The high rates of rangatahi (Māori youth) suicide provide one of the starkest social and health disparities that exist between Māori and non-Māori. This project builds on a research activation grant that investigated coronial processes and how these can be enhanced by building and strengthening relationships with whānau affected by suicide. In the activation phase of the project, our examination of coronial files identified significant barriers to whānau engagement in coronial investigations. In this second phase, we will engage with whānau to collect and analyse whānau stories to understand how their involvement in coronial processes can be enhanced, and how they can contribute to suicide prevention. We will examine the multiple roles of people and agencies involved in coronial investigations and their contribution to rangatahi suicide prevention. The findings will contribute to policy adjustments in health and justice to enhance the delivery of Māori suicide prevention initiatives.
