EXECUTIVE SUMMARY
The New Zealand dollar ceases to function as an international currency the moment global financial infrastructure collapses. Foreign exchange markets, cross-border payment networks, and international banking relationships all depend on systems that no longer exist. NZD holdings outside New Zealand become worthless. Foreign currency holdings within New Zealand become worthless. This international irrelevance is, paradoxically, the easy part — it does not matter because there is nothing to buy internationally through monetary exchange.
The harder question is domestic. The NZ dollar can continue to function as a medium of domestic exchange, but only if the government maintains confidence in it. Doc #148 addresses monetary policy in detail; this document focuses specifically on the medium-of-exchange problem: what people actually use to transact, how the government manages the transition from a modern monetary economy to a recovery economy, and how trade with Australia and other partners operates when no currency is internationally accepted.
The central argument is practical: NZ should maintain the NZ dollar as the domestic currency, supported by price controls on rationed goods and monetary discipline from the Reserve Bank of New Zealand (RBNZ). The alternative — allowing the dollar to collapse and reverting to barter or commodity money — imposes enormous transaction costs on the domestic economy. The NZ dollar’s value is not intrinsic; it is a social convention backed by government action. Maintaining that convention is worth significant effort because a functioning medium of exchange reduces friction in every economic transaction, from buying vegetables at a community market to paying wages for essential work.
For international trade, no fiat currency will function. Initial trans-Tasman and Pacific trade operates through barter — physical goods for physical goods, negotiated per voyage. As trade regularises, a commodity-referenced unit of account (likely anchored to one or more widely-traded physical goods such as copper or wheat) may emerge to simplify accounting. The development of a formal regional currency is a Phase 4–5 possibility, not an immediate concern.
NZ has relevant domestic precedent. The country operated an extensive system of economic controls, rationing, and managed currency from 1939 to approximately 1950.1 The UK’s parallel experience provides additional lessons.2 These precedents demonstrate that a functioning monetary system can coexist with rationing, price controls, and extraordinary government economic management — provided the government exercises monetary discipline and maintains perceived fairness.

RECOMMENDED ACTIONS
First 48 hours
Prime Minister declares the NZ dollar remains legal tender for all domestic transactions. Public statement: all wages, rents, prices, and transactions continue in NZ dollars. The government will maintain the currency’s value. This is a confidence measure — its purpose is to prevent the loss of monetary confidence that occurs if people believe money is worthless, which causes hoarding, barter reversion, and breakdown of the wage-price system (Doc #2, Doc #122).
RBNZ announces a money supply freeze. No new money creation without explicit parliamentary authorisation. The announcement must be public, clear, and repeated. The hyperinflation threat is real — if people believe the government will print money to fund spending, they will stop accepting NZ dollars in anticipation of their decline.3
Announce price controls on essential goods at pre-event levels (Doc #148, Recommended Actions). This anchors the price level and prevents rapid price escalation driven by uncertainty, which erodes confidence in money’s purchasing power.
First two weeks
Issue guidance to banks: all deposits honoured, all interest suspended, all debt repayment suspended (Doc #148, Section 5). The payment system must continue functioning — people need to be able to transfer money electronically (while systems work) and withdraw cash.
Ensure adequate physical currency circulation. RBNZ and the banking system should ensure that sufficient notes and coins are in circulation for cash transactions. As of recent years, approximately NZD 8–9 billion in notes and coins were in circulation.4 Not all of this is in active use — a significant fraction is held as store of value or is overseas. Domestic transactional demand may actually decrease as the rationed sector operates partly through allocation rather than purchase, but the market sector requires functioning cash.
Establish government ration coupon or allocation card system for rationed goods (Doc #3). This is a parallel allocation mechanism, not a replacement for money. The ration coupon entitles the holder to purchase a specified quantity at the controlled price. Money is still required for the purchase. This dual system (coupon + money) preserves the monetary system’s function while ensuring equitable distribution of scarce goods.
First month
- Announce the compensation and wage framework (Doc #3, Section 6). Every resident receives a base ration entitlement. Workers receive NZ dollar wages for their labour. The wage-price relationship is managed by the government.
Months 2–3
The 48-hour and first-week actions above are correctly urgent — financial system confidence is fragile and must be addressed immediately. The institutional buildout below, while important, can follow once the government has stabilised domestic food distribution, grid management, and basic public order.
Economic Management Authority (EMA) established (Doc #3, Section 2). The EMA coordinates monetary policy, price management, and trade exchange policy.
Establish a national price index. The EMA, working with Stats NZ, publishes a monthly price index for both rationed and market-sector goods. This provides the data needed for monetary policy decisions and — critically — provides transparency that builds public confidence. If the government claims prices are stable, people need data to verify the claim.
First three months
Develop trans-Tasman trade terms framework in coordination with Doc #148. Initial trade is barter — negotiate the first trade voyages in physical quantities (tonnes of cheese for kilograms of copper). Document agreed exchange ratios as a basis for future reference, but do not attempt to fix permanent rates.
Begin planning for medium-term trade accounting. A bilateral ledger system with Australia — tracking what each country has delivered to the other — provides the basis for trade credit. NZ may deliver food during nuclear winter (Phase 2) in exchange for mineral deliveries during industrial development (Phase 3–4). The ledger tracks the balance.
First year
Review and adjust price controls based on actual production data. Some controlled prices will be wrong — too high (encouraging waste) or too low (discouraging production). Regular adjustment based on the national price index and production data is essential.
Formalise the boundary between rationed and market sectors (Doc #3, Section 3). Goods with adequate domestic supply transition to market pricing. Goods still in acute shortage remain rationed and price-controlled.
ECONOMIC JUSTIFICATION
The cost of monetary collapse
If the NZ dollar ceases to function — if people stop accepting it in exchange for goods and services — the economy reverts to barter. Barter economies are documented throughout economic history, and their inefficiency is severe:5
- The double coincidence of wants. A carpenter who needs potatoes must find a potato grower who needs carpentry. Without money, every transaction requires this match. In a modern economy with thousands of goods and services, the matching problem is crippling.
- No unit of account. Without money, there is no common measure of value. Is one hour of carpentry worth ten kilograms of potatoes, or twenty? Every pair of goods requires its own exchange rate. With 100 goods in the economy, there are 4,950 bilateral exchange rates to negotiate — versus 100 prices denominated in a common currency.
- No store of value. Potatoes rot. Carpentry services cannot be stored. Without money, saving is difficult, which discourages production beyond immediate needs.
- Transaction costs consume productive time. Studies of barter economies estimate that the transaction cost overhead — the time spent finding trading partners, negotiating terms, and executing exchanges — consumes 10–30% of economic activity that could otherwise be productive.6
Person-years estimate: NZ’s working-age population is approximately 3.3 million. If monetary collapse forces even 10–20% of productive time into transaction overhead (finding barter partners, negotiating rates) — consistent with the 10–30% range observed in partially barterised economies7 — the cost is approximately 330,000–660,000 person-years per year, dwarfing the administrative cost of maintaining the monetary system, which Doc #3 estimates at 5,000–15,000 person-years per year for the entire economic management apparatus.8 The lower bound assumes barter emerges alongside informal credit networks that reduce matching costs; the upper bound assumes a more fragmented economy with weak social trust.
The cost of maintaining the monetary system
Maintaining the NZ dollar requires:
- RBNZ operational continuity — a small institution (approximately 400–500 staff pre-event) that continues to function. Under the baseline scenario (grid, telecommunications, and government institutions intact), the RBNZ’s core functions — monetary policy decisions, currency management, bank oversight — require no imported inputs or novel capability, though retaining key staff and maintaining institutional knowledge during workforce reallocation (Doc #145) requires deliberate management.
- Banking system operation — banks continue as payment processors and record-keepers (Doc #148, Section 5). Staff requirements likely decline as the banking system’s role narrows to payment processing and record-keeping, though the scale of reduction depends on the pace of transition from electronic to cash-based transactions.9
- Price control and rationing administration — estimated at 5,000–15,000 person-years per year across all economic management functions (Doc #3).10
- Cash distribution and management — maintaining physical currency in circulation. Existing RBNZ and bank infrastructure handles this.
Total cost: Approximately 5,000–15,000 person-years per year for the complete economic management system, of which the currency-specific component is a small fraction.
Comparison: 5,000–15,000 person-years to maintain a functioning monetary system versus 330,000–660,000 person-years in transaction costs under barter. The benefit-to-cost ratio is approximately 22:1 to 130:1, depending on assumptions about barter inefficiency and administrative overhead. Even the most conservative estimate makes this one of the clearest economic cases in the entire Recovery Library.
1. THE NZ DOLLAR: WHAT IT IS AND WHY IT WORKS
1.1 Fiat currency basics
The NZ dollar is a fiat currency — its value derives not from any physical commodity (gold, silver) but from government decree and public acceptance. As of recent years, the monetary base (notes, coins, and settlement balances at RBNZ) was approximately NZD 40–50 billion, while broader money supply measures (including bank deposits) were approximately NZD 350–400 billion.11 Most “money” in the NZ economy is not physical cash — it is electronic balances in bank accounts, created through the banking system’s lending activities.
Under recovery conditions, the distinction between physical cash and electronic money matters:
- Physical cash (notes and coins) continues to function as long as people accept it. Physical cash does not require electricity, telecommunications, or functioning banks. It is the most robust form of money.
- Electronic money (bank deposits, EFTPOS transactions) continues to function as long as the banking system and telecommunications infrastructure operate. NZ had one of the highest per-capita EFTPOS usage rates in the world pre-event, with approximately 120,000–150,000 terminals processing the majority of retail transactions.12 Under the baseline scenario (grid and telecom functional), electronic money continues for years. As infrastructure degrades — particularly EFTPOS terminal hardware, which has a typical operational life of 5–8 years without replacement parts — the economy shifts increasingly toward cash transactions.
- The transition from electronic to cash should be planned, not left to happen chaotically. RBNZ should ensure that sufficient physical cash is in circulation to handle the transaction volume if electronic systems degrade. This may require printing additional notes — which is money creation and must be managed carefully to avoid inflationary effects. Note printing depends on NZ’s banknote production capability: NZ banknotes were printed by the Canadian Bank Note Company (CBNC) pre-event, not domestically.13 Domestic note production would require repurposing high-security printing facilities, sourcing or substituting polymer substrate (NZ banknotes are polymer, not paper), and producing security inks — a capability that would take months to establish even under favourable conditions. In the interim, RBNZ should redistribute existing cash holdings from bank vaults and maximise the useful life of notes already in circulation.
1.2 Why the NZ dollar can survive
The NZ dollar can maintain domestic value because:
- The government denominates all its activities in NZD. Wages for essential workers are paid in NZD. Ration prices are set in NZD. Taxes (when they resume in any form) are collected in NZD. As long as the government transacts in NZD, people have reason to hold and accept NZD.
- The government controls the money supply. Through the RBNZ, the government can limit money creation, preventing the hyperinflationary spiral that destroys currencies.14
- Price controls anchor the value. If a litre of milk costs NZD 3 and a kilogram of cheese costs NZD 15, and these prices are enforced, then NZD has a defined purchasing power. The ration coupon + price control system gives money a real, tangible value — you know what you can buy with it.
- NZ has institutional credibility. Pre-event NZ had strong institutional trust — the RBNZ was internationally respected for its inflation-targeting regime, the government had a reputation for fiscal responsibility, and there was no recent history of monetary mismanagement.15 This trust is an asset that persists into the crisis, though it can be squandered.
1.3 How the NZ dollar can fail
The NZ dollar fails if people stop believing it will retain value. The mechanisms of failure are well-documented:16
- Uncontrolled money creation. If the government prints money to fund emergency spending — paying workers by creating new NZD, buying supplies by creating new NZD — without a corresponding increase in goods available for purchase, prices rise. If money creation is unchecked, hyperinflation results and the currency becomes worthless.
- Loss of government authority. If the government itself loses legitimacy — through corruption, incompetence, or perceived unfairness — people lose confidence in its ability to manage the currency.
- Parallel currencies emerge. If people begin transacting in cigarettes, ammunition, or foreign currency rather than NZD, the NZ dollar’s function erodes. This typically happens when money fails to serve its purpose — when prices are unstable, when goods cannot be purchased at listed prices, or when confidence in the government is low.
- Black market pricing diverges from official pricing. If official prices are NZD 3 per litre of milk but the actual market-clearing price on the black market is NZD 30, the official price is fiction. The wider the gap between official and actual prices, the less meaningful the official currency becomes.
2. THE RATION COUPON SYSTEM
2.1 How ration coupons interact with money
A ration coupon is not money. It is an entitlement to purchase a specific quantity of a rationed good at the controlled price. The transaction requires both the coupon and the money. This dual requirement serves several purposes:
- Equitable distribution. The coupon ensures everyone gets their fair share. Money alone would allow the wealthy to buy more than their share; coupons prevent this.
- Preserves the monetary system. If rationed goods were distributed free (coupon only, no money required), money would lose a major part of its function. By requiring payment at a nominal price, the system keeps money circulating and meaningful.
- Prevents waste. A positive price, even a low one, discourages waste more effectively than free distribution.
- Enables the market sector. Money received for rationed goods enters the government’s revenue stream, which can be used to pay wages — completing the monetary circuit.
2.2 Ration coupon design
NZ’s WWII ration coupons provide a direct precedent.17 Practical design requirements:
- Printed, serialised, and difficult to counterfeit. Use the national printing capability (Doc #5, Doc #29) to produce coupons with serial numbers, security features (watermarks, coloured paper, micro-printing where capability exists), and clear denomination. The dependency chain for coupon production requires: paper stock (NZ has domestic paper manufacturing at Oji Fibre Solutions, Penrose, though specialty security paper may require pre-positioned imported stock or substitution with locally produced watermarked paper); printing ink (limited domestic production — existing stocks deplete over 1–3 years depending on print volume; see Doc #5); functional offset or letterpress printing equipment; and trained print operators. Security features beyond basic serial numbering and coloured paper stock may not be feasible once imported consumables (specialty inks, holographic foils) are exhausted.18
- Time-limited. Coupons expire after a defined period (monthly or quarterly). This prevents hoarding and simplifies administration.
- Category-specific. Separate coupon types for food, fuel, pharmaceuticals, and other rationed categories. This prevents trading across categories (using fuel coupons to buy food) unless the government deliberately permits it.
- Non-transferable in theory, semi-transferable in practice. NZ’s WWII experience and the UK’s experience both showed that some informal coupon trading occurred and was largely tolerated. Attempting to suppress all coupon trading wastes enforcement resources and creates resentment. The practical approach: formally prohibit sale of coupons (to prevent organised coupon markets that would undermine equitable distribution) but tolerate neighbour-to-neighbour swaps.19
2.3 Digital versus physical coupons
Under the baseline scenario (telecommunications and banking systems functional), an electronic ration card system is feasible and reduces administrative overhead — each resident has a card linked to their allocation, scanned at the point of purchase, similar to NZ’s existing Community Services Card or SuperGold Card systems.20 An electronic system eliminates the printing, distribution, and collection costs of physical coupons and enables real-time tracking of allocation usage. However, physical coupons have advantages that electronic systems cannot match: they function without electricity or telecommunications, they are understandable without technical literacy, and they cannot be disabled by system failures. The performance gap is significant — physical coupons require approximately 3–10 times the administrative person-hours for distribution, collection, and reconciliation compared to electronic systems, based on UK WWII rationing administration costs scaled to modern population.21 The system must have a physical fallback (printed coupons) for when electronic systems degrade. The fallback should be designed and tested before it is needed, not improvised under pressure.
3. COMMODITY MONEY: THE TEMPTATION AND THE PROBLEMS
3.1 Why commodity money seems appealing
If confidence in the NZ dollar wavers, commodity money — using a physical good (gold, silver, copper, tobacco, ammunition) as currency — can seem like a reliable alternative. The appeal is that a physical commodity has intrinsic value: gold is gold regardless of what the government does.
Historical precedent supports commodity money’s viability. Precious metals served as money for millennia. Tobacco was currency in colonial Virginia. Cigarettes were currency in post-WWII German prisoner-of-war camps. Salt was currency in parts of Africa (the word “salary” derives from the Latin salarium, related to salt).22
3.2 Why commodity money is worse than managed fiat for NZ
Despite the appeal, commodity money is significantly worse than a well-managed fiat currency for NZ’s recovery:
- NZ has limited precious metals. NZ’s gold reserves are small — the RBNZ held minimal gold reserves pre-event, and NZ’s alluvial gold deposits (West Coast, Coromandel) are modest.23 Silver deposits are similarly limited. There is not enough precious metal in NZ to serve as a monetary base for a functioning economy.
- Commodity money constrains the money supply. If money is gold and NZ has X kilograms of gold, the money supply is fixed at X kilograms. This is a problem because the money supply needs to expand as the economy grows — more transactions require more money. Under a gold standard, economic growth is constrained by the availability of gold, which has nothing to do with the economy’s productive capacity. This constraint is why virtually every country abandoned the gold standard during the 20th century.24
- Commodity money diverts productive resources. If copper is money, then copper used as money cannot be used to make wire, which cannot be used to maintain the electrical grid, which is NZ’s most critical infrastructure asset. Using a useful commodity as money imposes an opportunity cost that NZ cannot afford.
- Commodity money does not prevent the problems it is supposed to solve. Commodity currencies can still be debased (the Roman Empire debased its silver coinage over centuries), and commodity money does not prevent black markets, price instability, or economic mismanagement. It constrains the government’s ability to respond flexibly to changing conditions — which under recovery conditions is a liability, not an asset.
3.3 When commodity money makes sense
Commodity money may emerge naturally in specific contexts:
- International trade. Between NZ and Australia, where no fiat currency is accepted by both sides, physical commodities are the natural medium of exchange. A kilogram of copper has value in both countries regardless of either government’s monetary policy. This is barter formalised into standard units, and it functions adequately for trade between sovereign entities with low transaction frequency.
- If fiat money fails. If the NZ dollar collapses despite government efforts — through hyperinflation, institutional failure, or loss of public confidence — commodity money will emerge as a fallback. The government’s task is to prevent this by maintaining the NZ dollar, not to plan for commodity money as the primary system.
- Local and informal exchange. In very small communities, direct barter or commodity exchange may be more practical than cash transactions, regardless of the formal monetary system. This is harmless and should be tolerated.
4. BARTER SYSTEMS: ROLE AND LIMITATIONS
4.1 Barter in the domestic economy
Pure barter — I give you potatoes, you cut my hair — will emerge in the recovery economy regardless of what the government does. In small communities, among neighbours, and for irregular transactions, barter is natural and efficient. The government should not attempt to suppress it.
However, barter cannot serve as the primary allocation mechanism for a complex economy. The limitations are fundamental:25
- Double coincidence of wants (discussed above)
- Indivisibility. A cow cannot be divided to buy a haircut. Money is infinitely divisible; physical goods are not.
- No deferred payment. Barter requires simultaneous exchange. Credit — promising to deliver goods later — requires trust and enforcement mechanisms that money and contracts provide.
- No standard of value. Without a common unit of account, comparing the value of different goods requires constant bilateral negotiation.
4.2 Organised barter networks
Some communities may establish organised barter systems — lists of available goods and services, community notice boards, matching services. These can be useful supplements to the monetary economy, particularly in the early months when market-sector activity is developing. The government should encourage these systems as complements to the NZ dollar, not as replacements for it.
LETS (Local Exchange Trading Systems): NZ had an active LETS community pre-event, where members tracked exchanges using a community-created unit of account (often called “greens” or similar).26 LETS effectively creates a local complementary currency backed by mutual obligation rather than government decree. These systems can function alongside the NZ dollar, serving communities where cash is scarce or where community cohesion makes mutual trust viable. The government should not suppress LETS but should not rely on them either — they work at the scale of dozens to hundreds of participants, not at national scale.
Koha-type reciprocal exchange: Māori communities and other high-trust small communities operate a form of social credit — gift-giving with an expectation (but not explicit demand) of reciprocal exchange over time.27 This functions as a credit system without formal contracts, courts, or currency. Under recovery conditions where formal credit infrastructure is impaired, koha-type reciprocity operates naturally in communities with strong social bonds. Marae-based communities already operate partial gift economies that will scale under recovery conditions. The EMA should ensure that the formal rationing and monetary systems do not inadvertently criminalise or suppress these exchange practices where they are functioning effectively.
5. INTERNATIONAL TRADE: THE MEDIUM-OF-EXCHANGE PROBLEM
5.1 Why fiat currencies fail internationally
The NZ dollar is backed by the NZ government’s authority within NZ. Australia has no reason to accept NZD — it cannot use NZD to buy anything in Australia, and its value depends on a government Australia does not control. The same applies in reverse: NZ has no reason to accept Australian dollars. Both currencies are domestic instruments with no international purchasing power.
This is not a theoretical problem — it is the immediate practical barrier to international trade. Doc #148 discusses the trans-Tasman trade framework in detail. This section addresses the specific medium-of-exchange challenge.
5.2 Phase 1: Pure barter
Initial trans-Tasman trade operates through direct barter. A sailing vessel carries NZ cheese, preserved meat, wool, and timber to Australia; it returns with Australian copper, tin, coal, and other minerals. The terms are negotiated per voyage — how many tonnes of cheese for how many kilograms of copper.
Advantages of barter for initial trade: - No trust in either country’s currency is required - Both sides can inspect the physical goods - The transaction is complete on delivery — no deferred obligations
Disadvantages: - Every voyage requires fresh negotiation of terms - No standard for comparing the value of different goods across voyages - Timing mismatches are difficult to manage (NZ needs copper now; Australia needs food now; but the goods available for trade on a given voyage may not match)
5.3 Phase 2: Commodity-referenced accounting
As trade regularises, both countries benefit from a common unit of account — a standard measure of value that simplifies negotiation. The most practical approach is a commodity reference: both sides agree that trade will be accounted in terms of a specific physical commodity, even if that commodity is not physically exchanged on every voyage.
Candidates for the reference commodity:
| Commodity | Advantages | Disadvantages |
|---|---|---|
| Copper (per kg) | Widely needed, durable, measurable, NZ and Australia both use it | Value fluctuates with industrial demand |
| Wheat (per tonne) | Widely understood, essential, historical precedent | Perishable, bulky, value varies with harvest |
| Gold (per gram) | Traditional monetary commodity, divisible, durable | Neither country has large reserves; diverts useful metal |
| Labour-hour equivalent | Directly measures productive capacity | Hard to standardise across countries |
| Basket of commodities | Reduces volatility, more representative | Complex to calculate and agree |
Recommendation: A basket approach is most robust — define a standard “trade unit” as equal to, say, 1 kg of copper + 10 kg of wheat + 0.5 kg of wool, or some similar combination of goods that both countries produce and trade. This reduces the risk that a single commodity’s price fluctuation distorts trade terms. The specific basket composition should be negotiated bilaterally and adjusted periodically as trade patterns develop.
5.4 Phase 2–3: Trade credit and bilateral ledger
NZ’s food is most valuable to Australia during nuclear winter (Phase 2), when Australian agriculture is severely stressed. Australian minerals are most valuable to NZ during industrial development (Phase 3–4), when NZ is building manufacturing capability. This timing mismatch requires trade credit — NZ delivers food now, Australia delivers minerals later, with a bilateral ledger tracking the running balance.
Ledger design: - Both governments maintain a copy of the ledger - Each transaction (voyage) is recorded in physical quantities and in the agreed commodity-referenced unit - Net balance shows which country has delivered more value than it has received - Periodic (annual or semi-annual) settlement review adjusts terms and addresses imbalances - The ledger is a bilateral government instrument — not enforceable by courts, but maintained by mutual interest and the ongoing trade relationship
This is not a new invention. Bilateral clearing arrangements were used extensively in international trade during the 1930s–1950s, when the international monetary system was disrupted. The UK, Germany, and several other countries maintained bilateral trade ledgers during and after WWII.28
5.5 Phase 4–5: Regional currency possibility
As trade networks develop — NZ, Australia, and potentially Pacific Island nations — the transaction costs of bilateral barter and commodity-referenced accounting may justify a shared regional currency or settlement mechanism. This is a Phase 4–5 development at the earliest and involves complex questions of monetary sovereignty, governance, and institutional design that are beyond the scope of this document’s immediate recommendations.
The key principle for long-term planning: any regional currency arrangement must preserve each country’s monetary sovereignty over its domestic economy. NZ should not subordinate its domestic monetary policy to a regional institution until the institutional framework for such an arrangement is robust and the benefits clearly outweigh the costs. The European Union’s experience with the euro — which constrained member states’ ability to respond to country-specific economic shocks — is a relevant cautionary precedent, though the circumstances are very different.29
6. ESTABLISHING TRADE EXCHANGE RATES
6.1 The problem
When NZ and Australia begin to trade, they must agree on terms: how much NZ food is a fair exchange for how much Australian copper? There is no market to set these rates, no currency to denominate them, and no historical precedent for the specific goods being traded under the specific conditions.
6.2 Factors that determine exchange rates
In practice, bilateral trade exchange rates will be determined by:
- Relative scarcity. If Australia is desperately short of food and NZ has surplus, NZ food commands a high price in Australian goods. If both countries have adequate food but NZ lacks copper, copper commands a high price in NZ goods.
- Production cost. How many person-hours does it take to produce a tonne of cheese in NZ versus a kilogram of copper in Australia? This provides a rough floor for exchange rates — neither country will trade at terms that make it cheaper to produce the good domestically.
- Alternatives. If NZ can obtain copper from a third source (scrap metal recycling, small domestic deposits, trade with another country), its willingness to pay Australia’s price decreases. Similarly for Australia’s alternatives to NZ food.
- Negotiating power. The country with the more urgent need — typically the country whose people are hungrier or whose industrial development is more constrained — has less bargaining power. NZ should be aware that its food surplus gives it significant leverage during nuclear winter, and should use that leverage wisely — exploitative terms would damage the long-term relationship that NZ needs for sustained mineral access.
6.3 Practical approach
The first few trade voyages should be negotiated ad hoc, with terms documented. As data accumulates, a pattern emerges — a rough sense of what an equitable exchange looks like. This pattern can be formalised into reference exchange rates, revisited periodically (perhaps annually) as conditions change.
NZ should avoid two extremes:
- Exploiting Australia’s food vulnerability to extract disproportionate mineral deliveries. This yields short-term gain but damages a relationship NZ depends on for decades. Australia’s goodwill and willingness to trade generously is worth more than the marginal copper from one-sided terms.
- Accepting unfavourable terms out of diplomatic deference. NZ’s food surplus is genuinely valuable — perhaps the most valuable trade good in the Southern Hemisphere during nuclear winter. NZ should negotiate firmly while fairly.
7. THE TRANSITION FROM EMERGENCY RATIONING TO FUNCTIONING MARKETS
7.1 The transition path
Doc #148 (Section 10) describes the sequenced transition from central allocation to market allocation in detail. For currency and exchange specifically, the transition involves:
Phase 1–2 (Emergency): - NZ dollar maintained with price controls on rationed goods - Ration coupons for essential goods - Limited market sector for surplus production, personal services, and non-rationed goods - International trade by barter
Phase 3 (Early recovery): - Ration categories progressively reduced as domestic production recovers - Market sector expanding — more goods and services transacted at market prices in NZD - International trade moving from pure barter to commodity-referenced accounting - Banking system cautiously resuming lending for productive purposes
Phase 4 (Normalisation): - Most goods returned to market allocation at market prices - Rationing maintained only for goods with no domestic production - International trade regularised with established terms and possibly a trade settlement mechanism - Banking system approaching conventional function (lending, credit, savings)
Phase 5 (Post-emergency): - Normal market economy with structural differences from pre-event - NZ dollar functioning as a conventional fiat currency - International trade operating through established bilateral or multilateral arrangements
7.2 Trigger-based transitions
Following the approach in Doc #148, transitions should be governed by measurable triggers rather than arbitrary timelines:
| Trigger | Currency/Exchange Action |
|---|---|
| Market-sector prices for a food category stable for 6+ months | Remove price controls for that category |
| Domestic production of a good exceeds 120% of ration allocation for two quarters | That good exits rationing; ration coupons no longer required |
| General inflation below 10% annually for two consecutive years | RBNZ reviews monetary settings; consider cautious expansion of money supply to match economic growth |
| Trans-Tasman trade reaches regular scheduled service | Formalise commodity-referenced accounting; establish standing trade terms |
| Banking system operational with stable deposits | Cautiously resume lending, starting with productive loans (agricultural, manufacturing) |
8. CRITICAL UNCERTAINTIES
| Uncertainty | Impact if Wrong | Resolution Method |
|---|---|---|
| Public confidence in NZ dollar | If confidence collapses, economy reverts to barter with 330,000–660,000 person-years in annual transaction costs | Monetary discipline; transparent price data; avoid money-printing; maintain institutional credibility |
| Hyperinflation risk | If government funds spending through money creation, currency collapses | RBNZ independence; parliamentary oversight of money supply; public reporting |
| Black market scale | If black market prices diverge sharply from official prices, the rationing system loses credibility and the currency’s effective value is uncertain | Perceived fairness in rationing; proportionate enforcement; adjust official prices when they diverge too far from reality |
| Electronic payment system longevity | If banking/telecom infrastructure degrades faster than expected, cash demand spikes and may exceed physical currency supply | Pre-position sufficient physical currency; plan for note printing; manage transition to cash-primary economy |
| Australia’s willingness and capacity to trade | If Australia is unable or unwilling to trade, NZ lacks critical minerals regardless of exchange mechanism | Multiple trade relationships (Pacific, South America); domestic scrap metal recycling (Doc #90); diplomatic engagement (Doc #151) |
| Trade credit default | If bilateral ledger accumulates large imbalances that one country cannot or will not settle, the trade relationship is strained | Regular settlement reviews; balanced trade terms; cap on acceptable imbalances; maintain relationship goodwill |
| Duration of the barter phase | If formal trade accounting takes longer to develop than expected, transaction costs of ad hoc negotiation slow trade development | Accept that early trade will be inefficient; invest in establishing the commodity-referenced accounting system as a priority |
| Commodity money emergence | If communities adopt commodity currencies (tobacco, ammunition) despite government efforts, the NZD faces competition | Maintain NZD’s utility by ensuring rationed goods require NZD; demonstrate monetary stability through transparent data; do not criminalise barter or complementary currencies |

(1965), “War Economy,” Official History of New Zealand in the Second World War 1939–45, Historical Publications Branch. https://nzetc.victoria.ac.nz/tm/scholarly/tei-WH2Econ.html — NZ operated comprehensive rationing (food from 1943, petrol, clothing), price controls through the Economic Stabilisation Commission, and import licensing from 1939 through approximately 1950. The NZ pound remained the domestic currency throughout; its international convertibility was managed through exchange controls. Ration coupons were printed by the Government Printing Office and distributed through local rationing committees.↩︎
Zweiniger-Bargielowska, I. (2000), “Austerity in Britain: Rationing, Controls, and Consumption, 1939–1955,” Oxford University Press. The UK operated the most extensive democratic rationing system of WWII, maintaining a functioning monetary economy alongside comprehensive rationing for fifteen years (1940–1954). The pound sterling maintained its domestic purchasing power throughout, largely because the government exercised fiscal and monetary discipline. Black markets existed but remained marginal — the system’s perceived fairness was the main reason for compliance.↩︎
Hanke, S.H. and Krus, N. (2013), “World Hyperinflations,” in Reinhart, C.M. and Savastano, M.A. (eds.), “The Oxford Handbook of the History of Finance.” Hyperinflation has occurred dozens of times in modern history, always associated with uncontrolled government money creation. Zimbabwe (2008: 79.6 billion percent per month), Hungary (1946: 41.9 quadrillion percent per month), and Weimar Germany (1923: 29,500% per month) are the most extreme cases. The common pattern: government faces a fiscal crisis, funds spending by printing money, prices rise, government prints more money to keep up with prices, and the spiral accelerates until the currency becomes worthless. Prevention requires institutional constraints on money creation — the RBNZ’s independence and parliamentary oversight serve this function.↩︎
Reserve Bank of New Zealand, “Money and Credit Aggregates” and “Currency in Circulation” data series. https://www.rbnz.govt.nz/ — Total currency in circulation (notes and coins) was approximately NZD 8–9 billion in recent years. The broader money supply (M3, including bank deposits) was approximately NZD 350–400 billion. The vast majority of “money” in the economy is electronic — bank deposits created through lending. Under recovery conditions, the distinction between physical cash and electronic deposits becomes operationally important as infrastructure degrades.↩︎
The inefficiency of barter economies is a foundational concept in monetary economics. Jevons, W.S. (1875), “Money and the Mechanism of Exchange,” D. Appleton and Company, provides the classic formulation of the “double coincidence of wants” problem. Modern treatment: Kiyotaki, N. and Wright, R. (1989), “On Money as a Medium of Exchange,” Journal of Political Economy 97(4), 927–954. The transaction cost estimates (10–30% of economic activity) are based on studies of economies that have partially reverted to barter, including the post-Soviet Russian economy of the 1990s, where barter comprised an estimated 50–70% of inter-enterprise transactions by 1997. See: Woodruff, D. (1999), “Money Unmade: Barter and the Fate of Russian Capitalism,” Cornell University Press.↩︎

Doc #3, footnote 6. The 5,000–15,000 person-year estimate for economic management administration is based on the staffing required for rationing administration, price surveillance, and economic coordination. For comparison, the UK employed approximately 50,000 civil servants in food rationing administration alone during WWII, serving a population approximately ten times NZ’s.↩︎
NZ’s banking sector employed approximately 25,000–30,000 people pre-event (Statistics NZ, Business Demography Statistics). The bulk of this workforce was engaged in lending, investment, compliance, and customer acquisition functions that cease to be relevant under recovery conditions. The core payment-processing and record-keeping functions — branch operations, settlement, and basic account management — likely require a fraction of this workforce, though the exact reduction depends on transaction volume and the pace of the electronic-to-cash transition. No direct precedent exists for estimating this reduction; the UK’s WWII banking sector continued to operate with reduced staff but was not subject to the same degree of functional simplification.↩︎

NZ’s Community Services Card (administered by the Ministry of Social Development) and SuperGold Card systems provide precedent for government-issued cards linked to entitlements and scanned at point of sale. The Integrated Data Infrastructure (IDI) maintained by Stats NZ and the NZ Health system’s National Health Index (NHI) provide the population database infrastructure that an electronic ration card system would build on. The primary technical requirement is EFTPOS terminal compatibility — NZ had approximately 120,000–150,000 EFTPOS terminals in operation pre-event (Paymark/Worldline NZ data), providing extensive point-of-sale coverage that could be repurposed for ration card verification while telecommunications infrastructure remains functional.↩︎
NZ banknotes have been produced by the Canadian Bank Note Company (CBNC) since 1999, printed on Guardian polymer substrate manufactured in Australia. NZ does not have domestic banknote printing capability. The polymer substrate requires biaxially oriented polypropylene (BOPP) film production — a petrochemical process that NZ lacks the feedstock and equipment to replicate domestically. If new banknotes are required and CBNC supply is unavailable, options include: (a) reverting to paper-based notes using domestic paper stock with whatever security features can be applied locally, accepting significantly reduced counterfeit resistance; (b) extending the circulation life of existing polymer notes, which are more durable than paper (typical polymer note lifespan is 2.5–4 times that of paper notes, per Reserve Bank of Australia data); or (c) transitioning to coin-only physical currency for high-security applications, supplemented by lower-security paper instruments for smaller denominations.

The RBNZ was the first central bank to adopt formal inflation targeting (1990), under the Reserve Bank of New Zealand Act 1989. NZ’s inflation-targeting framework became a model for central banks worldwide. Pre-event NZ inflation was typically within the 1–3% target range. This institutional credibility is a real asset — it means the NZ public has recent experience of a central bank that maintains price stability, which supports confidence in the NZ dollar during the crisis.

NZ’s domestic paper manufacturing capability is centred on Oji Fibre Solutions (formerly Carter Holt Harvey Pulp & Paper) at its Penrose (Auckland) and Kinleith (Waikato) facilities, producing packaging and tissue products from radiata pine pulp. Specialty security paper (with embedded watermarks, security threads, and controlled fibre composition) was not produced domestically pre-event and would require either pre-positioned imported stock or development of a simplified domestic alternative. Printing ink production in NZ was limited — the major suppliers (Siegwerk, DIC, Flint Group) operated blending and distribution facilities but imported base pigments and resins. Ink stocks for high-volume printing (rationing coupons, government forms) would likely last 1–3 years depending on print volume, after which domestically produced inks from carbon black (soot-based), linseed oil, and tallow-derived vehicles would provide a lower-quality but functional substitute. See Doc #5 and Doc #29 for detailed treatment of NZ printing capability and consumable depletion timelines.↩︎

NZ gold production data from NZ Petroleum and Minerals, Ministry of Business, Innovation and Employment. https://www.nzpam.govt.nz/ — NZ’s gold production has been modest — approximately 5,000–15,000 ounces per year from mines primarily on the West Coast and in the Hauraki (Coromandel) region. Total NZ gold reserves (geological, not monetary) are significant but require active mining. The RBNZ’s gold reserves were minimal — NZ, like most modern central banks, held foreign exchange reserves rather than gold.↩︎
The global abandonment of the gold standard is well-documented. The UK left the gold standard in 1931, the US effectively left in 1933 (full abandonment in 1971), and by the 1970s no major economy maintained gold convertibility. The fundamental problem: the money supply under a gold standard is determined by gold production, not by economic needs. During the Great Depression, the gold standard forced countries to maintain tight monetary policy when expansion was needed, deepening the depression. See: Eichengreen, B. (1992), “Golden Fetters: The Gold Standard and the Great Depression, 1919–1939,” Oxford University Press.↩︎

LETS (Local Exchange Trading Systems) were active in several NZ communities pre-event, including in Christchurch, Wellington, and various smaller towns. LETS use an internally-created unit of account to track exchanges among members. The system requires no physical currency — balances are recorded in a central ledger. LETS typically function well at small scale (50–500 members) where mutual trust and social accountability maintain compliance. At larger scale, free-riding and trust problems limit effectiveness.

Koha and utu as economic principles: Mead, H.M. (2003), “Tikanga Māori: Living by Māori Values,” Huia Publishers, pp. 28–35, 55–64 — comprehensive treatment of koha (gift exchange and reciprocity), utu (balance and reciprocal obligation), and their role in structuring Māori social and economic relationships. Also: Metge, J. (1976), “The Maoris of New Zealand: Rautahi,” revised edition, Routledge and Kegan Paul, Chapter 5 (“Economic relations”). The critical distinction between koha-based exchange and barter is the temporal dimension: barter requires simultaneous exchange of equivalent value, while koha creates an open-ended obligation to reciprocate at a socially appropriate time and level. This makes koha a form of social credit rather than a form of commodity exchange. Taonga as a concept of value: Waitangi Tribunal (2011), “Ko Aotearoa Tēnei” (Wai 262), Chapter 2, discusses how taonga encompasses both tangible possessions and intangible assets including relationships, knowledge, and language. The monetary-equivalent concept — that value is a single scalar quantity expressible in price — is a Western analytical framework that does not map cleanly onto Māori economic frameworks. Neither framework is universally correct; the practical point is that recovery conditions, where price signals are distorted, make the Māori relational approach to value assessment more rather than less relevant.↩︎
Bilateral clearing arrangements were used extensively in the 1930s–1950s, particularly by Germany under the Schacht system (1934 onwards), which maintained bilateral trade accounts with dozens of countries, settling trade through offset rather than currency exchange. The UK maintained similar arrangements through the Sterling Area. These systems were imperfect — they tended to create imbalances and reduce the efficiency of multilateral trade — but they functioned adequately when the international monetary system could not. See: Eichengreen, B. and Irwin, D.A. (2010), “The Slide to Protectionism in the Great Depression: Who Succumbed and Why?” Journal of Economic History 70(4), 871–897.↩︎
The eurozone’s structural problems are relevant as a cautionary precedent. Countries that shared the euro could not devalue their currency in response to country-specific economic shocks (as they could under their previous national currencies), which contributed to severe economic stress in Greece, Spain, Portugal, and Ireland during the 2008–2012 crisis. The lesson for any NZ–Australia regional currency arrangement: monetary sovereignty has real value under conditions of economic asymmetry. See: Stiglitz, J. (2016), “The Euro: How a Common Currency Threatens the Future of Europe,” W.W. Norton.↩︎
