The party's disciplinary committee met for a final time in Auckland yesterday to consider what action should be taken against Mr Harawira following a newspaper column accusing his party of becoming too caught up in its coalition with National and supporting anti-Maori policies.
The committee will take its recommendation tomorrow to the party's national council, which will decide if Mr Harawira will stay with the party.
Mr Flavell, the MP for the Bay of Plenty constituency of Waiariki and the party's whip, said he'd known Mr Harawira for 40 years and didn't make the complaint lightly.
"I'd have to say that no one has come up to me face to face and said 'we think you did the wrong thing'," he said.
"In fact, a lot of people have said Paati Maori, carry on, stay strong, continue the work that you're doing, and with that I take it that we're on the right track."
Mr Flavell acknowledged there were conflicts within the party but he was confident it would be strong no matter what the outcome of the disciplinary procedure.
"We've got a huge support base, a lot of elderly people who've done the cake stalls, who look after us on the road, who take us in and look after us as MPs, and support the cause of the Paati Maori," he said.
"They may not necessarily agree with every decision we make but they believe in us and that belief is really important to all of us and so we want to do right by them.
"Sure there's going to be whatever the outcome, there might be some fallout, but I know the Paati Maori's bigger than that and that we're going to continue on to be in an even stronger position after this.
Mr Flavell yesterday attended the disciplinary committee meeting hoping to hear Mr Harawira's version of events, but found Mr Harawira instead attended a Waitangi Tribunal hearing into the Treaty of Waitangi claim from his home iwi, Ngapuhi.
"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. I'm pretty disappointed about that," Mr Flavell said.
"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 Flavell added he would be angry and disappointed if the issue was not decided finally on Wednesday.
"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."
