The committee met at Papakura Marae, on the southern outskirts of metropolitan Auckland, about 1pm to discuss Mr Harawira's complaint against Mr Harawira.
Mr Flavell, the Waiariki MP and party whip, lodged the complaint after Mr Harawira wrote a newspaper column accusing his party of becoming too caught up in its coalition with National and supporting anti-Maori policies.
Mr Flavell put his side of the argument two weeks ago, but Mr Harawira did not use his chance to put his argument today, instead attending a Waitangi Tribunal hearing into the Treaty of Waitangi claim from his home iwi, Ngapuhi.
"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 committee had, and to provide any other statements and I've left it in their hands."
Mr Flavell said he thought Mr Harawira was not respecting 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 dealt with 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."
