The 2019 NZ Family Violence Study builds on the work of the 2003 Violence Against Women Study and seeks to fill some of the information gaps not covered in the 2003 work.

The final sample size for this study was 2887 and consisted of 1423 men and 1464 women who completed interviews between March 2017 and March 2019. Read more about the methodology

This is the largest study of violence against women ever undertaken in New Zealand. It provides robust data on the prevalence and health consequences of violence. Conducted in 2003, the survey involved face-to-face interviews with 2,855 women from a random sample in the community.
The New Zealand Crime & Victims Survey (NZCVS) collects information about New Zealanders’ experience of crime. This has run every year since 2018 asking 8,000 New Zealanders from all walks of life about their experiences. The NZCVS has replaced the the previous New Zealand Crime and Safety Survey (NZCASS) series.
Findings from each cycle are published in reports, data tables, infographics and topic reports:
The first National Survey of the Health and Wellbeing of New Zealand Secondary School Students was conducted in 2001 by the Adolescent Health Research Group (AHRG), University of Auckland.

The survey was repeated in 2007, 2012 and 2019. Findings on violence are included in these reports.
