Growing Up in New Zealand is this country’s largest longitudinal study of child development.

We visit our 6,000 participants and their families every three or four years and plan to do so until the study children are at least 21-years of age.

We gather information across six inter-connected domains:

  • Health and wellbeing
  • Psychosocial and cognitive development
  • Education
  • Family/whānau
  • Culture and identity
  • Societal context and neighbourhood environment

We have collected information from the cohort families – mothers, fathers and children at the numerous milestones.
