There is growing international interest in racism as a determinant of health for young people. However, very little is known about the realities and health impacts of racism for rangatahi Maori. The potential for anti-racism interventions to improve rangatahi health, including mental health, has also been neglected. The proposed mixed-methods study will use a tikanga Maori co-design approach to reveal the realities of racism for rangatahi in Aotearoa (10-24 years). Rangatahi will be involved as collaborators, facilitators and participants in this research. The objectives are: (1) to identify and define the problem of racism, including consequences for health and wellbeing, and; (2) to develop, test, and refine rangatahi anti-racism solutions This innovative research will identify the essential elements and scope the parameters of effective anti-racism interventions in Aotearoa. Prototypes and online resources will be developed for use by community advocates, and findings shared directly with key policy makers.
