This article presents the developmental stages of a nationwide whole-school strengths-based behavioural intervention by Maori and centring on Maori interests; an initiative that has the potential to transform educational success and opportunities. The initial phase involved a cycle of data collection. This was conducted via a series of focus groups held with Maori specialists, practitioners, families and students, to support the development of a kaupapa Maori approach to school-wide positive behaviour. The evidence that was gathered indicated that a systems framework needed to emanate out of a Maori worldview, be inclusive of family and community, and support the notion that Maori children are able to learn as Maori--to enjoy positive cultural and identity development throughout their schooling. The findings in this article describe the core features that underscore how behaviour should be shaped and supported within schools, from a Maori perspective.
