Aotearoa - New Zealand's colonial history of subjugation from lands, cultural expression, traditional knowledge systems and language has Resultsed in abhorrent disparities in health outcomes for its indigenous peoples, Whilst some academic evidence (Dudley et al., 2019) exists that Te Reo Māori is a protective factor for health, it is well known within traditional knowledge systems, held within the proverb "tōku reo tōku ohooho" (My language, my deliverance) that language is a protective factor and a facilitator of wellbeing. 51 years after the Aotearoa Language petition, we are seeing the emersion māori language into white-stream settings. As the indigenous language of New Zealand shifts from a space of revitalisation to prosperity, there are risks associated with the vitality of the language, particularly within health. As new words are created with new technologies (e.g. vaping), and health messaging in te reo becomes critically necessary, there are numerous risks for the commodification of the language, and further challenges for the protection and prosperity of Te Reo Māori in the health sector. Te Reo Hauora looked firstly to collectivise the voices of all people leaning into the linguistic disposition of Te Reo Māori in health, sharing the aspirations and strategic thinking of people from all facets of society who have an impact on the way the Māori language prospers in health. This presentation will share the Findings of Hāpai's work in Te Reo Hauora, drawing on the project and its development, implementation and evaluation.
