NSW Greens MP Cate Faehrmann has lashed her party, saying there's been a "hateful" campaign against her colleague Jeremy Buckingham, who's been asked to resign.

A NSW Greens MP has lashed out at the "destructive extreme left forces" in her party after members formally asked fellow MP Jeremy Buckingham to step down.

The Greens NSW State Delegates Council passed, by consensus, a proposal to request Mr Buckingham vacate his position on the ticket during a meeting on Saturday, weeks after he was accused of sexual misconduct.

It was agreed his presence would stop the party from campaigning effectively ahead of next year's state election, a statement said.

The MP has been the subject of a 2011 sexual harassment allegation re-aired under parliamentary privilege by factional rival Jenny Leong, although an independent investigation recommended no adverse findings against him.

He denies the alleged incident involving a party staffer and another claim by Ms Leong of intimidation.

Mr Buckingham on Sunday accused the council of abandoning grassroots democracy and due process, and of rewarding the "bullying and smearing behaviour" of his factional opponents.

When asked if he would be standing aside Mr Buckingham told reporters: "No."

NSW Greens MP Cate Faehrmann on Sunday lashed out against the party on Facebook, saying it had been infiltrated by "destructive extreme left forces who will stop at nothing to weaken those in the party".

She claims there has been a "hateful" campaign against Mr Buckingham who she says has been subject to "bullying and attacks".

Australian Greens leader Richard Di Natale last month also called for Mr Buckingham to resign, saying the issue had gone on for "far too long".
