldest mechanised textile processes, dating to the 18th century. Industrial carders process 50–200 kg/hour depending on size. See: Lord, P.R. and Mohamed, M.H., “Weaving: Conversion of Yarn to Fabric,” Woodhead Publishing, 2nd edition, 1982. Also: Klein, W., “The Technology of Short-Staple Spinning,” The Textile Institute, various editions.↩︎

  13. Spinning frame design: The mule spinner and ring spinner are the two main industrial spinning technologies developed in the 18th–19th centuries. Both are well-documented. See: Catling, H., “The Spinning Mule,” 1970. Also: Marsden, R., “Cotton Spinning: Its Development, Principles, and Practice,” 1903 — though focused on cotton, the mechanical principles apply to wool spinning with modifications for the longer, coarser fiber.↩︎

  14. Spinning frame design: The mule spinner and ring spinner are the two main industrial spinning technologies developed in the 18th–19th centuries. Both are well-documented. See: Catling, H., “The Spinning Mule,” 1970.

Historical data from 19th-century textile mills suggests 10–50x productivity improvement over hand spinning per worker. See: Catling, H., “The Spinning Mule,” David & Charles, Newton Abbot, 1970. Also: Hills, R.L., “Power in the Industrial Revolution,” Manchester University Press, 1970.↩︎

  16. Floor loom design: Ashford Handicrafts (Ashburton) publishes loom plans and specifications. NZ Handweaving periodicals and guild publications contain practical loom-building guidance. See also: Chandler, D., “Learning to Weave,” Interweave Press, various editions.↩︎

  17. Floor loom throughput: A skilled weaver on a 4-shaft floor loom typically produces 1–3 metres of fabric per 8-hour day for plain weaves at standard widths (90–120 cm); complex weave structures and wide warps reduce this significantly. Based on practical guild and studio production records. See: Ashford Handicrafts technical documentation; also Guild of Weavers, Spinners and Dyers (UK), “The Craft of the Weaver,” various editions.↩︎

  18. Power loom productivity: A power loom produces fabric at approximately 10–50x the rate of a hand weaver, depending on the loom speed and fabric complexity. Early power looms (1790s–1820s) were approximately 3–7x faster than hand looms; later improved designs significantly exceeded this. See: Mann, J.A., “The Cotton Trade of Great Britain,” 1860 (reprinted). Also: Baines, E., “History of the Cotton Manufacture in Great Britain,” 1835.↩︎

  19. Power loom productivity: A power loom produces fabric at approximately 10–50x the rate of a hand weaver, depending on the loom speed and fabric complexity. Early power looms (1790s–1820s) were approximately 3–7x faster than hand looms; later improved designs significantly exceeded this. See: Mann, J.A., “The Cotton Trade of Great Britain,” 1860 (reprinted). Also: Baines, E., “History of the Cotton Manufacture in Great Britain,” 1835.↩︎

  20. Power loom throughput calculation: At 60 picks per minute and a sett of approximately 20 picks per centimetre (a medium-weight wool fabric), a loom weaving 90 cm width produces approximately 18 metres per hour of running time. Allowing for downtime (warp changes, maintenance, beam loading), 10–30 metres per working day is a realistic range for an early recovery-era shuttle loom. Production looms in the 19th century averaged higher rates as designs matured. See: Baines, E., “History of the Cotton Manufacture in Great Britain,” 1835; Mann, J.A., “The Cotton Trade of Great Britain,” 1860 (reprinted).↩︎

  21. Domestic knitting machine prevalence in NZ: Exact numbers are not available from public sources. The estimate of “thousands” is based on the popularity of machine knitting as a hobby in NZ from the 1970s through 1990s, with many machines now in storage. The skills census (Doc #8) would establish the actual number. See: NZ Machine Knitters’ Association records.↩︎

  22. Knitting machine needle manufacture: Knitting machine needles (latch needles or bearded needles) are precision steel components requiring hardened, tempered wire and precise forming. They are among the most demanding small-scale steel products to manufacture. See: Spencer, D.J., “Knitting Technology,” Woodhead Publishing, 3rd edition, 2001.↩︎

  23. NZ sewing machine stock: NZ’s stock of domestic sewing machines is large but unquantified. Based on household ownership surveys in comparable countries (10–30% of households owning a sewing machine) and NZ’s approximately 2 million households, the total is likely in the range of 200,000–600,000 machines. This figure is uncertain and should be established through the census.↩︎

  24. Sewing machine needle manufacturing: Needles are drawn from hardened steel wire, formed, pointed, and polished. A sewing machine needle is approximately 38 mm long with a diameter of 0.6–1.2 mm. Manufacturing requires fine wire drawing, precision forming jigs, heat treatment, and quality control. This is within NZ machine shop capability but requires dedicated tooling development. See: Schmetz (needle manufacturer) technical publications.↩︎

Under recovery conditions, this factory becomes one of NZ’s most important manufacturing facilities. See: https://www.ashford.co.nz/ — Capacity and workforce figures should be verified directly through the national asset census.↩︎

  28. Textile training timelines: Ranges are based on practitioner experience documented in NZ guild publications and international textile training programmes. Hand-spinning to production quality: Weavers, Spinners and Woolcrafts NZ guild training records suggest 2–6 months for basic competence, 6–18 months for consistent production quality. Cobbling and tanning timelines are drawn from historic trade apprenticeship records (typically 3–7 years for a formal apprenticeship; 1–3 years for targeted recovery-era training focused on the most common operations). All timelines assume structured instruction; self-taught timelines will be longer.↩︎

  29. Regional textile centre floor areas: Estimates derived from equipment footprints in Section 2. Assumed equipment per medium-sized centre: 2–4 carding machines (approximately 3–6 m2 each, plus clearance), 4–8 spinning frames (approximately 4–8 m2 each), 10–20 looms (approximately 2–4 m2 each), scouring area (approximately 100–200 m2), finishing and dyeing (approximately 100–200 m2), garment assembly (100–200 m2), and storage (200–400 m2). These are indicative planning figures; actual requirements should be verified against specific equipment and building geometries during site selection.↩︎

  30. NZ wool production and types: Beef + Lamb New Zealand Economic Service, “Compendium of New Zealand Farm Facts,” various years. https://beeflambnz.com/ — NZ produced approximately 120,000–140,000 tonnes of greasy wool per year in the early 2020s. Fine merino (<20 microns) represents approximately 10% of production, primarily from South Island high country. Crossbred wool (24–35+ microns) is the majority.↩︎

  31. NZ wool scouring industry: NZ has several wool scouring plants. Cavalier Bremworth operated scouring at Awatoto (Hawke’s Bay). NZ Wool Services International has Canterbury facilities. The industry has consolidated but scouring capacity exists. See: Ministry for Primary Industries, NZ Wool Industry reports.↩︎

  32. Fulling: The process of wetting and agitating woven wool fabric to shrink and interlock the fibers, producing denser, more weather-resistant cloth. Fulling was one of the earliest mechanised textile processes — water-powered fulling mills date to the medieval period. See: Carus-Wilson, E.M., “An Industrial Revolution of the Thirteenth Century,” Economic History Review, 1941 — discusses the spread of fulling mills. The process requires only water, heat, and mechanical action.↩︎

  33. Natural dyes from NZ sources: Multiple NZ plants produce usable dyes. Tanekaha (Phyllocladus trichomanoides) for gold, coprosma berries for blue, lichen species for purple. Mordants (alum, iron, tannin) fix the dye to the fiber. See: Caldwell, M., “New Zealand Natural Dyeing,” Random House NZ, various editions. Also: traditional Maori dyeing knowledge, documented in ethnographic literature.↩︎

  34. Non-elastic garment closures: All clothing prior to the 20th century used non-elastic closures — buttons, ties, drawstrings, hooks, lacing. The adaptation is a return to historical garment design. See any historical costume reference, e.g.: Tortora, P.G. and Eubank, K., “Survey of Historic Costume,” Fairchild Publications, various editions.↩︎

  35. Cotton climate requirements: Cotton (Gossypium spp.) requires sustained temperatures above 20°C for 5–6 months. NZ’s temperate maritime climate does not meet these requirements. See: Constable, G.A. and Bange, M.P., “The Yield Potential of Cotton,” CSIRO, various publications on cotton agronomy.↩︎

  36. NZ wool production and types: Beef + Lamb New Zealand Economic Service, “Compendium of New Zealand Farm Facts,” various years. https://beeflambnz.com/ — NZ produced approximately 120,000–140,000 tonnes of greasy wool per year in the early 2020s. Fine merino (<20 microns) represents approximately 10% of production, primarily from South Island high country. Crossbred wool (24–35+ microns) is the majority.↩︎

  37. Possum population and fiber: Department of Conservation (DOC) estimates approximately 30 million brushtail possums in NZ. https://www.doc.govt.nz/ — Possum fiber yield approximately 100–200 grams per animal. Possum-merino blends are produced commercially by NZ companies including Untouched World and others, demonstrating the fiber’s quality. See: McRae, K.C., “Possum Fibre,” NZ Journal of Agricultural Research, various years.↩︎

  40. Flax (Linum usitatissimum) for linen: True flax is a temperate crop that can be grown in NZ. Experimental plantings have been made. Linen fiber is produced by retting and processing the flax stems. NZ has no existing linen processing infrastructure. See: Franck, R.R. (ed.), “Bast and Other Plant Fibres,” Woodhead Publishing, 2005. Also: NZ Institute for Crop and Food Research, trial reports.↩︎
