Ngati Kahu are pointing fingers at the Minister of Treaty Negotiations, saying he is the reason the iwi have not yet settled Treaty claims.
The comments come after minister Chris Finlayson told media Ngati Kahu needed to take a look at their current leadership if they wanted to progress their claims.
Mr Finlayson said a comprehensive offer was put in front of iwi and he urged leaders to consider what was best for Ngati Kahu.
But Te Runanga a Iwi o Ngati Kahu chairwoman Margaret Mutu said Mr Finlayson had no right to interfere with structures and that leaders were acting on the wishes of elders and hapu.
"I wouldn't order them to change the leader of the National Party," she said.
