A Maori Party disciplinary committee considering a complaint against Mr Harawira finished its meeting at Papakura Marae, on the southern outskirts of metropolitan Auckland, about 3.30pm today.
Committee chairwoman Te Orohi Paul said "a range of options" would be put to the party council on Wednesday, which would then decide whether Mr Harawira should be expelled.
It is believed a recommendation will be put to the council by the committee.
Mr Harawira did not turn up to the meeting today, instead attending a Waitangi Tribunal hearing into the Treaty of Waitangi claim from his home iwi, Ngapuhi.
His no-show disappointed the complainant, Waiariki MP and party whip Te Ururoa Flavell, who lodged the complaint after Mr Harawira wrote a column accusing his party of becoming too caught up in its coalition with National and supporting anti-Maori policies.
"Hone was provided one week with another week's extension to today to present his case. I came to listen to what he had to say and respect the fact that he came and listened to what I had to say ... but he's not here," Mr Flavell said after his meeting with the committee.
"I'm pretty disappointed about that, but I'm happy just to arrive, answer any questions that the committed had and to provide any other statements, and I've left it in their hands."
Mr Flavell said he thought Mr Harawira was disrespecting the process.
"It was his opportunity because he'd specifically asked for his opportunity to meet with the committee. I've waited for two weeks but I'm here and for my part it's important that I present myself and maintain the integrity of the process, which I think has been fair to all of us."
Mr Harawira has been a thorn in the side of the Maori Party's leadership for some time, especially after his newspaper column and his decision to give a "state of the Maori nation" speech at Waitangi Day celebrations shortly before party co-leader Pita Sharples gave an official one of his own.
The committee's recommendations are due to be put before the party's council on Wednesday. The party council will make the final decision on what sanctions Mr Harawira will face, and Mr Flavell said he hoped it would be shortly.
"I'd be pretty angry and pretty disappointed, personally, if it's not dealt with before the end of this week. I think we've had it too long. I think all of us want an end to it and we just want to get on and do the work."
