Background The Aotearoa New Zealand population is ageing accompanied by health and social challenges including significant inequities that exist between Māori and non-Māori around poor ageing and health. Although historically kaumātua (elder Māori) faced a dominant society that failed to realise their full potential as they age, Māori culture has remained steadfast in upholding elders as cultural/community anchors. Yet, many of today’s kaumātua have experienced ‘cultural dissonance’ as the result of a hegemonic dominant culture subjugating an Indigenous culture, leading to generations of Indigenous peoples compelled or forced to dissociate with their culture. The present research project, Kaumātua Mana Motuhake Pōī (KMMP) comprises two interrelated projects that foreground dimensions of wellbeing within a holistic Te Ao Māori (Māori epistemology) view of wellbeing. Project 1 involves a tuakana-teina/peer educator model approach focused on increasing service access and utilisation to support kaumātua with the greatest health and social needs. Project 2 focuses on physical activity and cultural knowledge exchange (including te reo Māori--Māori language) through intergenerational models of learning. Methods Both projects have a consistent research design and common set of methods that coalesce around the emphasis on kaupapa kaumatua; research projects led by kaumātua and kaumātua providers that advance better life outcomes for kaumātua and their communities. The research design for each project is a mixed-methods, pre-test and two post-test, staggered design with 2–3 providers receiving the approach first and then 2–3 receiving it on a delayed basis. A pre-test (baseline) of all participants will be completed. The approach will then be implemented with the first providers. There will then be a follow-up data collection for all participants (post-test 1). The second providers will then implement the approach, which will be followed by a final data collection for all participants (post-test 2). Discussion Two specific outcomes are anticipated from this research; firstly, it is hoped that the research methodology provides a framework for how government agencies, researchers and relevant sector stakeholders can work with Māori communities. Secondly, the two individual projects will each produce a tangible approach that, it is anticipated, will be cost effective in enhancing kaumātua hauora and mana motuhake.

This article undertakes a close reading of the parliamentary debates associated with the topic of embryo cryopreservation in Aotearoa New Zealand. From our critical readings, we argue that there is a lack of transparency over the ethical reasons for enforcing a maximum storage limit. We demonstrate that arguments for the retention of this limit are associated (in New Zealand) with arguments based upon ‘build-up avoidance’ and ‘conflict avoidance’ as social goods based on Pākehā [New Zealander of European descent] cultural world views rather than identifiable universal ethical principles. We illustrate that the avoidance of embryo accumulation and related conflict was only achieved by the denial of indigenous spiritual and cultural concerns, while also shifting the ethical burdens of disposition on to clinic staff and those members of the public who protested against enforced cryopreserved embryo disposal. The Pākehā cultural concept of ‘tidy housekeeping’ emerges as a presumed ethical and social good in the New Zealand situation. This is despite abundant literature documenting the suffering created through forced decision-making upon disposition.

The majority of Indigenous health models do not directly acknowledge that health is a contested political space. Providing a Foucauldian analysis, this article suggests a function of biopower is to naturalise discourses such as the poor Māori health statistic to appear based on factual evidence and thus are apolitical. Employing Foucault’s triad of power—sovereign, disciplinary and biopower—to understand the genealogy of Māori health, this article proffers mana motuhake (Māori political self-governance) as an appropriate health analytic because it, first, identifies Indigenous health as political and, second, because it recognises the disempowering role that colonialism has played in relation to Māori biopolitical self-governance. Hence, we suggest Māori health will be enhanced by mana motuhake and that research underpinned by Indigenous agency and self-governance resists biopower. The article references two Ageing Well National Science Challenge–funded research projects because they innovatively fundamentalise mana motuhake and politics to Indigenous health.
