Integrated Data Infrastructure

Note: 23 April 2019

We are in the process of migrating some of this content to our new site. See new links:

The Integrated Data Infrastructure (IDI) is a large research database containing microdata about people and households. Data is from a range of government agencies, Statistics NZ surveys including the 2013 Census, and non-government organisations. The IDI holds over 166 billion facts, taking up 1.22 terabytes of space – and is continually growing. Researchers use the IDI to answer complex questions to improve outcomes for New Zealanders.
