The Greens NSW have denied infighting cost them votes in the weekend's election while vowing to try and isolate incoming upper house MP Mark Latham and his "racist" One Nation party.
Greens Legislative Council MP David Shoebridge on Sunday said the "rest of politics" needed to stay away from the former federal Labor leader.
"We will make sure Mark Latham is a sole and marginal voice in that place," he told reporters in Sydney.
"We will work with politicians from across the political spectrum to make sure One Nation's racist and divisive politics does not take root in NSW."
Mr Shoebridge and new recruit Abigail Boyd seem certain to retain the Greens' two vacant upper house seats while lower house MPs Jenny Leong, Jaime Parker and Tamara Smith all increased their margins in their seats.

Lismore candidate Sue Higginson conceded defeat about 10am on Sunday but celebrated Labor's Janelle Saffin becoming the seat's first female MP.
Statewide the Greens' primary vote in both houses appears to have dropped to its lowest level since 2007.
The Greens are down 0.6 percentage points in the Legislative Assembly to 9.7 per cent and 0.8 percentage points down in the Legislative Council to 9.1 per cent.
The Greens rejected suggestions their vote was harmed by infighting that led to upper house MP Jeremy Buckingham resigning in 2018 and deep division between the far-left and centrist factions.
Instead, the minor party pointed the finger at fellow progressive party Keep Sydney Open.
"The issues KSO were running on - opposing the lockouts, standing up for Sydney's nightlife - are issues the Greens have been running strongly on," Mr Shoebridge said.
"It is unfortunate that the KSO vote, I think, largely took votes from the Greens and largely took votes from the progressive side of politics."
Newtown MP Ms Leong said the Greens had been returned in her seat, Balmain and Ballina by focusing on key voter issues such as climate change action.
"While the media commentary was suggesting there were infighting and division to the point of crisis, (the lower house MPs) were out on the streets chatting to people," she said.
"These things did not impact our result.
"Any of the narratives that suggest there is some division between the inner city and the north (of the state) just does not hold true."
