The Government has signed an agreement to start formal negotiations with Ngapuhi over what is likely to be the nation's biggest Treaty settlement.
But it is doing so before a Waitangi Tribunal report on a challenge to the mandate of Tuhoronuku Independent Mandated Authority from Ngati Hine-affiliated group Kotahitanga.
A start on the settlement, likely to be worth hundreds of millions of dollars, has been held up by division over who the Crown should be negotiating with.
However, Northland MP Winston Peters said the Government was now "frog-marching" a settlement and it would not work.
Treaty Negotiations Minister Chris Finlayson said he was confident the decision to recognise the mandate was correct.
