Children's Commissioner Andrew Becroft accepted the report, and called it a "revolution".
"I think it is something of a blueprint for the way forward - we've talked a lot about this in theory but here's the foundation for a change in practice."
He said what made it achievable was Ngāti Porou's existing, well-resourced social services that were providing organic, wrap-around support.
He said changes to the law which required Oranga Tamariki to work with iwi, hapū and whānau also meant "there's never been a better time to grab this opportunity".
