The Maori Statutory Board says it has been excluded from debate on how Auckland Council spends its money.
John Tamihere, who represents the Maori Statutory Board, left a council committee meeting on Thursday, questioning the council's commitment to a partnership with Maori.
Mr Tamihere wanted to present a submission on what he considered to be the low level of spending proposed for Maori interests.
He was refused allocated speaking time, but invited to take part in the full budget debate.
Outside the meeting, Mr Tamihere said the board would consider other unspecified remedies, to have the council consider its position.
Radio New Zealand's Auckland correspondent says his move was the opening shot in what is shaping up to be a lengthy and heated debate over next year's rate rise and the council's 10 year budget.
