The successful delivery of services and programmes by Māori and iwi providers is key to building Māori community capacity and therefore in addressing Mäori/non-Māori disparities (across, for example, health, education, employment, and the economy). It is also pivotal to Māori progress. This research sought the advice of Māori and Iwi organisations from across six sectors (housing, health, employment and training, social services, justice, education), about what had made them ‘successful providers’ of programmes and/or services over the past decade. The views of government agencies about Māori and iwi provider ‘success’ were also canvassed.
