NZ Health Survey 2024/2025 mental health and substance use data summary

This data summary brings together key adult mental health and substance use findings from the New Zealand Health Survey (NZHS) 2024/2025 focusing on our legislated priority groups.

The purpose of this summary is to provide a synthesis of key mental health and substance use findings from the NZ Health Survey. We want to maximise available evidence to drive improved decision making. Our aim is for this information to be used for planning and investment, and to direct resources where they are most needed to improve mental health and addiction outcomes.
