Rates of noncommunicable diseases are steadily rising in New Zealand, particularly in Pacific and Maori populations. Of further concern is the increasing rates of related risk factors in children and adolescents. Therefore, a focus on prevention in research and interventions is key for the improvement of health and wellbeing. Literature shows that the adolescent life-phase is a highly influential intervention point for NCD risk reduction strategies as the persistence of dietary habits that emerge during this period continue into adulthood and can have intergenerational impacts. Thus, the aim of this study is to investigate the potential of a school-based intervention examining issues impacting nutritional practices to support adolescent and/or community-driven actions that promote positive nutritional behaviours. It is intended that outcome of this study will work to towards empowering adolescents to be agents of change in improving the health of their communities.
