This report presents information and key results from the mental health and problematic substance use module of the New Zealand Health Survey (NZHS).

The New Zealand Health Survey (NZHS) included a module on mental health and problematic substance use (including tobacco, alcohol and illicit substance use) in 2016/17, 2021/22 and 2022/23.
Because of smaller achieved sample sizes in 2021/22 and 2022/23, data from these years have been pooled (combined) to produce more precise estimates. The combined data is referred to as 2021–23 data and has a slightly smaller sample size compared to 2016/17: 10,256 adults and 2,628 children in 2021–2023, compared with 12,929 adults and 3,733 children in 2016/17.
As mental health is a sensitive topic, and individuals may not be comfortable disclosing information about their use of illicit substances, respondents were able to self-complete the module on a tablet provided using computer-assisted-self-interviewing. The module for children was completed by the child’s primary parent or caregiver.
