Available Data

Growing Up in New Zealand has conducted a number of data collection waves in which we have interviewed participants and their families face-to-face, by telephone or through online questionnaires.

Below you can see when we have collected information and via what methods.  You will also find links to the questionnaires used, links to the Data Dictionaries and links to Data Release User Guides.

It is a good idea to view these before lodging a request for data access to ensure that your research question can be answered by the data available.  You might also like to view the research projects currently underway or completed using Growing Up in New Zealand data.
