This paper will argue that the Treaty of Waitangi, signed on 6 February 1840 by Māori and the Crown, has a made significant contribution to informing and advancing Māori health practices in Aotearoa New Zealand. A key focus of this paper relates to (re)validating the Treaty to improve Māori health outcomes and providing a strategy for evaluating the current health status of Māori. There is a growing concern among Māori that the health sector continues to perpetuate notions of “treating” Māori health more so than empowering Māori to control their own processes for being healthy. Moreover, a major shift constitutionally (that is, self-determining the right to be healthy) as well as institutionally (that is, developing approaches to greater access to health provision) is required to enable Māori to achieve better health outcomes moving forward. Finally, a number of important culturally innovative, responsive and inclusive perspectives are shared to enhance our engagement with the Treaty and Māori health from a socio-cultural perspective.
