This narrative review examines the intersection of gambling harms and stigma among Māori, Pacific peoples, Asian communities and youth in Aotearoa New Zealand. The literature shows that stigma is shaped less by individual behaviour than by structural factors such as colonisation, socio-economic inequities, migration pressures and the concentration of pokies in low-income communities. We identify how stigma is experienced within each population and how it influences help-seeking, highlighting the central role of identity, cultural obligations and collective wellbeing. The review synthesises culturally grounded strategies for destigmatisation and emphasises the importance of community-led approaches by lived experience. A key finding is the uneven distribution of research across priority populations: Māori receive the least contemporary research despite experiencing the highest rates of gambling harm. By weaving these insights together, the review informs the development of equitable, culturally aligned initiatives to reduce gambling harm in Aotearoa.
