3 patterns.
Agricultural sector climate exposure and adaptation pressure
New Zealand's primary sector faces intensifying climate exposure through drought, flood, and temperature change that threatens production systems, water availability, and farm viability across all primary-dominated regions.
Exposure profile
Pastoral farming in Canterbury and Southland faces increasing drought frequency. Horticulture in Hawke's Bay and Gisborne faces cyclone and flood risk. Dairy in Waikato faces both drought and water allocation pressure. Each primary sector has a distinct but intensifying climate exposure profile.
Adaptation pathway
Farm-level adaptation — irrigation efficiency, crop diversification, soil carbon, insurance — can manage some risk, but the upper bound of adaptation without transformation is below the projected climate trajectory. Systemic farm system change — including emissions pricing — is necessary for long-run sector viability.

Compound climate and seismic hazard exposure
New Zealand's unique position on tectonic plate boundaries combined with Southern Ocean weather systems produces compound hazard exposure — earthquake, flood, storm, sea-level rise — that is greater than the sum of individual risks.
Compound risk
A major Alpine Fault earthquake could disrupt the national economy for months. Combined with sea-level rise accelerating coastal erosion, increasing storm intensity, and drought frequency, New Zealand's physical environment presents compound rather than sequential hazards that standard risk assessment tools underweight.
Infrastructure exposure
Infrastructure designed and costed for single-hazard scenarios is typically under-built for compound events. Cyclone Gabrielle demonstrated this: roads, bridges, and stormwater infrastructure built to flood standards were overwhelmed by the combination of cyclone intensity and saturated catchments.

Low adaptive capacity in economically disadvantaged regions
Regions with high climate exposure and low economic capacity face a double burden: the most physically exposed communities are least able to fund adaptation, whether through private investment or local government infrastructure.
Double burden
Climate risk and economic capacity are inversely correlated in New Zealand's regions: Northland, Gisborne, and the West Coast face high physical exposure (coastal flooding, cyclone, erosion) while having limited fiscal capacity for adaptation infrastructure. This is the opposite of the distribution required for effective adaptation.
Crown transfer required
Market and local government mechanisms cannot close the gap between climate exposure and adaptive capacity in disadvantaged regions. Climate adaptation financing — analogous to the Cyclone Gabrielle Recovery Fund — needs to be structural and anticipatory rather than reactive.
