Scenarios
What-if analysis for NZ agriculture's possible futures
Scenario planning isn't prediction — it's preparation. These scenarios explore how NZ agriculture might respond to major shifts in trade, climate, regulation, and technology. Each scenario examines the triggers, impacts, and potential responses. The probabilities are subjective estimates to give a sense of relative likelihood; real uncertainty is much wider.
Key Variables
NZ agriculture's future depends on a handful of critical variables. Changes in any of these can cascade through the entire system.
China Trade
~$17B exports
Range: $8B – $25B
Carbon Price
~$35/NZU
Range: $20 – $150
Climate Impact
+1.1°C vs pre-industrial
Range: +1.5°C – +3°C by 2050
Water Regulation
NPS-FM under review
Range: Relaxed – Strict
Milk Price
$9.50/kgMS
Range: $6 – $12
Lamb Price
~$7.50/kg
Range: $5 – $10
Forestry Policy
ETS restrictions in place
Range: Banned – Open
Technology
Early adoption phase
Range: Slow – Rapid disruption
Scenario: China Trade Disruption
China Exports Fall 50%
Geopolitical tensions, economic collapse, or trade sanctions
Est. Probability
15%
China takes ~29% of NZ's food exports ($17B). A major disruption — whether from geopolitical conflict (Taiwan), economic collapse (property crisis deepens), or targeted sanctions (NZ aligns with Western bloc) — would be the largest trade shock in NZ history. The dairy and forestry sectors would be hit hardest.
Potential Impacts
- Dairy exports drop $8-10B; milk price falls to $5-6/kgMS
- Log prices collapse; forestry sector in crisis
- Farm values fall 20-30% as profitability drops
- Rural unemployment spikes; debt defaults rise
- NZD falls 15-20%; inflation from imports
- GDP contracts 2-4%; recession for 2+ years
Possible Responses
- Urgent FTA negotiations with India, UK, Middle East
- Government support packages for affected farmers
- Accelerate market diversification (ASEAN, Africa)
- Domestic processing investment (add value locally)
- Currency depreciation makes exports cheaper elsewhere
- Long-term: reduce China dependence to <20%
Precedent: Australian Wine
China imposed ~200% tariffs on Australian wine in 2020 over diplomatic tensions. Exports fell from $1.2B to near zero. Australian winemakers scrambled to find new markets. NZ saw this as a warning — if similar happened to dairy, alternatives don't exist at that scale.
Scenario: Carbon Price Hits $100+
NZU Price Reaches $100-150
ETS reforms, reduced free allocation, international alignment
Est. Probability
25%
The NZU price has swung from $85 (2022) to $35 (2025). If government policy tightens — reducing free allocation, linking to international markets, or agricultural emissions finally entering the ETS at full cost — prices could spike to $100+. This would reshape land use economics dramatically.
Negative Impacts
- Farming costs rise $50-100/ha from emissions liability
- High-emission farms become unviable without change
- Red meat exports face carbon cost disadvantage
- Processing costs rise (energy, transport)
Positive Impacts
- Carbon forestry becomes highly profitable again
- Incentive for emissions-reducing tech adoption
- Premium markets reward low-carbon producers
- NZ "clean green" brand strengthens globally
Scenario: Major Climate Event
Multi-Year Drought or Cyclone Cluster
3+ years of severe weather disrupts production nationwide
Est. Probability
20%
Climate change increases extreme weather frequency. A multi-year drought (like 2007-08 but worse) or cyclone cluster (like Gabrielle but repeated) could devastate production. Cyclone Gabrielle alone caused $1.5B in agricultural damage. Imagine 3 years in a row.
Potential Impacts
- Milk production falls 15-25%; mass culling in drought
- Horticulture regions wiped out (Hawke's Bay, Gisborne)
- Soil erosion, sedimentation, long-term land damage
- Insurance becomes unaffordable or unavailable
- Infrastructure damage (roads, bridges, processing plants)
- Food security concerns domestically
Possible Responses
- Expanded irrigation infrastructure (where water available)
- Drought-tolerant pasture and crop varieties
- On-farm water storage requirements
- Retreat from high-risk areas (coastal, flood plains)
- Government disaster funds and insurance schemes
- Regional diversification of production
Cyclone Gabrielle: A Preview
February 2023's Cyclone Gabrielle caused $1.5B in agricultural losses. Hawke's Bay orchards were destroyed — some won't produce for 5+ years. Entire vineyards buried in silt. This single event showed how quickly decades of investment can be wiped out. Climate models suggest such events become more frequent.
Scenario: Strict Water Regulations
Nitrogen Limits Enforced Strictly
New NPS-FM mandates 30-50% nitrogen reduction in key catchments
Est. Probability
30%
The science is clear: many catchments need significant nitrogen reduction to meet ecological bottom lines. If government implements strict limits (30-50% cuts in Canterbury, Southland, Waikato), intensive dairy in particular faces existential pressure. Some farms would become uneconomic at current intensity.
Potential Impacts
- Canterbury/Southland dairy stocking rates cut 30%+
- Farm profitability drops; some farms fail
- Land values fall in affected catchments
- Processing plants lose throughput; closures possible
- Rural employment falls in dairy-dependent regions
Possible Responses
- Shift to lower-intensity systems (organic, regenerative)
- Technology adoption (precision fertilizer, inhibitors)
- Land use change: dairy → sheep/beef or forestry
- Wetland construction for nitrogen capture
- Irrigation efficiency investments
- Catchment-level nutrient trading schemes
Scenario: Technology Disruption
Lab Meat & Precision Fermentation Scale
Alternative proteins capture 20%+ of dairy/meat market by 2035
Est. Probability
15%
Cultivated meat, precision fermentation dairy, and plant-based alternatives are advancing. If production costs fall below traditional farming and consumer acceptance grows, NZ's grass-fed advantage could erode. This is the slow-burn threat that could reshape agriculture over 20 years.
Threat Impacts
- Commodity dairy/meat prices fall as alternatives scale
- NZ's cost advantage erodes (can't compete with fermentation)
- Young consumers shift preferences away from animal products
- Export markets impose "sustainability" requirements
Opportunity Impacts
- Premium "natural/grass-fed" segment grows for affluent consumers
- NZ invests in alternative protein production itself
- Emissions pressure on traditional farming reduced
- Land freed for other uses (horticulture, forestry, restoration)
Precision Fermentation: Real Dairy Without Cows
Companies like Perfect Day use genetically modified yeast to produce real whey and casein proteins — molecularly identical to cow's milk. It's already in US ice cream. If costs fall, this could disrupt commodity dairy ingredients (milk powder, cheese) while premium fresh milk remains protected. Fonterra is watching closely.

Market diversification, land use flexibility, and technology adoption are the best hedges.
The Value of Scenario Planning
The point isn't to predict which scenario happens — it's to stress-test strategies against multiple futures. A farm, company, or policy that only works in one scenario is fragile. Robust strategies perform reasonably well across most scenarios. The question isn't "what will happen?" but "what should we do regardless of what happens?"
