The first comprehensive assessment of adverse childhood experiences in New Zealand has suggested that prevention of childhood trauma, maltreatment, and family dysfunction remain important public health goals to support the wellbeing of children and adults. In this population-based study, 2887 (1464 female, 1423 male) participants were surveyed in 2019. At least one adverse childhood experience was reported by 55% of respondents before the age of 18 years, and 11.6% reported at least four experiences. A higher prevalence of adverse childhood experiences was reported by respondents who were younger, had lower socioeconomic status, and who identified as Māori. On multivariate regression analysis, exposure to any adverse childhood experience was significantly associated with later exposure to intimate partner violence and non-partner violence.
