The Māori Party says it's wrong that the most senior Māori leader at Oranga Tamariki is resigning from the ministry, and is calling for his boss to go instead. Hoani Lambert has resigned as the deputy head of Oranga Tamariki to take up a role at the Department of Internal Affairs. He insists his departure is not a protest against the agency's chief executive, Grainne Moss. Moss says the ministry is planning more partnerships with iwi. She also told RNZ Māori News Director Māni Dunlop she's open to the idea of working along side a Māori Chief Executive of Oranga Tamariki. The Waitangi Tribunal has been hearing from Moss as it investigates the ministry's role in uplifting Māori babies from their whānau. The urgent hearing follows several other inquiries into the removal of babies by, and the overall performance of, Oranga Tamariki. Dame Tariana Turia was at the Waitangi Tribunal yesterday. She speaks to Susie Ferguson.
