Now We Are Fifteen
Navigating life in mid-adolescence
Now We Are 15 shares new findings from Aotearoa
New Zealand’s largest longitudinal study as our young people move through middle adolescence. The information for this part of the study was collected in 2025 from more than 4,000 young people and their main caregivers, when they were around 15 years old and in Year 11 at school.
The 15-Year Check-In findings are presented across two snapshot reports exploring young people’s experiences of education, and their mental health and wellbeing. A third snapshot, focused on suicide and self-harm, will be published in early March. These snapshots offer valuable insights into life at age 15 and highlight the factors that shape learning, resilience, and connection during this important stage of development.
Two public webinars to share more detailed findings about the Now We Are 15 reports are being held in March.
Register for the Education webinar on 11 March here.
Register for the Health and Wellbeing webinar on 25 March here.
Data sets from the 15-Year Check Point will be available from April 2026.
Researchers and data users can apply for access to the data through the Growing Up in New Zealand data access process. A data access workshop will be held on the 31st of March 2026 to share more about the data available from the 15-Year Check-In and the data access application process. You can register to take part here.
