About the survey

Information collected through the New Zealand Health Survey supports the development of health services, policy and strategy. Survey data is collected continuously but findings are reported annually.

The results provide data for people selected for the survey period from July to June each year. Over 13,000 adults and the parents or primary caregivers of over 4,000 children take part in the survey each year. COVID-19 has impacted the collection of survey data in the last three years. The number of interviews for 2021/22 is about one-third of the usual sample size.

Access to survey microdata

Researchers can apply to access the Confidentialised Unit Record Files (CURFs) from Ministry of Health population surveys after the key survey results have been released.

CURFs have had all identifying information about individuals removed, and have been modified to protect individual information.

You can view a list of available CURFs at Access to survey microdata.

Researcher access to these datasets is managed through Statistics New Zealand. Go to Confidentialised Unit Record Files on the Statistics New Zealand website to view the eligibility criteria, the protocol for applying for access and the application form to access microdata.

Where respondents have given their consent for data linkage, the New Zealand Health Survey data has also been added to the Integrated Data Infrastructure which is managed by Stats NZ. Integrating the New Zealand Health Survey with other data sources enables rich insights to help provide better health care. Go to Integrated Data Infrastructure on the Stats NZ website to view the eligibility criteria, the protocol for applying for access and the application form to access microdata.
