Wellington - New Zealand is facing a growing climate-adaptation challenge: the country has spent overwhelmingly more on responding to and recovering from natural disasters than on reducing the risks before disasters strike.
Research commissioned by insurer IAG found that the New Zealand Government spent at least NZ$19 billion responding to natural hazards since 2010, while a further NZ$14 billion was spent through public insurance schemes. Including private insurers, the total cost of natural hazards reached approximately NZ$64 billion over the period.
The most striking figure is the spending imbalance. About 97% of government expenditure examined in the research went toward disaster response and recovery, while only 3% was directed to risk reduction and resilience. The spending includes the enormous costs associated with the Canterbury and Kaikōura earthquakes as well as the devastating North Island weather events of 2023.
The figures are not exclusively a measure of climate-change spending, and the 97:3 ratio includes major earthquakes. Therefore, it would be misleading to describe all of this expenditure as climate-disaster spending. However, the imbalance provides a powerful illustration of New Zealand's broader challenge: too much public money is being committed after disasters occur, while investment in reducing future vulnerability remains comparatively small.
Climate risks are accelerating
New Zealand's latest 2026 National Climate Change Risk Assessment, released by the Climate Change Commission in May, identifies significant risks to infrastructure, communities, ecosystems, the economy and essential services. The Commission says people across Aotearoa New Zealand are already experiencing increasing disruption from storms, heavy rainfall, landslides, drought and sea-level rise.
The Commission has warned that damaging storm events have become substantially more frequent, with its chief executive noting that events occurring around once a month 15 years ago are now occurring closer to once a week.
The warning comes as New Zealand continues to deal with the financial consequences of major recent disasters. The 2023 North Island severe-weather events alone placed billions of dollars of costs on the government and economy.
Adaptation is still falling behind
The country's latest assessment of its National Adaptation Plan, released on 11 August 2026, provides another warning. The Climate Change Commission concluded that nationwide adaptation is not keeping pace with growing climate risks.
Although some progress has been made, the Commission says significant gaps remain in funding, governance, planning and climate-risk information, leaving communities exposed to greater damage, disruption and costs.
This means New Zealand faces a difficult financial cycle: extreme events cause damage, governments and insurers pay for recovery, infrastructure is rebuilt, and communities remain exposed to future hazards unless stronger measures are taken to reduce the underlying risk.
Why prevention is difficult
Risk reduction requires governments and communities to invest before disaster strikes-through stronger infrastructure, improved flood protection, better land-use planning, resilient roads and utilities, coastal adaptation, improved hazard information and, in some highly exposed areas, potentially moving people and infrastructure away from dangerous locations.
Such investments can be politically and financially difficult because their greatest benefit may not be visible for years.
Yet the economic argument for prevention is becoming increasingly compelling. IAG's research cited international evidence suggesting that every dollar invested in risk reduction can potentially reduce future response and recovery costs by about four dollars.
A warning for the future
New Zealand's experience illustrates a wider global problem: governments frequently mobilise enormous resources once a disaster has occurred, while preventive investment struggles to compete for funding during periods when no emergency is immediately visible.
The Climate Change Commission is therefore calling for earlier, coordinated action on the country's highest climate risks. Its 2026 risk assessment argues that acting sooner can reduce the multi-billion-dollar costs associated with delaying resilience measures.
For New Zealand, the challenge is no longer simply responding effectively when floods, storms, landslides or other disasters occur. The bigger question is whether the country can shift from a culture of recovery to a stronger culture of prevention and resilience.
As climate hazards intensify, continuing to rebuild after every disaster without sufficiently reducing exposure could leave taxpayers, insurers, businesses and communities facing an increasingly expensive cycle of damage and recovery.
The lesson is clear: rebuilding after disaster is essential-but investing before disaster strikes may ultimately be the far less costly option.
