Significant investment is needed in Māori mental health and broader hauora/health services to address the high levels of psychological distress and promote positive Māori mental health outcomes. Mātauranga Māori inherently provides a holistic approach to understanding health and wellbeing that is often overlooked by dominant western models of mental health. Grounded in an indigenous Māori Psychology framework, this research will explore mauri tau as a Māori approach to wellbeing and emotion regulation. The rangahau aims to identify a broad range of practices that may be used to achieve mauri tau and wider applications of mauri tau in psychological practice, mental health, therapeutic settings and as part of everyday maintenance of health and wellbeing. Findings will be used to inform the development of a mauri tau framework.
