New Zealand: National climate change risk assessment (2026)

2026-NCCRA-Full-assessment presents New Zealand’s second national climate change risk assessment, undertaken by He Pou a Rangi Climate Change Commission. The report evaluates 37 climate-related risks affecting the country’s environment, infrastructure, economy, communities and governance systems, and advises government on the most significant risks requiring action through future adaptation planning.

The assessment finds that climate change is already affecting New Zealand through rising temperatures, sea-level rise, changing rainfall patterns and more frequent extreme weather events. Risks are expected to intensify across seven domains: natural environment, built environment, people and communities, Māori interests, economy and finance, sectors reliant on natural resources, and governance. The report identifies key infrastructure, ecosystems and biodiversity, Māori wellbeing, emergency management, social and community wellbeing, forestry, government finances and adaptation governance as priority areas for action.

The assessment emphasizes that adaptation requires long-term planning, coordinated governance and sustained investment. It also highlights the importance of addressing climate risks in ways that support Māori rights, social equity and community resilience while avoiding maladaptive responses that increase future vulnerability.
