Growing Up in New Zealand is New Zealand’s contemporary longitudinal study tracking the development of more than 6,000 New Zealand children from before birth until they are young adults. The study is designed to provide unique information about what shapes children’s early development and how interventions might be targeted at the earliest opportunity to give every New Zealand child the best start in life.
