Hone Harawira still hasn't decided if he will attend a hui in Rotorua today where a complaint against him could be discussed.
"I am unsure at this point in time," Mr Harawira told NZPA just after 8.30am.
He said he had a flight booked but was waiting to hear from people he declined to name before making a decision.
Mr Harawira and fellow MP Te Ururoa Flavell were invited to the hui at Rotorua's Taheke Marae. The Maori Party national council hoped the men could resolve the complaint laid by Mr Flavell over a newspaper column in which Mr Harawira said the party was too wrapped up with National and was supporting anti-Maori policies.
A hui held in Mr Harawira's Te Tai Tokerau electorate last week was supposed to resolve the complaint, but neither Mr Flavell nor party president Pem Bird were invited and it turned into a support rally for the MP.
The party's national council referred the complaint to the disciplinary committee, which has scheduled a meeting for February 9.
Today would be a chance for the two MPs to resolve the issue.
"They have not had a chance for a face-to-face . . . we've got the hearing on the 9th, this is a final opportunity for that," Mr Bird told NZPA yesterday.
He said Mr Flavell had been "the forgotten man" throughout the process so far.
"He's the critical person in this and was never invited to the hui," Mr Bird said.
"People have passed judgement on it without the people directly involved with the complaint."
The uncertainty surrounding Mr Harawira's future has heightened speculation that he could be the catalyst for the formation of a new left-wing political party.
Former Green Party MP Sue Bradford has confirmed she has talked to several left-wing activists - although not directly to Mr Harawira - about the possibility of a new party being formed.
Mr Harawira would be a crucial element of it, because he has strong support in Te Tai Tokerau and would very likely win the seat at this year's election, either standing as an independent or as the leader of a new party.
That would mean a new party would not have to gain 5 percent of the party vote to have MPs in Parliament.
