The NSW Greens are a "rotten and corrupt" party, according to one of their own MPs, who claims a new review into the bitterly divided organisation is nothing more than a band-aid plastered over a "weeping wound".
The Australian Greens on Tuesday night agreed to support an internal review into the NSW branch's structures and processes following months of factional infighting.
Greens NSW co-convenor Sylvia Hale said the national resolution also backed calls by the state branch to request embattled NSW MP Jeremy Buckingham stand aside from the upper house ticket ahead of the 2019 election.
"Greens NSW is committed to bringing all Greens together and we believe the Australian Greens has a valuable role to play," Ms Hale said in a statement.
The review panel, comprising both state and national members, is expected to hand down its recommendations by August 2019.
Mr Buckingham, who is under pressure to resign over a sexual harassment allegation dating back to 2011 and is already in an unwinnable spot on the party's ticket, described the review as a band-aid solution.
"The resolution does not deal with the immediate issues of the party refusing to conduct a democratic recount should I leave the Greens ticket and capitulates to the extreme left who are running riot in the Greens," Mr Buckingham said in a statement to AAP on Wednesday.
"It's a band-aid on a weeping wound that is the rotten and corrupt NSW Greens party. This type of review happened only a few years ago and resulted in virtually no reform."
Mr Buckingham denies any wrongdoing in relation to the 2011 incident involving a party staffer and has pointed to an independent investigation that recommended no adverse findings.
Factional rival and Newtown MP Jenny Leong in November used parliamentary privilege to demand Mr Buckingham resign over the incident which she described as "sexual violence".
Ms Leong's move was described by others within the NSW Greens as an "orchestrated political hit".
