Surveys

2019 NZ Family Violence Study

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. Findings from the 2019 survey provide new population ‘baseline’ statistics on the prevalence of violence exposure. 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
