The Government has signed an agreement to begin formal negotiations with Ngapuhi before the Waitangi Tribunal reports back on its inquiry into recognising the mandate of Tuhoronuku Independent Mandated Authority.
Treaty Negotiations Minister Chris Finlayson said he was confident the decision to recognise the mandate was correct.
"I look forward to the tribunal's report and will carefully consider its views, but in the meantime there is important work to be done."
He said he was making the announcement on the 20th anniversary of the signing of Tainui's Treaty of Waitangi settlement with the Crown - the first settlement.
"Tainui provides an excellent example of just what an iwi can achieve for its people post-settlement," he said.
