Ngapuhi leader David Rankin has fired a broadside at the Waitangi Tribunal, which he accuses of being a bully, inventing history and delivering New Zealand into apartheid.
Mr Rankin (Te Matarahurahu hapu) said it might surprise many New Zealanders, but a growing number of Maori were fed up with the Tribunal, and the entire "Treaty gravy train".
"There is a stereotype of Maori collecting millions of dollars in settlement money and living the easy life. The reality is very different," he said.
"The Tribunal makes up history as it goes along. A growing number of New Zealand historians are pointing this out, although most of them are labelled as racist for doing so. Facts are omitted in Tribunal reports, and evidence is shaped in some cases to fit pre-determined outcomes."
As an example, he had given evidence before the Tribunal about his ancestor Hone Heke, the first chief to sign the Treaty of Waitangi. However, because the whanau's oral history did not fit with the Tribunal's narrative, his testimony was excluded.
