This thesis takes a critical approach to the evaluation of Māori social and health service provision progammes through an in-depth exploration of the dynamics, impacts and politics of such exercises within Māori communities, and upon relationships between Māori and the Crown, and its agents. Since the mid 1980s, New Zealand government devolved responsibilities that heralded a change in economic focus and provided a pathway for targeted service provision, such as social and health programmes, amongst communities. The combined shift to Neoliberal economics and the virtual hegemony enjoyed by right wing economic commentators, policy-makers and business leaders meant that newly anointed Māori service providers were not fully prepared for the subsequent rise in demand for narrowly defined accountability requirements that did not reflect Māori aspirations or values. This study sought to critically engage with the experiences of stakeholders affected by an external evaluation of “By Māori, for Māori” services. Qualitative data capturing stakeholder narratives, demonstrated the complex relationships and range of emotions experienced by programme stakeholders. Four case studies contain stories that highlight: service provider relationships built on betrayal that contributed to programme tensions and influenced the design of the evaluation; different stakeholder information needs that shaped their expectation of an evaluation; service provider vulnerability when implementing cultural values with their funder, who then seeks financial gain from that knowledge, and; the close links of Kaupapa Māori programmes and their evaluations to socio-cultural and political agendas. The cases highlight ways Māori evaluators operated from a reflexive approach that recognised two worldviews (Mātauranga Māori and the dominant models of Western social science) and sought to facilitate engaged evaluation relationships with different stakeholders. A proposed Cultural Confluent Evaluation model lays out the dynamics and tensions in an attempt to make visible the underlying agendas, but also the glossed ideologies of power and control attached to conventional evaluations. As existing programmes continue to be examined for their cultural responsiveness, and as new culturally-centred programmes are proposed, the need for culturally embedded evaluation is even more evident.
