Waikato-Tainui politician Tania Martin has been voted out of tribal office after the iwi's parliament voted in favour of a charge of bringing it into disrepute.
She had been the tribe's chairwoman of Te Kauhanganui or parliament but on Sunday 36 of 57 marae, which have three members each, agreed with the motion that also removed her.
In an extraordinary move last week the tribe's paramount chief King Tuheitia wrote to members asking that they remove Ms Martin, saying years of infighting had destabilised the tribe.
Ms Martin had been fired by the king in 2010 after she raised concerns about wasted tribal funds. The move proved to be outside of tribal rules and Ms Martin resumed her position.
In a statement today Tuheitia congratulated the institution for its decision. He said he hoped the decision would be accepted without recourse to "costly litigation" and "Paakeha courts".
