Updated social vulnerability indicators for 2023 now available

We have just released our 2023 social vulnerability indicators for climate-related hazards and natural hazards in Aotearoa New Zealand.

First developed in 2019, the indicators track how the New Zealand population’s vulnerability to natural hazards and climate-related hazards is shifting over time, to support better planning and decision-making. 

This 2025 update offers a fresh snapshot of both emerging pressures and areas of resilience across the country, highlighting where support is most urgently needed. 

While some trends are encouraging, such as improved access to internet and mobile phones and fewer homes affected by damp or mould, others point to deepening hardship for many households. 

The updated social vulnerability indicator data, based mostly on 2023 Census data, are now available for local communities across New Zealand. The indicators are relevant to a wide range of hazards, including extreme weather events (like floods, heatwaves and wildfires), natural disasters (such as earthquakes and tsunami) and public health emergencies (such as pandemics).

The SVIs offer a vital tool for councils, emergency services, government agencies and planners working to build more resilient communities. 

We will also launch an interactive online mapping tool later this year, allowing the public and organisations to explore vulnerability data in their area and track how it has changed over time.
