Supporters of Maori Party MP Hone Harawira say they are worried about the way in which the party's national executive is dealing with him.
The party's disciplinary and disputes committee met on Friday to consider a complaint by party whip Te Ururoa Flavell, regarding an attack by Mr Harawira on its relationship with the National Party.
Te Tai Tokerau electorate chair Lisa McNabb says a hui at Whakapara on Thursday found the complaint to be baseless.
She says that by escalating the issue, the national executive has ignored the agreed on process and is wasting money on an expensive constitutional lawyer.
The party is reported to have allocated $25,000 for the services of Mai Chen.
However, the Maori Party says the complaint is too serious to resolve at the local level.
Disciplinary committee chair Te Orohi Paul says it is too late for another local hui, as offered by Te Tai Tokerau.
He says the committee will meet on Tuesday to decide the process before meeting both men on 9 February to resolve the issue.
