Mason K, Lindberg K, Haenfling C, Schori A, Marsters H, Read D, Borman B. Social Vulnerability Indicators for Flooding in Aotearoa New Zealand. International Journal of Environmental Research and Public Health. 2021; 18(8):3952. https://doi.org/10.3390/ijerph18083952

We published the report 'Social vulnerability to the impacts of climate-related hazards in Aotearoa New Zealand' in August 2024. This report presents results for individual social vulnerability indicators for New Zealand, including changes over time, maps by territorial authority, and differences by key population groups where possible. The social vulnerability indicators mostly draw on 2013 and 2018 Census data.

2023 social vulnerability indicators

The 2023 social vulnerability indicators were published in June 2025, and use mostly data from the 2023 Census.

The national surveillance report shows the social vulnerability indicators for New Zealand, over time.

2018 social vulnerability indicators

The 2018 social vulnerability indicators used 2018 Census data, and were published in 2020, updating the original indicators. These indicators have since been updated with the 2023 indicators.

The Story Map lets you explore interactive maps of the 2018 social vulnerability indicators.

2013 social vulnerability indicators

The original research project developed a set of social vulnerability indicators for flooding, using 2013 Census data.

- Social vulnerability indicators - heatmap and territorial authority summary (Oct 2019) (xlsx, 6.8MB): This Excel dataset provides summary indicator data by area unit and territorial authority, for the whole of New Zealand.  Indicator data are presented as summary 'heatmaps', to show indicators at a glance.  

- Social vulnerability indicators - full indicator dataset (Oct 2019) (xlsx, 37MB): This Excel dataset provides the full set of indicators, by territorial authority, area unit, and meshblock (where possible).  Data about population demographics, languages spoken, and population projections have also been included.  The indicator data is mainly from the 2013 Census. 

This research project included a case study for Porirua.  To explore the interactive online map of indicators, visit the Social Vulnerability Indicators Story Map for Porirua website.  

 

Research reports and user guides

The following research reports and user guides were published as part of the funded research project for developing the 2013 social vulnerability indicators for flooding.

As part of the research project, we identified ways of including social vulnerability into land use planning and local government, including District Plans.  The following report is available: 

  • pdficon small Incorporating vulnerability into land use planning (pdf, 1.5MB) (Oct 2019): This report identifies ways of including social vulnerability into local government processes, including land use planning, Annual Plans and Long Term Plans.  A case study of Porirua City Council is included, to give an example of how to include vulnerability into a District Plan.  This report was authored by James Beban and Sarah Gunnell (Urban Edge Planning Ltd), as part of the social vulnerability indicators for flooding project.
