Doc #36 — Clothing and Footwear: From Import Dependence to Local Production

---

1. NZ’S CURRENT POSITION

1.1 Import dependence

NZ imports approximately NZ$3–4 billion worth of clothing, textiles, and footwear per year under normal conditions.¹ In volume terms, this represents tens of thousands of tonnes of finished garments, fabric, and shoes annually. Virtually none of the clothing sold in NZ is manufactured domestically — the supply chain runs through China, Bangladesh, Vietnam, India, and other low-cost manufacturing countries.

What NZ imports:

• Ready-made garments (shirts, trousers, dresses, jackets, etc.)
• Underwear, socks, and hosiery
• Footwear (casual, sports, work, fashion)
• Fabric and textiles (cotton, polyester, nylon, blends)
• Sewing notions (thread, zippers, elastic, buttons, fasteners)
• Synthetic fibers (polyester, nylon, acrylic)

What NZ produces domestically:

• Greasy wool (large volumes — NZ is a major global producer)
• Some scoured and processed wool (a diminished but existing industry)
• A small amount of high-end wool yarn and fabric (e.g., NZ Merino Company products, small craft yarn producers)
• Small quantities of premium garments from a handful of domestic manufacturers
• Sheepskins and some leather processing (limited)

1.2 The national clothing stock

NZ’s population of approximately 5.2 million people collectively owns an enormous volume of clothing.² Estimating the total is inherently uncertain, but some rough parameters:

• International surveys suggest the average person in developed countries owns 60–100+ garments.³ NZ is likely in this range.
• At 5.2 million people averaging 70 garments each, the national wardrobe contains roughly 350–400 million garments.
• Additionally, NZ has large volumes of unsold clothing in retail stores, warehouses, and distribution centres, plus significant stocks in charity shops (NZ has an active second-hand clothing culture through organisations like the Salvation Army, Red Cross shops, and Hospice shops).

Key point: This stock is not evenly distributed. Some people have far more than they need; others already have too little. Wealth and geography matter — rural workers need durable outdoor clothing; urban professionals may have abundant office wear but few practical garments. Any managed distribution system must account for this unevenness.

1.3 Footwear stock

Footwear is a separate and harder problem. The average person might own 5–15 pairs of shoes, but many are fashion items with limited practical durability.⁴ Work boots, gumboots, and outdoor footwear are the critical categories. NZ’s total footwear stock is perhaps 30–70 million pairs across the population, but the subset that is durable, practical, and suitable for the physical work that recovery demands is much smaller.

Footwear wears out mechanically — soles erode, uppers crack and tear, stitching fails. Unlike clothing, which can often be repaired with basic sewing, footwear repair requires specialised skills and materials (see Section 7).

1.4 Urgency calibration

Clothing is not an emergency. In the first weeks and months, nobody lacks clothing. The government should spend zero political capital on clothing in Phase 1. The focus should be on fuel, food, medicine, and public order — the actual emergencies.

The timeline for action:

Timeframe	Situation
Months 0–12	No shortage. Existing wardrobes are ample. Retail and charity stocks available.
Years 1–3	Some categories thinning — children’s clothing (growth), work clothing (wear), socks and underwear (high turnover items). Repair and redistribution become important.
Years 3–7	General shortage developing. Wool and leather production must be coming online. Imported synthetics wearing out and not replaceable.
Years 7–15	NZ must be producing most of its own clothing and footwear from domestic materials, or standards decline sharply.

The cost of delay is real but measured in years, not days. Starting wool textile development in Year 1 versus Year 3 affects whether NZ has adequate production by Year 5. But this is not a problem that demands action in the first 30 days, and treating it as one would distract from genuine emergencies.

2. RAW MATERIALS: WHAT NZ HAS

2.1 Wool — NZ’s primary textile advantage

NZ is one of the world’s largest wool-producing countries. The national flock of approximately 25–26 million sheep (as of the early 2020s — down from a peak of over 70 million in 1982) produces approximately 120,000–140,000 tonnes of greasy wool per year.⁵

NZ’s annual wool clip, if entirely converted to clothing, would provide many times more fiber than the population needs. Under normal conditions, the vast majority of NZ wool is exported — NZ consumes only a small fraction domestically. In a recovery scenario, all of this wool stays in NZ.

Wool properties relevant to clothing:

Property	Assessment
Warmth	Excellent — wool insulates even when wet, a significant advantage for NZ’s damp climate
Comfort	Good for most applications. Fine merino is comfortable next to skin. Coarser crossbred wool is better as outerwear.
Durability	Good. Wool fibers are naturally elastic and resist tearing.
Moisture management	Excellent. Wool absorbs moisture vapour without feeling wet, and dries relatively quickly.
Fire resistance	Good — wool is naturally fire-resistant and self-extinguishing.
Odour resistance	Good — wool resists bacterial growth that causes odour.
Dyeability	Excellent. Wool takes natural dyes well.

NZ wool types:

NZ produces several categories of wool with different properties:⁶

• Fine merino (under 20 microns): Approximately 10% of NZ production. Grown primarily in the South Island high country (Mackenzie Country, Central Otago). Suitable for next-to-skin garments — base layers, underwear, socks, fine knitwear. This is NZ’s most valuable wool for clothing.
• Medium crossbred (24–32 microns): The majority of NZ production. From Romney, Perendale, Coopworth, and Corriedale sheep. Suitable for mid-layer and outer garments — jumpers, trousers, jackets, blankets, heavy socks.
• Strong crossbred (over 32 microns): Coarser wool, traditionally used for carpet. Not comfortable next to skin but very durable. Suitable for outerwear, work clothing, blankets, upholstery, and industrial textiles (sacking, insulation).

Nuclear winter implications: Under nuclear winter conditions (5–8 degrees C cooling, reduced sunlight), pasture growth declines substantially, reducing sheep carrying capacity. Flock numbers will decrease. However, NZ will still have millions of sheep — wool production will decline but will not approach zero. Even at 50% of normal production (60,000–70,000 tonnes), the wool supply far exceeds domestic clothing needs. Wool production for clothing competes with wool for other uses (insulation, industrial textiles, export via trade), but the raw material constraint is manageable.

2.2 Leather — from existing hides

NZ processes approximately 5–6 million cattle and 25–30 million sheep per year under normal conditions.⁷ Each animal produces a hide or skin that can be tanned into leather. Under normal conditions, many NZ hides are exported raw or semi-processed to countries with larger tanning industries. In a recovery scenario, these hides stay in NZ.

Leather is the primary material for durable footwear. It is also used for belts, bags, gloves, aprons, and protective clothing.

NZ leather processing capability: NZ has some existing tanneries, though the domestic tanning industry has shrunk significantly.⁸ The skills and chemical processes for tanning are well-documented and can be rebuilt. The key inputs are:

• Hides/skins: Abundant from NZ’s pastoral farming.
• Tanning agents: Several options available in NZ (see Section 7.2 for detail).
• Tools and equipment: Tanning requires vats (timber or concrete, sized for full hides — a cattle hide vat needs approximately 1,000–2,000 litres capacity), fleshing knives (steel blades, sourced from existing stock or forged — Doc #89), drying racks (timber frame construction), and a beam (a large wooden or padded surface for fleshing and dehairing work). The equipment is constructable from NZ materials but a functional tannery takes weeks to set up and requires space, water supply, and drainage for the significant liquid waste produced.

2.3 Harakeke fiber (Doc #100)

Harakeke (Phormium tenax) is NZ’s native fiber crop and is covered in detail in Doc #100. Whole-leaf harakeke fiber is stiff and coarse, making it unsuitable for garments worn against the skin. However, the inner fiber (muka), extracted by stripping and scraping with a mussel shell, is substantially finer and was used to produce sophisticated clothing — cloaks (kakahu), rain capes (para), belts, and sandals (paraerae) — using whatu (finger weaving) techniques that require no loom.⁹ Experienced kairaranga (weavers) hold this knowledge today. Taniko, a geometric border weaving technique, produces decorative and functional banding applied to cloaks, headbands, and belts. Feather cloaks (kahu huruhuru), made by weaving feathers into a muka base, produce warm, water-shedding outer garments; the technique could be adapted for practical outerwear using readily available feathers (chicken, duck, goose). Skin cloaks (kahu kuri) — historically made from dog skin — use techniques for preparing and assembling skins into garments that are applicable to possum, rabbit, and sheep skins.

Harakeke also has a role in:

• Work aprons and protective clothing
• Sacking and bags for storing and transporting textile products
• Rope and cordage used in textile production
• Blended textiles where harakeke provides structure and wool provides comfort

Harakeke is a complement to wool, not a substitute for it, in the clothing context. See Doc #100 for the full fiber processing chain.

2.4 Other domestic fibers and materials

Possum fur: NZ has an estimated 30 million brushtail possums (Trichosurus vulpecula), an invasive pest.¹⁰ Possum fur is extremely fine (approximately 10–14 microns — finer than cashmere), hollow-fibered (excellent insulation), and very soft. A small NZ industry already blends possum fiber with merino wool to produce premium yarn. Under recovery conditions, possum trapping provides both pest control and a valuable fiber. The constraint is collection — possum fur must be harvested from trapped animals, and the yield per animal is small (approximately 100–200 grams of usable fiber).¹¹ At scale, this is a valuable supplement to wool for fine garments and insulation, but it cannot be the primary textile.

Rabbit fur and skins: NZ has a significant wild rabbit population, also an introduced pest. Rabbit skins can be used for fur garments, and rabbit fur can be felted or blended with wool.

Down feathers: NZ’s poultry and waterfowl (including farmed ducks and geese) produce down suitable for insulation in garments and bedding.

Plant fibers other than harakeke: Cabbage tree (Cordyline australis) fiber was used traditionally by Maori but is weaker and less versatile than harakeke. Not a significant clothing input.

Cotton: Cannot be grown in NZ’s climate. Cotton requires sustained temperatures above 20 degrees C for 5–6 months, which is not achievable in NZ, and certainly not under nuclear winter conditions.¹² NZ’s existing cotton clothing stock will wear out and cannot be replaced with domestic production. This is a genuine gap — cotton is lightweight, breathable, and comfortable for warm-weather wear. Wool can substitute for most cotton applications, but there is a real performance gap in warm conditions (though nuclear winter cooling reduces this issue for years).

Synthetic fibers (polyester, nylon, acrylic): Cannot be produced in NZ. These require petrochemical feedstocks and polymer manufacturing infrastructure that NZ does not have. Existing synthetic garments should be maintained and repaired as long as possible. When they wear out, they cannot be replaced. This transition from synthetic to natural-fiber clothing is permanent unless trade provides access to synthetics from larger industrial regions.

2.5 Materials NZ lacks

Material	Normally used for	NZ substitute	Performance gap
Cotton	Lightweight clothing, t-shirts, underwear, bed linen	Fine merino wool, harakeke	Wool is warmer (a disadvantage in summer), heavier; harakeke is coarse. Neither matches cotton for lightweight breathability.
Polyester	Blended fabrics, sportswear, fleece	Wool	Wool does not dry as quickly and is heavier. Wool fleece (felted) is functional but less convenient.
Nylon	Stockings, lightweight outerwear, waterproof shells	No direct substitute	No NZ-producible material matches nylon for lightweight water resistance. Oilskin (waxed fabric) provides water resistance but is heavier.
Elastic	Waistbands, underwear, socks	Drawstrings, buttons, ties, knitted ribbing	No NZ-producible elastic. Garment design must adapt.
Zippers	Closures on jackets, trousers, bags	Buttons (bone, wood, metal), toggles, ties, hook-and-eye	Functional but less convenient. Zipper repair extends existing stock.
Rubber (soles)	Footwear soles	Leather, wood, recycled rubber	Leather soles wear faster on hard surfaces. Wood is inflexible. Same constraint as tires (Doc #33).
Gore-Tex / waterproof membranes	Rain jackets, outdoor wear	Oilskin, waxed wool	Heavier, less breathable, requires re-treatment. Functional but a significant step down.

3. REPAIR AND REDISTRIBUTION — THE FIRST PRIORITY

3.1 Repair extends the existing stock by years

Before NZ builds a single new garment, the priority is to keep existing clothing and footwear functional as long as possible. Repair is the highest-value intervention in the first 3–5 years.

Clothing repair is among the more accessible manufacturing skills. Basic mending — patching holes, re-stitching seams, darning socks, replacing buttons — requires a needle, thread, and moderate practice. More people in NZ know basic sewing than know almost any other manufacturing skill, though competent darning and patching that produces durable repairs (as opposed to cosmetic fixes) takes some weeks of regular practice to learn.

Sewing machines: NZ has a large stock of domestic sewing machines — estimated hundreds of thousands in private homes, schools, and community groups. Most are electric; some are older treadle or hand-crank models. Electric machines continue to work under the baseline scenario (grid available). Industrial sewing machines are scarcer but exist in small manufacturing operations, alterations shops, and upholstery businesses. The national asset census (Doc #8) should identify these.

Thread: Sewing thread is an imported consumable. NZ’s stock of thread — in homes, haberdashery shops, and warehouses — is finite. This is a low-volume item but an essential one. Thread can be spun from wool (wool thread has been used for sewing for millennia) and from harakeke muka — finely processed muka makes strong sewing thread applicable to both traditional and European-style garment construction.¹³ Hand-spun wool or muka thread is functional for hand sewing, though it is weaker and less uniform than commercial polyester thread, breaks more easily under tension, and requires slower, more careful stitching. Machine sewing with hand-spun thread is more difficult — inconsistent thread diameter causes tension problems, jamming, and breakage — and may require machine adjustment or pre-selection of the most uniform thread lengths.

3.2 Redistribution

NZ’s existing clothing stock is unevenly distributed. Redistribution addresses this:

Charity and second-hand channels already exist. NZ has an established network of charity shops, clothing bins, and second-hand retail. These channels should be maintained and expanded. Under rationed conditions, they become a primary distribution mechanism.

Children’s clothing is the acute need. Adults’ wardrobes are effectively static — adults do not outgrow their clothes. Children do. A child may go through 2–3 sizes per year in early childhood. NZ’s stock of children’s clothing is large (families typically retain clothing through multiple children, and charity shops carry significant stocks), but it is the first category where supply-demand mismatch will appear. Community-level clothing exchanges for children should be established early.

Work clothing redistribution: Recovery demands more physical labour than modern NZ life. Many people’s wardrobes are weighted toward office and casual wear, not heavy outdoor work clothing. Redistribution of appropriate work clothing to those who need it — farm workers, construction crews, infrastructure maintenance teams — is a practical priority.

3.3 Adaptation and remaking

Garment alteration is an existing skill set. NZ has professional tailors and alterations specialists, though the number has declined. Altering existing garments — resizing, converting dress clothing to work clothing, adding reinforcement to worn areas — extends the useful stock.

Fabric from deconstructed garments. Large garments can be deconstructed to provide fabric for smaller ones. Worn-out garments can provide patches, insulation fill, and cleaning rags. Nothing should be discarded until it is genuinely beyond use.

4. WOOL TEXTILE PRODUCTION — THE CORE PATHWAY

4.1 The full processing chain

Converting raw wool into finished garments requires a series of processing steps. Each step requires equipment, skills, and supporting inputs. The chain is long but every step is well-understood and was historically performed in NZ.

Step 1: Shearing NZ has a large existing shearing workforce. Shearing continues under recovery conditions as part of normal sheep husbandry — sheep must be shorn annually for animal welfare regardless of whether the wool is processed.¹⁴ Electric shearing handpieces are the standard in NZ; they require electricity (available per baseline) and replacement combs and cutters (an imported consumable — existing stocks will deplete over years, after which hand-powered shears are needed). Hand blade shearing is slower but functional and requires no imports.

Step 2: Sorting and classing After shearing, wool is sorted by quality — fiber diameter, length, colour, contamination level. This is a skill held by wool classers, of whom NZ has many. Sorting determines which wool goes to which end use (fine garments, coarse outerwear, industrial applications).

Step 3: Scouring (washing) Greasy wool from the sheep contains lanolin (wool grease — approximately 10–25% of greasy weight), suint (sheep sweat salts), and dirt. Scouring removes these. NZ has existing wool scouring plants — Cavalier Bremworth’s plant at Awatoto (Hawke’s Bay) and other facilities.¹⁵ Industrial scouring uses hot water and detergent in a series of bowls. At smaller scale, scouring can be done with hot water alone, or with soap (Doc #37).

By-product: Lanolin recovered during scouring is a valuable material — a high-quality natural grease usable as a lubricant (Doc #34), skin treatment, leather conditioner, and water-resistance treatment for wool fabric (see Section 4.7).

Step 4: Carding Carded wool has its fibers opened, cleaned of remaining vegetable matter, and aligned into a loose web or roving. NZ has some existing carding machinery in small-scale wool processing operations. Hand carders (paddle-shaped tools with wire teeth) are used by craft spinners and are effective for small quantities. Drum carders (hand-cranked or motorised) process larger quantities. Building carding machines is within NZ’s fabrication capability — they are rotating drums covered in card clothing (fine wire teeth set in a leather or fabric backing). The wire must be drawn to a consistent fine gauge (Doc #52), and the card clothing must be mounted evenly on the drum surface. This is achievable in a well-equipped machine shop (Doc #91) but is not trivial — poorly made card clothing produces uneven roving and breaks fibers.

Step 5: Spinning Spinning draws out the carded roving and twists it into yarn. This is the step where NZ’s industrial capacity is thinnest. Options:

• Hand spinning (drop spindle): Requires only a stick and a weight. Slow — approximately 15–80 grams per hour for a skilled spinner, depending on fiber preparation and yarn weight (thicker yarn is faster).¹⁶ Sufficient for individual and household production. Drop spindles can be made from any wood and a small weight.
• Spinning wheel: Faster — approximately 50–200 grams per hour depending on wheel design, yarn weight, and spinner skill.¹⁷ NZ has thousands of spinning wheels in private hands (hand-spinning is an active craft community in NZ).¹⁸ Spinning wheels can be built from wood by a competent woodworker, though a functional wheel requires accurate alignment of the flyer, bobbin, and drive wheel — rough carpentry produces a wheel that binds or produces uneven yarn.
• Industrial spinning frames: Multi-spindle machines that produce yarn at many times the rate of a hand spinner. NZ has very few of these. Building them is feasible but non-trivial — while the basic principles date to the 18th–19th century, a functional spinning frame requires precision-machined spindles, bobbins, and rollers with consistent diameters and smooth bearings; a drive mechanism (belt or gear train); and careful alignment across all spindles so that yarn tension and twist rate are uniform. This requires machine shop capability (Doc #91), precision fabrication (Doc #91), and months of design, construction, and commissioning time per frame.

Step 6: Weaving or knitting

Weaving produces fabric from yarn on a loom. Fabric is then cut and sewn into garments.

• Backstrap and frame looms: Simple, portable, slow. Suitable for individual and household production. Can be built from wood.
• Floor looms (4-shaft, 8-shaft): Faster, produce more complex fabrics. NZ has an active hand-weaving community with floor looms in private and institutional use. New looms can be built by woodworkers.
• Power looms: Industrial-scale fabric production. NZ has very few operational textile power looms. Building them is feasible but requires significant engineering effort — power looms are more mechanically complex than spinning frames, involving multiple coordinated movements (shedding, picking, beating) at speed. This is a Phase 3–4 development.

Knitting produces fabric directly from yarn using needles or a knitting machine.

• Hand knitting: NZ has a large knitting community and extensive stocks of knitting needles. Hand knitting is slow (a jumper takes 30–80 hours depending on size, pattern complexity, and yarn weight)¹⁹ but requires no infrastructure. Knitting produces excellent garments — jumpers, socks, hats, gloves, scarves — and is well-suited to wool.
• Domestic knitting machines: NZ has thousands of domestic knitting machines (often unused, in storage). These produce fabric 5–10 times faster than hand knitting.²⁰ They should be identified through the asset census and redistributed to production centres.
• Industrial knitting machines: Very few in NZ. Would need to be built or imported via trade. A long-term goal.

Step 7: Fulling and finishing Woven or knitted wool fabric can be finished in several ways:

• Fulling (felting): Wetting and agitating woven wool fabric shrinks it and interlocks the fibers, producing a denser, windproof, more durable fabric. This is how traditional broadcloth, melton, and duffle fabric were made. The process requires only water, heat, and mechanical action (historically, human feet or water-powered fulling mills). Fulled wool fabric is an excellent material for outerwear — warm, wind-resistant, and naturally somewhat water-repellent.
• Napping: Raising the surface fibers of woven fabric to create a soft, insulating surface. Done by hand with teasel heads or wire brushes.
• Lanolising: Treating finished wool garments or fabric with lanolin to restore water resistance. Lanolin-treated wool sheds light rain effectively — this is how traditional fishermen’s ganseys (sweaters) and oilskins functioned.

Step 8: Cutting and sewing Cutting fabric and sewing garments requires patterns, cutting tools, and sewing capability (see Section 3.1 on sewing machines). Pattern-making and garment construction are skills held by fashion designers, dressmakers, and tailors — NZ has these, though the number has declined. Garment construction training should be part of the trade training program (Doc #156).

4.2 Dependency chain summary

Step	Equipment needed	Skills needed	Key consumables	NZ status
Shearing	Handpieces or blade shears	Shearers (existing workforce)	Combs/cutters (finite imported stock), then blade shears	Strong
Sorting	None	Wool classers (existing)	None	Strong
Scouring	Scour plant or vats + hot water	Scour operators	Detergent or soap (Doc #37)	Existing plants; scalable
Carding	Carders (hand, drum, or machine)	Moderate skill	Wire for card clothing	Weak at scale; buildable
Spinning	Spindles, wheels, or frames	Spinners	None significant	Weak at scale; large craft community
Weaving	Looms (various)	Weavers	None significant	Weak at scale; active craft community
Knitting	Needles or machines	Knitters (widespread)	Needles (metal — durable, long-lasting)	Strong for hand; moderate for machine
Finishing	Fulling stocks, teasels	Moderate skill	Water, heat	Buildable
Garment making	Sewing machines, scissors, patterns	Sewers, tailors	Thread (can be spun from wool)	Moderate — many home sewers

4.3 The bottleneck: mid-chain processing at scale

NZ has plenty of raw wool (Step 1–2) and plenty of people who can sew (Step 8). The bottleneck is in the middle: carding, spinning, and weaving/knitting at industrial scale. NZ’s existing capability at these steps is mostly artisan-level — hundreds or low thousands of craft practitioners producing for the hobby market. Converting this to production-level output requires either:

1. Training many thousands of people to spin and weave/knit by hand (labour-intensive but achievable — these are learnable skills with low equipment requirements), or

2. Building industrial spinning and weaving/knitting machinery (higher throughput per worker but requires months to years of machine shop effort), or

3. Both in parallel — which is the recommended approach.

4.4 Production estimates

Hand production pathway:

• One skilled hand-knitter can produce approximately 4–8 heavy jumpers per year, or 10–20 pairs of socks, or equivalent garments.²¹
• One skilled hand-spinner on a spinning wheel produces approximately 0.5–2 kg of yarn per week, depending on yarn weight and hours worked.²²
• One hand-weaver on a floor loom can produce approximately 0.5–2 metres of fabric per day (depending on fabric width, complexity, and weave structure).²³

To clothe NZ’s population requires, very roughly, 3–8 kg of finished wool products per person per year (this is an order-of-magnitude estimate — actual requirements depend on climate, activity level, garment durability, and how much existing clothing remains serviceable; the lower end assumes mild replacement needs, the upper end assumes full wardrobe provision).²⁴ For 5.2 million people, that is roughly 15,000–42,000 tonnes of finished wool products — well within NZ’s raw wool production capacity, but requiring enormous processing throughput.

By hand alone: If each knitter/weaver produces an average of 2 kg per week of finished goods (a more conservative estimate reflecting realistic hand production rates), producing 30,000 tonnes per year requires approximately 290,000 full-time textile workers — roughly 9–10% of NZ’s labour force of approximately 3.0–3.2 million.^{25 26} This is a large commitment, though historical pre-industrial societies routinely devoted comparable fractions of their labour to textile production.

With machinery: Even modest mechanisation (domestic knitting machines, small spinning frames, power looms) can increase per-worker output by 5–50 times, reducing the required workforce to perhaps 10,000–50,000 workers. This is a more sustainable allocation but requires building the machines first.

Realistic trajectory: NZ will not reach full self-sufficiency in Year 1. The transition is gradual — existing clothing stocks cover Years 1–3 while production capability scales up. By Year 5, NZ should aim for domestic production meeting at least basic needs (underwear, socks, work clothing). By Year 10, the majority of clothing should be domestically produced.

4.5 Felting — a shortcut for some applications

Felt is produced by matting wool fibers together through heat, moisture, and pressure, without spinning or weaving. This skips the spinning and weaving steps entirely.

Applications: Hats, boot liners, insoles, insulation, blankets, protective pads, industrial applications.

Advantages: Much simpler production chain than woven textiles. Requires only raw wool, hot water, and labour. Can be produced at household or community scale with no equipment.

Limitations: Felt cannot be used for tailored garments that require drape and flexibility. It is dense and rigid compared to woven or knitted fabric. It works for specific applications, not as a general-purpose textile.

Assessment: Felting should be actively promoted as an early-phase production method for items like blankets, hats, insoles, and insulation. It delivers useful products with minimal infrastructure.

4.6 Dyeing

Undyed wool ranges from white through cream, grey, brown, to black depending on sheep breed. Many garments can be produced in natural wool colours. For coloured textiles:

Natural dyes from NZ sources:

• Tanekaha bark (Phyllocladus trichomanoides): Yellow to gold
• Coprosma berries: Blue
• Onion skins: Orange to yellow
• Walnut husks: Brown
• Iron-stained mud: Grey to black
• Lichen (Pseudocyphellaria spp.): Purple to maroon

Mordants (fixatives to make dyes colourfast) can be sourced locally: alum from volcanic deposits, iron from rust water, tannin from bark. Chromium and tin mordants (used in modern dyeing) are not locally available and cannot be produced easily.

Natural dyeing produces a different colour palette than synthetic dyes — muted, earthy tones rather than bright colours. This is a genuine aesthetic difference that some will find limiting. The colours are attractive but the range is narrow compared to what NZ is accustomed to.

4.7 Waterproofing wool

NZ’s climate is wet. Water-resistant clothing is a practical necessity. Without synthetic waterproof membranes:

Lanolised wool: Knitted or woven wool treated with lanolin (recovered from scouring — see Step 3) is naturally water-resistant. Traditional fishermen’s ganseys relied on this. The treatment is simple: dissolving lanolin in warm water and soaking the garment. It must be re-applied periodically.

Oilskin: Woven fabric (wool or harakeke canvas) treated with linseed oil or tallow-based wax. NZ can produce linseed oil (from linseed/flax crops — Linum usitatissimum, which can be grown in NZ, though it is not currently cultivated at scale) and tallow (abundant from animal processing). Oilskin is heavy and stiff but effectively waterproof. The traditional NZ bush shirt and oilskin coat are historical precedents.

Fulled wool: Tightly fulled (felted) broadcloth resists water penetration and was the standard material for overcoats and cloaks for centuries before synthetic fabrics.

Performance gap: None of these match Gore-Tex or modern synthetic waterproof-breathable fabrics for comfort or weight. The substitution is functional — people stayed dry in wool and oilskin for thousands of years — but it is genuinely worse. Garments are heavier, less breathable, and require more maintenance.

5. KNITTING — NZ’S FASTEST PATHWAY TO GARMENT PRODUCTION

5.1 Why knitting matters

Of all the textile production methods, knitting offers the fastest path to finished garments from NZ wool:

• Skills are widespread. Tens of thousands of New Zealanders already know how to knit. Many more can be taught quickly — basic knitting is learnable in hours, competent garment production in weeks.
• Equipment is minimal. Knitting needles are durable, widely distributed, and can be made from wood, metal, or bone.
• Knitted garments from wool are excellent for NZ conditions. Jumpers, cardigans, socks, hats, gloves, scarves — all the items that will be in shortest supply — are naturally suited to knitting.
• Machine knitting multiplies output. The thousands of domestic knitting machines in NZ households represent immediate capacity if identified and deployed.
• No intermediate fabric step. Knitting goes directly from yarn to garment, skipping the weaving and cutting stages required for woven garments.

5.2 Priority knitted items

Item	Urgency	Reason
Socks	High	High wear rate; existing stocks deplete within 2–4 years. Wool socks are excellent.
Underwear (wool)	High	High wear rate. Merino wool underwear is comfortable and functional.
Jumpers/sweaters	Moderate	Existing stocks last years, but eventual replacement needed. Knitted jumpers are the natural NZ wool garment.
Hats and gloves	Moderate–High	Important under nuclear winter cooling. Quick to produce.
Scarves and neck warmers	Low–Moderate	Useful but less critical. Good training projects.
Baby clothing	High	Babies outgrow clothing rapidly. Knitting is well-suited to baby garments.

5.3 Organised knitting production

Community knitting circles — organised groups producing garments for distribution — are a practical model. This was done at massive scale during both World Wars, when volunteer knitting produced millions of socks, scarves, and garments for military personnel.²⁷ The model works because:

• Knitting is social and can be combined with other activities (childcare, meetings, storytelling)
• Quality control is achievable through group oversight
• Distribution can be managed locally
• Training happens naturally within the group

---

6. WEAVING — BUILDING INDUSTRIAL TEXTILE CAPACITY

6.1 Why weaving is necessary

Knitting produces excellent garments but cannot produce all textile products efficiently. Woven fabric is needed for:

• Trousers and tailored outerwear (woven fabric holds its shape better than knit)
• Blankets at scale
• Heavy work clothing
• Canvas and tarpaulins (from harakeke or coarse wool — see Doc #100)
• Upholstery and furnishing fabric

6.2 NZ’s weaving capability

NZ has an active hand-weaving community, primarily in the craft sector. The Weavers, Spinners and Woolcrafts NZ national body represents local guilds throughout the country. These guilds hold equipment (floor looms, spinning wheels), skills, and institutional knowledge.²⁸

The transition from craft weaving to production weaving requires:

• More looms. Floor looms can be built from timber by competent woodworkers. Designs are well-documented. A production-quality floor loom might take a skilled woodworker 2–4 weeks to build, assuming seasoned timber and basic woodworking tools are available.²⁹
• More weavers. Training takes months — a competent weaver can be trained in 3–6 months of dedicated practice. Experienced weavers from the craft community are the trainers.
• Larger looms for wider fabric. Domestic craft looms are typically 60–120 cm wide. Fabric for garment production benefits from wider widths (120–150 cm). Wider looms can be built but are more complex.

6.3 Power looms — Phase 3–4 development

Power looms (mechanically driven, requiring an electric motor or water wheel) increase output by roughly 10–50 times over hand weaving. Building power looms requires:

• Steel frame and mechanism components (Doc #89, Doc #91)
• Shuttle or rapier mechanism for weft insertion
• Reed, heddles, and beams (metal and timber components)
• Precision engineering — tolerances matter for consistent fabric production
• An electric motor or other power source

Historical context: NZ had wool mills operating power looms in the 19th and early 20th centuries — Mosgiel Woollens, Kaiapoi Woollen Manufacturing, and others.³⁰ The technology is within NZ’s capability to rebuild, though it will take years of machine shop development. Surviving equipment from NZ’s woollen mills — if any remains in museums or storage — would be valuable as reference or even for refurbishment.

Assessment: Power loom construction is a Phase 3–4 project. Hand weaving covers early needs; power weaving scales the industry.

7. FOOTWEAR — THE HARDER PROBLEM

7.1 Why footwear is harder than clothing

Footwear is more technically demanding than clothing because:

• Mechanical stress is higher. Shoes bear the wearer’s full body weight and endure continuous abrasion against hard surfaces.
• Sole materials are the binding constraint. Modern shoe soles are synthetic rubber or polyurethane — materials NZ cannot produce. Leather soles are functional but wear much faster on modern paved surfaces than rubber soles do.
• Construction requires specialised skills. Shoemaking (cobbling) is a distinct trade from garment making, requiring different tools and techniques.
• Fit is critical. Poorly fitting footwear causes injury, blisters, and reduced work capacity — a serious problem when physical labour is essential.

7.2 Leather production — the full chain

Leather for footwear (and other uses) requires tanning raw hides. The full dependency chain:

Step 1: Hide procurement Raw hides from cattle, sheep, goat, and deer processed at meatworks. Hides must be salted or processed within hours of slaughter to prevent bacterial decay. Under recovery conditions, NZ’s existing meatworks continue operating (they process animals for food; hides are a by-product).

Step 2: Preparation

• Soaking (rehydration of salted hides)
• Liming (soaking in lime solution to loosen hair and flesh — lime is available from NZ limestone deposits, several quarries operational)
• Fleshing (removing remaining flesh and fat — by hand with a fleshing knife, or by machine)
• Dehairing (scraping or chemical removal of hair)
• Bating (treating with enzymes to soften — historically done with animal dung or pigeon droppings; modern bating uses commercial enzymes, which are an imported consumable)

Step 3: Tanning Converting prepared hide to leather by chemical stabilisation of the collagen protein.

Vegetable tanning: The traditional method, and the most feasible for NZ. Uses tannin extracted from bark. NZ-available tannin sources:³¹

• Black wattle bark (Acacia mearnsii): Widely planted in NZ as a forestry tree. Excellent tannin source — this species is one of the world’s primary commercial tannin sources. NZ has significant black wattle stands.
• Manuka bark (Leptospermum scoparium): Contains tannin. Abundant throughout NZ.
• Radiata pine bark (Pinus radiata): NZ’s most abundant timber tree. Bark contains tannin, though at lower concentration than wattle.
• Tanekaha bark (Phyllocladus trichomanoides): Traditional Maori tanning agent.

Vegetable tanning takes weeks to months (bark liquor gradually penetrates the hide). It produces firm, stiff leather well-suited to shoe soles and heavy-duty applications. The process is slow but requires only bark, water, and time.

Chrome tanning: The modern industrial method, producing softer, more flexible leather (used for shoe uppers, garments, etc.). Requires chromium sulfate — an imported chemical. NZ has no domestic chromium source.³² Existing stocks of chrome tanning chemicals will deplete. Chrome tanning is not viable long-term without trade.

Oil tanning (chamois): Uses fish oil or other animal fats to produce soft, washable leather. Feasible in NZ using fish oil from the fishing industry. Produces a soft leather suitable for gloves, cleaning cloths, and light garments, but not structural enough for footwear.

Brain tanning: Traditional method using animal brains as the tanning agent. Produces soft, supple leather (buckskin). Feasible but labour-intensive — each hide requires hours of manual working (stretching and smoking) to achieve suppleness. Each animal’s brain contains roughly enough tanning agent for its own hide — a convenient natural ratio. Brain-tanned leather is less water-resistant than chrome-tanned leather and stiffens if it gets wet and is not re-worked while drying. Suitable for clothing leather and moccasin-style footwear, but not for applications requiring dimensional stability or prolonged wet exposure.

Step 4: Finishing After tanning: drying, oiling/greasing (to maintain suppleness), possibly dyeing, and cutting for end use.

7.3 Shoe construction

Leather shoe construction methods feasible in NZ:

Welted construction: The traditional method for quality footwear. A leather welt (strip) is stitched to the upper and insole, and the outer sole is then stitched to the welt. This produces a shoe that can be resoled repeatedly — the upper outlasts multiple soles. Welted construction requires awls, wax thread (linen or hemp thread waxed with beeswax or tallow), lasts (foot-shaped forms), and skill. It is slow (a skilled cobbler produces 1–3 pairs per day) but produces excellent, repairable footwear.³³

Pegged or nailed construction: Sole attached with wooden pegs or metal nails. Simpler than welting. Historically common for work boots. Less watertight than welted construction but functional and faster to produce.

Moccasin construction: A single piece of leather wraps under the foot and up the sides, with a vamp (top piece) sewn on. Simple, quick, and uses less leather than formal shoe construction. Good for indoor wear and light outdoor use. Not durable enough for heavy work on hard surfaces.

7.4 The sole problem

The most difficult aspect of footwear production is soles. Modern shoe soles are synthetic rubber or polyurethane — the same constraint as tires (Doc #33). NZ cannot produce these materials.

Leather soles: The traditional material. Firm vegetable-tanned cowhide makes a functional sole. Limitations:

• Wear rate: Leather soles wear through significantly faster than rubber on paved surfaces. On concrete or asphalt, a leather sole might last 2–6 months of heavy daily use; a rubber sole lasts 1–3 years under comparable conditions.³⁴ This means much higher replacement frequency — potentially 2–6 resoles per year for workers on hard surfaces.
• Water resistance: Leather soles absorb water and become soft and slippery when wet. This is a real problem in NZ’s rainy climate. Treatments help (tallow, beeswax) but do not solve it.
• Grip: Leather on wet surfaces is poor. This matters for farm work, outdoor work, and NZ’s generally damp conditions.

Wooden soles (clogs): Historically common in Europe. Wood is durable and waterproof. Clogs are noisy, rigid, and unsuitable for uneven terrain but functional for workshop and indoor use. NZ timber is available. Clog-making is a skill that would need to be learned — it has no NZ tradition.

Recycled rubber soles: If crumb rubber from tire recycling can be bonded into sheet material (see Doc #33, Section 5.1), this could provide sole material. The feasibility is uncertain and depends on the binder — but even limited recycled rubber sole production would be valuable, as soles are the highest-stress component.

Hobnails: Steel studs or nails driven into leather soles to reduce wear and improve grip. NZ can produce these (blacksmithing or machine shop). Hobnailed leather soles were standard for work boots through the early 20th century. They extend sole life significantly and improve grip on soft and uneven surfaces, though they damage indoor floors and are noisy on hard surfaces.³⁵

Combined approach: The realistic solution is leather soles with hobnails for outdoor work boots, and leather or recycled rubber soles for other footwear. This is functional but does not match the durability of modern rubber soles.

7.5 Gumboots

Gumboots (rubber Wellington boots) are ubiquitous in rural NZ and essential for farming — standing in mud, milking sheds, wet paddocks. NZ cannot produce rubber gumboots domestically.

Existing stock: NZ has a large stock of gumboots. They are durable — a quality pair lasts years. Managed carefully, the existing stock provides coverage for several years.

Substitution: There is no equivalent substitute for a rubber gumboot. Oiled leather boots provide some water resistance but are not comparable to rubber for standing in wet conditions. Wooden pattens (elevated wooden soles worn over shoes) were a historical solution for muddy conditions but are clumsy.

Trade priority: Rubber for gumboot production (or finished gumboots) should be a trade priority once maritime connections are established with rubber-producing regions. This is a case where trade genuinely matters — the local substitute is poor.

7.6 Cobbling skills

Shoemaking and shoe repair (cobbling) is a trade with very few practitioners left in NZ. Identifying existing cobblers and shoemakers, capturing their knowledge, and training apprentices is a priority. The trade training program (Doc #156) should include cobbling.

Key skills:

• Last-making (carving foot-shaped wooden forms)
• Pattern-making and cutting
• Hand-stitching with waxed thread
• Sole attachment (welting, pegging, nailing)
• Sole shaping and finishing
• Repair — resoling, patching, re-stitching

7.7 Economic justification for footwear workshop

A small regional cobbling workshop (2–3 trained cobblers) producing 500–1,000 pairs of shoes per year requires approximately 3–4 person-years of labour annually (including hide preparation and tanning). The alternative — going without shoes — is not viable for a population engaged in physical work. Even against extending existing footwear through repair alone, dedicated production must begin by Year 3–5 as imported footwear degrades. The labour cost is modest relative to the necessity.

8. SEWING NOTIONS AND FASTENERS

8.1 The small-items problem

Modern garments depend on dozens of small manufactured components: zippers, elastic, buttons (plastic), snaps, hooks and eyes, velcro, buckles, rivets. Most of these are imported and cannot be manufactured in NZ in the near term. The existing stock of sewing notions in NZ (in haberdashery shops, warehouses, private collections) is finite.

8.2 NZ-producible substitutes

Item	Imported version	NZ substitute	Notes
Buttons	Plastic, metal	Bone, wood, horn, shell (paua, mussel), coconut shell, metal	Bone and horn buttons were standard before plastic. NZ has abundant animal bone from meatworks. Paua shell buttons are a NZ tradition.
Zippers	Metal or plastic zip with slider	Buttons, toggles, ties, lacing, hook-and-eye	No NZ-producible zipper. Existing zippers should be salvaged from worn-out garments and reused. Garment design should shift to button or tie closures.
Elastic	Synthetic rubber/spandex	Drawstrings, buttons, knitted ribbing, tied waistbands	No NZ-producible elastic. Garment design must adapt — historically, all clothing used non-elastic closures.
Thread	Polyester or cotton	Wool thread, muka thread, linen thread	All spun locally. Wool thread is adequate for hand sewing; machine sewing with wool thread requires adjustment.
Needles	Steel (hand and machine)	Steel (hand — blacksmithing; bone for coarse work)	Steel needles are durable and NZ has steel (Doc #89). Machine needles require precision manufacturing but are a feasible machine shop product (Doc #91).
Pins	Steel	Steel (drawn wire — Doc #52)	Simple to produce from wire.
Buckles	Metal or plastic	Metal (steel, copper, brass)	Blacksmithing or casting. Simple shapes.
Snaps/poppers	Metal	Hook-and-eye, buttons	Snaps require precision stamping. Simpler closures substitute.

8.3 Zipper salvage

Zippers are the most functionally valuable fastener that NZ cannot produce. A working zipper from a worn-out garment should be carefully removed and reused. This is basic practice — a competent seamstress can remove and reinstall a zipper. NZ’s stock of millions of zippers (on existing garments) will last many years if salvaged rather than discarded.

9. STAGED DEVELOPMENT PLAN

9.1 Phase 1 (Months 0–12): No production needed — prepare

Actions:

1. Do not spend political capital on clothing. Focus government effort on actual emergencies (fuel, food, medicine, public order).
2. Include textile-relevant assets in the national asset census (Doc #8): Industrial and domestic sewing machines, knitting machines, spinning wheels, looms, tannery equipment, wool processing equipment, stocks of sewing notions (thread, needles, zippers, buttons, elastic), fabric stocks in retail and wholesale channels.
3. Identify skilled practitioners: Spinners, weavers, knitters, dyers, tailors, cobblers, tanners. Register through the skills census.
4. Engage weaving and spinning guilds: Weavers, Spinners and Woolcrafts NZ (national body and local guilds), National Maori Weavers Collective. These organisations become the knowledge base for scaled-up production.
5. Secure the wool processing chain: Ensure existing scouring plants, small-scale wool processors, and wool stores continue operating. Wool that would normally be exported stays in NZ.
6. Begin community clothing exchanges for children’s clothing and work clothing. Use existing charity shop networks.
7. Promote repair. Public messaging: mend, patch, darn. Simple instructional materials distributed through community channels.

9.2 Phase 2 (Years 1–3): Build capability

Actions:

8. Launch training programs in spinning, knitting, weaving, and basic garment construction. Use guild members and experienced crafts practitioners as instructors. Target: 5,000–10,000 new spinners/knitters in Year 1, scaling up in subsequent years.
9. Organise community knitting production for priority items: socks, underwear, hats, gloves, children’s clothing.
10. Establish regional wool processing centres — at minimum: scouring (using existing or improvised facilities), carding, and yarn production. Target: 5–10 regional centres covering all major population areas.
11. Build spinning wheels and looms using local timber. Distribute designs and carpentry instructions. Target: 1,000+ new spinning wheels in Year 1–2.
12. Identify and activate domestic knitting machines. Redistribute to production centres or skilled knitters.
13. Begin tanning operations using vegetable tanning (wattle bark, manuka bark). Target: 2–3 pilot tanneries operational by end of Year 2, producing leather for footwear.
14. Train cobbling apprentices. Identify all existing shoemakers and cobblers; begin apprenticeship programs. Target: 50–100 trained cobblers by end of Year 3.
15. Begin cobbling workshops focused initially on repair and resoling of existing footwear, transitioning to new production as leather becomes available.
16. Establish possum fur collection integrated with pest control operations. Process fur for blending with wool.

9.3 Phase 3 (Years 3–7): Scale production

Actions:

17. Scale yarn production to meet growing demand as existing clothing stocks thin. Industrial spinning frames should be under construction or operational by Year 3–5 (machine shop projects, Doc #91).
18. Begin woven fabric production from NZ wool. Initially hand-loom production; power looms designed and built through Phase 3.
19. Scale footwear production. Regional cobbling workshops producing new boots and shoes from NZ leather. Target: 50,000+ pairs per year by Year 5.
20. Develop oilskin production for waterproof outerwear using locally produced linseed oil or tallow wax on woven fabric.
21. Establish quality grading for NZ-produced wool yarn, fabric, and leather.
22. Trial linseed cultivation (Linum usitatissimum) for linseed oil (waterproofing) and potentially linen fiber (a long-term complementary textile to wool).

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

Actions:

23. Power loom production. Build and deploy power looms for wool fabric. Target: multiple mills operating by Year 10.
24. Industrial knitting machines. Build or acquire through trade. High-volume sock and underwear production.
25. Full leather tanning industry serving footwear, belts, bags, protective clothing, and other markets.
26. Explore rubber-soled footwear if natural rubber becomes available through trade with tropical regions.
27. Export potential: If NZ wool textile production exceeds domestic needs, finished garments and fabric become trade goods, particularly for Pacific partners with fewer cold-weather resources.

10. ECONOMIC JUSTIFICATION

10.1 Person-years required for a domestic clothing and footwear program

Reaching meaningful domestic textile and footwear output requires sustained labour commitments across several distinct trades. The estimates below are order-of-magnitude figures; actual requirements depend heavily on the degree of mechanisation achieved by each phase.

Textile production workforce (Year 5 target — basic needs coverage):

Role	Estimated full-time equivalents	Basis
Wool scouring and processing operators	200–400	Existing plant capacity; modest expansion
Carders, spinners (hand and machine)	5,000–15,000	At 1–3 kg yarn/worker/week, covering ~10,000 tonnes finished goods
Weavers (hand loom, transitioning to power loom)	2,000–6,000	At 1–3 m fabric/worker/day
Knitters (hand and domestic machine)	8,000–20,000	Producing socks, underwear, jumpers, hats
Garment cutters and sewers	3,000–8,000	Garment assembly from woven and knitted fabric
Dyers, finishers, waterproofers	300–600	Natural dyeing and lanolising
Trainers and guild instructors	500–1,000	Scaling craft knowledge to production workforce
Total textile workforce	~19,000–50,000 FTEs	Wide range reflects mechanisation pathway

Footwear production workforce (Year 5 target — 50,000+ pairs/year):

Role	Estimated full-time equivalents	Basis
Tanners (vegetable tanning operations)	150–300	At 3–5 hides/tanner/day through full process
Cobblers and shoemakers	200–500	At 1–3 pairs/cobbler/day (welted construction)
Last-makers and pattern-cutters	30–60	Specialist tooling role
Cobbling apprentices in training	100–300	Pipeline for Years 3–7 scale-up
Total footwear workforce	~500–1,200 FTEs	Scaling further in Phase 3–4

Combined program (Phase 2 steady state): Approximately 20,000–50,000 full-time equivalents, representing roughly 1–2% of NZ’s labour force of approximately 3.0–3.2 million.³⁶ At the high end of mechanisation, this drops to 10,000–20,000 workers. Historical pre-industrial societies allocated 5–15% of total labour to textile production; NZ’s wool abundance and the option to mechanise mean a substantially lower allocation is achievable.

This is a large programme but not an implausible one — comparable in scale to NZ’s existing healthcare or construction workforce. The key constraint is not labour availability but trained labour: spinners, weavers, cobblers, and tanners must be trained before they are productive, and training takes months to years (Section 9.2).

10.2 Local production versus rationing existing stocks to exhaustion

Two stylised strategies bracket the range of options:

Strategy A — Ration and delay: Distribute existing clothing and footwear stocks through managed rationing, defer domestic production investment, and rely on stocks until trade eventually resumes. No capital or training expenditure in Years 1–3.

Strategy B — Parallel build: Maintain redistribution and rationing of existing stocks while simultaneously building domestic production capability from Year 1. Requires training investment, machine-building effort, and organisational infrastructure.

The case for Strategy B over Strategy A rests on three observations:

1. Stocks are uneven and non-renewable. Existing footwear — particularly work boots — will wear through on an unpredictable schedule tied to individual usage rates. Once a pair of boots fails, there is no rationing mechanism that produces a new pair. Stocks cannot be stretched indefinitely; they deplete continuously regardless of management.

2. Production capability has a long lead time. A trained cobbler who begins apprenticeship in Year 2 is productive in Year 4. A tannery begun in Year 2 produces usable leather in Year 3–4 (vegetable tanning takes months). A spinning and weaving workforce trained in Year 1 is productive in Year 2. If investment is deferred to Year 4 (when shortages become acute), the production response does not arrive until Year 6–8 — by which time the workforce engaged in physical labour is operating in failed footwear and worn-out work clothing.

3. The cost of investment is low relative to necessity. Training a person to knit competently takes weeks. Building spinning wheels costs timber and woodworking time. Establishing a tannery uses hides that are a by-product of food processing and bark that is otherwise a forestry waste product. These are low-cost investments relative to the alternative.

Breakeven timeline: Under Strategy B, domestic production begins supplementing existing stocks in Years 2–3 (knitted items: socks, hats, underwear) and reaches meaningful volume in Years 3–5. The cumulative labour investment in Years 1–3 (primarily training, equipment-building, and pilot production) pays off when existing stocks would otherwise be failing in Years 4–6. On any reasonable estimate of the social cost of a recovery workforce operating without adequate footwear and clothing, breakeven is reached well within the planning horizon.

Under Strategy A, NZ would arrive at Year 5–7 with depleted stocks and no production capability — and would then face the same training and equipment investment at a moment of genuine shortage, with a workforce whose productivity and health have already been compromised. There is no plausible scenario in which deferral is cheaper.

10.3 Opportunity cost: competition for shared resources

The clothing and footwear programme competes with other recovery priorities for three resources in particular.

Harakeke fiber is subject to direct competition. Harakeke has roles across multiple recovery domains: rope and cordage (Doc #100), canvas and sacking (Doc #100), Maori cultural practice, and clothing (outer garments, work aprons). All of these are legitimate recovery uses, and harakeke cultivation takes years to establish at scale. The clothing programme should not plan on large volumes of harakeke fiber: its primary role is supplementary outer garments and sacking. Wool is the primary textile; harakeke is secondary. Priority allocation to cultural weavers (kairaranga) should be protected — the garments they produce serve identity and morale functions that have recovery value beyond their physical utility.

Leather and hides face competition between footwear production and other leather goods: belts, bags, harnesses, machinery components, upholstery. The volume of hides from NZ’s pastoral farming is large (millions of cattle and sheep processed annually), and the constraint is tanning capacity rather than raw hide volume. Even so, planning should explicitly allocate hide volumes by end use — structural footwear leather (thick, firm, vegetable-tanned) is a different product from the softer leather needed for garments or equipment, and different hide grades and tanning routes serve different purposes. A hide that becomes a work boot sole is not available for a horse harness.

Skilled workers are the tightest competition. Craftspeople capable of training textile or footwear apprentices — experienced spinners, weavers, cobblers, tanners — are few in number and are simultaneously in demand for direct production, teaching, equipment design, and quality oversight. The machine shop workforce (Doc #91) needed to build spinning frames, power looms, and knitting machines overlaps significantly with the workforce required for other mechanisation projects (tools, generators, agricultural equipment). Explicit prioritisation is required: the machine shop cannot build everything simultaneously, and textile equipment competes directly with agricultural machinery, medical equipment, and other Phase 2–3 fabrication demands.

A conservative planning assumption is that machine shop capacity is the binding constraint on mechanised textile production, and that the hand-production pathway (trained spinners and knitters using wheels and needles, not frames and machines) should be sized to carry most of the load in Years 1–5, with mechanised production supplementing rather than replacing it until machine shop capacity frees up.

11. CRITICAL UNCERTAINTIES

Uncertainty	Impact	Mitigation
Existing clothing stock longevity — how long do wardrobes actually last under recovery conditions?	Determines when domestic production must be online	Monitor through community-level needs assessment. Promote repair and redistribution to extend stocks.
Wool production under nuclear winter — how much does the flock shrink?	Determines raw material availability. Even at 50% of normal, wool supply is ample for clothing.	Track flock numbers annually. Prioritise wool allocation if supply tightens.
Speed of training new spinners, weavers, and cobblers	Determines when scaled production is possible	Begin training in Year 1. Use experienced craft practitioners as instructors.
Machine shop capacity for textile equipment	Spinning frames, power looms, and knitting machines compete with other demands on Doc #91 capacity	Prioritise within the national manufacturing plan.
Chrome tanning chemical depletion	Limits production of soft leather for shoe uppers	Transition to vegetable tanning. Accept stiffer leather.
Rubber sole substitute viability	Leather soles are worse — how much worse in practice?	Experimental program on recycled rubber soles (linked to Doc #33). Hobnailed leather as interim.
Elastic and zipper stock depletion	Affects garment design and comfort	Shift garment design to non-elastic, non-zipper closures. Salvage from worn-out garments.
Number of operational domestic knitting machines in NZ	Could significantly accelerate garment production if identified and deployed	Census (Doc #8).
Linseed cultivation viability under nuclear winter	Affects waterproofing capability and potential linen production	Trial plots in Phase 2. May not be viable until Phase 3 when conditions warm.

13. SUMMARY

Clothing and footwear are not an immediate emergency, and treating them as one would waste government attention needed elsewhere. NZ has years of existing stock and should use that time to rebuild domestic production capability.

NZ’s pathway to clothing self-sufficiency runs through wool. The country produces more wool than it needs for domestic clothing — the constraint is not raw material but mid-chain processing capacity (spinning, weaving, knitting) and the skills to perform it. Both can be developed within 3–7 years through a combination of training (using NZ’s existing craft community as instructors), hand production (knitting and hand weaving), and gradual mechanisation (building spinning frames and power looms in NZ machine shops).

Footwear is the harder problem because of the sole material constraint — the same rubber dependency that makes tires NZ’s hardest physical constraint (Doc #33) applies to shoe soles. Leather soles with hobnails are functional but wear faster than rubber. Recycled rubber from tire processing may provide some sole material. Trade-sourced natural rubber would help significantly if maritime connections develop. In the interim, extending existing footwear through repair and resoling is the priority.

The dependency chains for both clothing and footwear are traceable and domestic. Wool comes from NZ sheep. Leather comes from NZ cattle and sheep hides. Harakeke is native. Processing equipment can be built in NZ machine shops from NZ steel. The knowledge exists — in craft guilds, in Maori weaving communities, in the memories of an older generation, and in documented historical practice. What NZ needs is time, labour, and organisation to rebuild an industry it once had.

4. Footwear ownership: Industry surveys suggest 5–15 pairs per person in developed countries. The wide range reflects differences between demographics. NZ-specific data is limited.↩︎

5. NZ wool production: 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. The national sheep flock was approximately 25–26 million as of 2023, down from a peak of over 70 million in 1982. Also: Ministry for Primary Industries, Situation and Outlook for Primary Industries reports. https://www.mpi.govt.nz/↩︎

6. NZ wool types and micron ranges: NZ Merino Company, industry classifications. Fine merino (<20 microns) comes primarily from South Island high-country stations. Crossbred wool (24–35+ microns) dominates production from Romney, Perendale, Coopworth, and other breeds. See also: Beef + Lamb NZ Wool Report. https://beeflambnz.com/↩︎

7. NZ livestock processing: Stats NZ, Ministry for Primary Industries. NZ processed approximately 5–6 million cattle and 25–30 million sheep per year under normal conditions, producing significant volumes of hides and skins as by-products. Exact figures vary by year.↩︎

8. NZ tanning industry: NZ’s tanning industry has contracted significantly over recent decades. Some commercial tanning operations continue (e.g., for sheepskin products) but the industry is a fraction of its historical size. Specific current capacity figures are not readily available from public sources and should be established through the skills census (Doc #8).↩︎

9. Maori textile traditions: Pendergrast, M., “Te Aho Tapu: The Sacred Thread,” Reed Books, Auckland, 1987. Also: Mead, S.M., “Te Whatu Taniko: Taniko Weaving — Technique and Tradition,” Reed Books, Auckland, 1999. Also: Puketapu-Hetet, E., “Maori Weaving,” Pitman, Auckland, 1989. Living knowledge held by kairaranga (weavers) through the National Maori Weavers Collective and iwi-based weaving communities.↩︎

10. NZ possum population: Department of Conservation (DOC) estimates approximately 30 million brushtail possums in NZ. https://www.doc.govt.nz/ — Possums are one of NZ’s most significant invasive pests, causing extensive damage to native forests and acting as vectors for bovine tuberculosis.↩︎

11. Possum fiber yield: Estimates vary. A possum pelt yields approximately 100–200 grams of usable fiber depending on the animal’s size and season. Companies like Untouched World and Merinomink have developed possum-merino blends as premium textile products, demonstrating the fiber’s quality. See: McRae, K.C., “Possum Fibre,” in NZ Journal of Agricultural Research, various years.↩︎

12. Cotton climate requirements: Cotton (Gossypium spp.) requires a long growing season with sustained temperatures above 20 degrees C for 5–6 months, and relatively low humidity during the boll-opening period. NZ’s temperate maritime climate does not meet these requirements even under normal conditions. Under nuclear winter conditions, cotton cultivation is even less viable. See any standard agronomy reference for cotton growing requirements.↩︎

13. Maori textile traditions: Pendergrast, M., “Te Aho Tapu: The Sacred Thread,” Reed Books, Auckland, 1987. Also: Mead, S.M., “Te Whatu Taniko: Taniko Weaving — Technique and Tradition,” Reed Books, Auckland, 1999. Also: Puketapu-Hetet, E., “Maori Weaving,” Pitman, Auckland, 1989. Living knowledge held by kairaranga (weavers) through the National Maori Weavers Collective and iwi-based weaving communities.↩︎

14. Sheep welfare and shearing: Sheep bred for wool production must be shorn at least annually. Failure to shear causes wool to become matted and contaminated, leading to flystrike, heat stress, and restricted movement. Shearing is a welfare requirement regardless of wool market conditions. NZ’s shearing workforce is large and skilled — NZ shearers are among the world’s fastest. See: Beef + Lamb NZ, shearing industry data.↩︎

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

16. Drop spindle production rates: Estimates based on hand-spinning community experience. A drop spindle is inherently slower than a spinning wheel because the spinner must stop drafting to wind on completed yarn. Rates vary widely with spinner experience, fiber preparation, and target yarn weight. Fine yarn (for next-to-skin garments) is at the low end; thick, loosely spun yarn for outerwear is at the high end. See: Kroll, C., “The Whole Craft of Spinning,” Dover Publications, 1981. Also: Franquemont, A., “Respect the Spindle,” Interweave Press, 2009.↩︎

17. Spinning wheel production rates: Based on hand-spinning community benchmarks and published guides. Rates depend heavily on wheel type (single-drive vs. double-drive), fibre preparation, and target yarn weight. An experienced production spinner working consistently may approach the upper end; a competent hobby spinner working at a sustainable pace will be nearer the lower end. See: Ross, M., “The Essentials of Yarn Design for Handspinners,” Interweave Press, 1983.↩︎

18. NZ hand-spinning community: NZ has an active hand-spinning community. Weavers, Spinners and Woolcrafts NZ (the national body) represents local guilds in most centres. Spinning wheel ownership in NZ is not quantified but is significant — spinning is a popular craft hobby, and NZ spinning wheels (particularly Ashford wheels, manufactured in Ashburton) are world-renowned. Ashford Handicrafts Ltd produces spinning wheels, looms, and other textile equipment in NZ. https://www.ashford.co.nz/ — This factory is a critical national asset under recovery conditions.↩︎

19. Hand-knitting time for a jumper: Varies substantially with jumper size, yarn weight, pattern complexity, and knitter speed. A simple stockinette adult jumper in bulky yarn may take 30 hours; a complex cabled or Fair Isle jumper in finer yarn can exceed 80 hours. See: Zimmermann, E., “Knitting Without Tears,” Scribner, 1971.↩︎

20. Domestic knitting machine output: A domestic knitting machine (e.g., Brother, Silver Reed) can produce fabric at approximately 5–10 times the speed of hand knitting, depending on the pattern complexity. Simple stockinette fabric on a machine takes minutes per garment piece; hand knitting the same piece takes hours. See: knitting machine manufacturers’ specifications.↩︎

21. Hand-knitting production rates: Estimates based on typical knitting speeds of 20–40 stitches per minute for an experienced knitter, and average garment requirements (a heavy adult jumper requires approximately 100,000–150,000 stitches). Rates vary substantially with pattern complexity, yarn weight, and knitter speed. See: Zimmermann, E., “Knitting Without Tears,” Scribner, 1971 — discusses production-oriented knitting approaches.↩︎

22. Hand-spinner weekly output: This assumes approximately 20–30 hours of spinning per week (realistic for a dedicated production spinner). Output depends on yarn weight and consistency requirements — fine merino yarn for next-to-skin garments is slower to spin than coarse wool for outerwear. See footnote 27 sources.↩︎

23. Hand-weaving production rates: Based on published weaving benchmarks for production weavers on 4-shaft floor looms. Simple tabby weave in coarse yarn is faster; complex twill patterns in fine yarn are slower. Width matters significantly — a 120 cm wide loom produces twice the fabric area per metre length as a 60 cm loom but is harder to operate. See: Chandler, D., “Learning to Weave,” Interweave Press, 2009.↩︎

24. Per-person wool clothing requirements: This is an order-of-magnitude estimate. A heavy wool jumper weighs approximately 400–800 grams; a pair of wool socks 80–150 grams; wool trousers 500–1,000 grams. A minimal annual replacement set (2 pairs socks, 1 underlayer, 1 outer garment) might weigh 1.5–3 kg; full wardrobe provision from scratch approaches 5–8 kg. The wide range reflects uncertainty about how long existing clothing stocks supplement domestic production.↩︎

25. Pre-industrial textile labour: In pre-industrial societies, textile production consumed a large fraction of total labour — estimates range from 5–15% of the population engaged in spinning, weaving, and related activities. This was one of the most labour-intensive activities before mechanisation. The spinning jenny (1764) and power loom (1785) transformed this. See: Mokyr, J., “The Lever of Riches: Technological Creativity and Economic Progress,” Oxford University Press, 1990. Also: Barber, E.W., “Women’s Work: The First 20,000 Years,” W.W. Norton, 1994.↩︎

26. NZ working-age population: Stats NZ defines the working-age population as persons aged 15 and over. As of 2024, this was approximately 4.1 million. Persons actively engaged in employment or available for work (the labour force) numbered approximately 3.0–3.2 million. Under recovery conditions, effective labour force participation will change; the percentage should be recalculated against actual population in work. https://www.stats.govt.nz/↩︎

27. Wartime knitting: During both World Wars, organised voluntary knitting produced millions of garments for military personnel. NZ participated extensively — organisations like the NZ Red Cross coordinated large-scale knitting campaigns. The model of community knitting circles producing to a pattern book with centralised distribution is well-documented. See: Clarke, A., “Wartime Women: Sex Roles, Family Relations, and the Status of Women During World War II,” 1998.↩︎

28. Weavers, Spinners and Woolcrafts NZ: The national body for hand-weaving, spinning, and related textile crafts in NZ. Local guilds operate in most centres, holding equipment, running courses, and maintaining skills. https://woolcrafts.org.nz/↩︎

29. Loom construction time: Estimate based on published loom-building plans and woodworking community experience. The critical components are the frame (which must be rigid and square), the reed (which requires fine wire or thin bamboo slats at precise spacing — this is the hardest component to make from scratch), and the heddles (wire or cord loops). A loom built with a purchased reed is significantly faster than one where the reed must be fabricated. See: Leclerc looms construction guides; also Ashford Handicrafts technical documentation. https://www.ashford.co.nz/↩︎

30. 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 in Wanganui, Timaru, and elsewhere. The industry declined due to competition from cheap imports. See: McLintock, A.H. (ed.), “An Encyclopaedia of New Zealand,” Government Printer, Wellington, 1966, entries on woollen manufacturing. Also: Belich, J., “Paradise Reforged: A History of the New Zealanders from the 1880s to the Year 2000,” Allen Lane, 2001.↩︎

31. Vegetable tanning agents in NZ: Black wattle (Acacia mearnsii) is one of the world’s primary commercial tannin sources — bark tannin content approximately 35–45%. Widely planted in NZ. Manuka bark contains tannin at lower concentration. Radiata pine bark contains condensed tannins. See: Pizzi, A., “Tannin-based Adhesives,” in “Advanced Wood Adhesives Technology,” Marcel Dekker, 1994. Also: Roux, D.G. and Paulus, E., “Condensed Tannins,” in Harborne, J.B. (ed.), “The Flavonoids,” Chapman and Hall, 1975.↩︎

32. NZ chromium: NZ has no known significant chromium deposits. Chrome tanning chemicals (chromium sulfate) are entirely imported. See: GNS Science / NZ Geological Survey mineral resource assessments.↩︎

33. Welted shoe construction: Welted (Goodyear welted) shoe construction is the traditional method for quality footwear, developed in the 19th century but based on much older hand-welting techniques. A skilled cobbler using hand tools can produce 1–3 pairs of welted shoes per day. See: Thornton, J.H., “Textbook of Footwear Manufacture,” Butterworth-Heinemann, various editions. Also: Leno, J.B., “The Art of Boot and Shoemaking,” 1885 (reprinted).↩︎

34. Leather sole durability: Comparison based on traditional cobbling experience and historical accounts. Leather sole wear rates depend heavily on the walking surface (soft ground wears leather slowly; concrete and asphalt wear it rapidly), the thickness and quality of the sole leather, and the wearer’s weight and gait. Hobnails extend leather sole life by 2–4 times on hard surfaces. Rubber sole longevity similarly varies. These are approximate ranges. See: Thornton, J.H., “Textbook of Footwear Manufacture,” Butterworth-Heinemann, various editions.↩︎

35. Hobnails: Steel hobnails (studs driven into leather soles) were standard equipment for military and work boots through the early 20th century. They significantly extend leather sole life by taking the abrasion on the steel rather than the leather, and improve grip on soft ground. They damage indoor floors and are slippery on wet stone or concrete. See: any military equipment reference covering pre-WWII infantry boots.↩︎

36. NZ working-age population: Stats NZ defines the working-age population as persons aged 15 and over. As of 2024, this was approximately 4.1 million. Persons actively engaged in employment or available for work (the labour force) numbered approximately 3.0–3.2 million. Under recovery conditions, effective labour force participation will change; the percentage should be recalculated against actual population in work. https://www.stats.govt.nz/↩︎
