Access to survey microdata

Microdata refers to unit record and aggregate data that can be collected through surveys, censuses or administrative processes. Once all identifying information about individuals has been removed or modified to protect individual information, the dataset becomes a Confidentialised Unit Record File (CURF).

How to access survey microdata

CURFs of Ministry of Health population surveys are potentially available to bona fide public-good researchers, government agencies, non-governmental organisations and district health boards. They are available only after the key survey results have been released, and subject to certain terms and conditions.

The Ministry of Health population survey CURFs have now been placed in the Statistics New Zealand Data Archive. Researcher access to these datasets is now managed by Statistics New Zealand.
