Climate adaptation, vulnerability and community well-being

Every regional council in the country, and over a quarter of our local councils, face extreme exposure to climate hazards like coastal erosion, flooding and rising groundwater levels. This research establishes a community development framework for the way we adapt and make decisions about climate change. Over the coming years, communities will have to make... Read more »...

Climate change and the withdrawal of insurance

Slow and sudden onset thresholds for private insurance retreat under climate change in New Zealand Coastal hazards are escalating with climate change. In particular, coastal homeowners can expect both sea level rise and more frequent and intense coastal storms. However, we continue to see demand for housing through new coastal residential development and intensification of... Read more »...

How should the risks of sea-level rise be shared?

We are used to thinking of natural hazards as unpredictable, one-off events like earthquakes. And our legal and policy framework is set up for such sudden and unpredictable natural hazards. But sea-level rise policies should not be like natural hazard policies, because sea-level rise is locked in and gradual. Even if we stopped all greenhouse... Read more »...

Sea level rise, housing and insurance: Liability and compensation

This project looked at the question of sea level rise and insurance. It investigated the “tipping points” at which insurance companies might decide to refuse insurance to coastal property owners, and asked, what will happen next? To what extent can or should homeowners rely on the EQC, or on local or central government, to compensate them if their... Read more »...

Extreme weather, climate change & the EQC

Earthquakes might not yet be predictable, but increasingly, climate change is. Because of climate change, extreme weather events in New Zealand may be getting worse and happening more often. What does this mean for our state-owned provider of natural hazard insurance – the Earthquake Commission (EQC) – and for the communities and regions directly affected... Read more »...

Flood mitigation schemes: are they working in flood-prone areas?

Flooding is the most economically damaging natural hazard in New Zealand. Since 2014 there have been over $300 million of insurance claims for flooding damage to homes, farms and infrastructure. Costs will increase as climate change continues to cause more flooding, and urban development intensifies in floodplains. This research explored several important and new research questions related to... Read more »...

Risk-based flood insurance pricing

Consequences, adaptation and policy in a changing market The property insurance market faces multiple stressors from increasing hazards, including floods, sea level rise and landslips. Concerns are emerging about the long-term viability of coastal insurance. It’s increasingly understood that insurers will turn to risk-based pricing to maintain coverage. On the one hand, this does encourage adaptation and better aligns payment with those...

National flood risks & climate change

Emergent exposure of flood inundation hazards under future climate change in New Zealand Floods are some of New Zealand’s most frequent, most damaging and most disruptive natural hazards. As our climate changes, flooding caused by both increased rainfall and rising sea levels – in coastal areas and on floodplains – is expected to increase. As... Read more »...

Climate impacts on the national water cycle

National hydrological and water resource impacts of climate change This century, climate change will alter New Zealand’s natural water cycle significantly. It will change how much rain and snow we receive, and at what time of year. It will change how much water is stored in the soil, snow, glaciers and aquifers. It will change... Read more »...

Climate change impacts on NZ electricity

Simulation of climate change impacts on the New Zealand energy system Electricity underpins every facet of our lives, and impacts our social and economic well-being. Climate change is expected to cause significant changes to both the demand and supply sides of electricity. Both government and industry are alive to the importance of balancing the “energy trilemma”... Read more »...
