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.
Confidentialised Unit Record Files (CURFs) are microdata that have been modified to protect the confidentiality of the respondents. CURFs can be useful for a wide range of exploratory research.
Information on how to apply, and pricing, is available on the Confidentialised unit record files web page.
Synthetic Unit Record Files (SURFs) contain synthetic data that mimic the characteristics of real microdata. Anyone may access SURFs free of charge. SURFs are useful for teaching purposes at secondary and tertiary levels.
More information is available on the SURF for Schools web page.
Visit our Microdata research page to find out which organisations are using our microdata and what projects they are using it for. The page also contains links to resources that researchers may find useful.
