The Top Down Review of the Official Statistics System recommended that the Official Statistics Research and Data Archive Centre (OSRDAC) be established to provide:
- a metadata archive for all Tier 1 surveys, administrative data and integrated statistical datasets, and
- a unit record data archive for all Tier 1 surveys, and Statistics New Zealand's holdings of Tier 1 administrative datasets and integrated statistical datasets,
- including historical data (e.g. censuses of particular interest to researchers).

The data archive holds important unit record datasets from across the official statistics system and makes suitably confidentialised versions of these datasets available to researchers via Statistics New Zealand's microdata access services.
All versions of each dataset, along with their associated metadata and documentation are carefully managed to ensure long-term use.
Data archive content
The archive holds:
- metadata for all Tier 1 statistics,
- definitive versions of Tier 1 survey datasets
- other datasets of high quality that are of significant value to current research needs and anticipated future ones
- the metadata and documentation needed to manage and make informed use of each dataset
- confidentialised versions of datasets.
