Mr Harawira has already been suspended from the party's parliamentary caucus because of his outspoken criticism of its relationship with the Government which he says is passing anti-Maori legislation.
Mr Harawira's colleague Te Ururoa Flavell laid a formal complaint and after weeks of delays and numerous hui, the disciplinary committee said yesterday it had to resolve the issue.
"Accordingly, with great sadness and after many hours of deliberation...there did not appear to be any way of resolving the complaint besides cancelling Mr Harawira's membership of the Maori Party," it said.
The national council has to take the final step, and support for Mr Harawira is understood to be coming only from his fiercely loyal electorate committee.
Expulsion will mean he becomes an independent MP, sitting far away from his colleagues at the back of the debating chamber alongside former Labour MP Chris Carter.
Mr Harawira will then have to decide whether he wants to continue as an MP and contest the November 26 general election as an independent -- or form another party.
