Maori Party whip Te Ururoa Flavell says Hone Harawira has disrespected the party's disputes process by failing to show up for a meeting.
The party's disputes and disciplinary committee has finished a second day of meetings into Mr Flavell's complaint about the MP for Te Tai Tokerau.
The complaint was laid following comments Mr Harawira made in a newspaper article criticising the Maori Party's relationship with the Government.
Mr Harawira put in his apologies, saying he is busy with the Ngapuhi tribe's Waitangi Tribunal claim.
Mr Flavell says Mr Harawira had agreed to meet again with the committee and should have turned up to the three-hour meeting at Papakura Marae in South Auckland on Monday.
Committee chairperson Te Orohi Paul says it is now in a position to make a recommendation to the Maori Party's National Council - but would not say what it will be.
Ms Paul said the meeting was warm, but hugely difficult, and would not divulge what the committee's recommendation would be.
The council will meet on Wednesday when an announcement on Mr Harawira's fate is expected to be announced.
Mr Harawira has already been suspended from the party's caucus.
Possible sanctions range from censure to expulsion.
