Access our microdata

Statistics New Zealand provides access to microdata (data about specific people, households, or businesses) to support research.

Access to microdata is carefully managed to protect confidentiality. No information about individual people, households, or businesses may be published or disseminated.

More information is available on the Microdata access protocols web page.

Please contact us to discuss your research and to find the best microdata product for your project.

In-depth research using microdata

If you want to analyse more detailed statistics – at the level of individual people, households or businesses –- you can apply for access based on the requirements of the Statistics Act 1975. Approved researchers can work in our secure Data Lab.

Information on how to apply, and pricing, is available on the Data Lab web page.
