Welcome to GUiNZ

Growing Up in New Zealand (GUiNZ) is a longitudinal study that provides an up-to-date, population relevant picture of what it is like to be a child growing up in New Zealand in the 21st century.

Approximately 7,000 children and their families are taking part in the study that aims to provide a complete picture of the pathways that lead to successful and equitable child development, therefore improving outcomes for all children - now and into the future.

As the largest longitudinal study in New Zealand we are pleased to be working towards making positive change in policy and social outcomes.
