New Zealand Health Survey

The New Zealand Health Survey (NZHS) provides information about the health and wellbeing of New Zealanders. The NZHS became a continuous survey in 2011, enabling the publication of annual updates on the health of New Zealanders.

COVID-19 update: The New Zealand Health Survey, which is administered by a face-to-face interview, was suspended in March 2020 to reduce any risks of transmitting COVID-19 between interviewers and respondents. The survey started again on 4 September 2020.
