No date for NSW energy relief laws

The NSW government is keeping mum about when parliament will be recalled to pass laws empowering the commonwealth's proposed cost-cutting energy measures.

The federal government on Thursday passed legislation to introduce a cap on gas prices at $12 a gigajoule, introduce a mandatory code of conduct for the gas market and roll out power bill support for welfare recipients.

Premier Dominic Perrottet declined to commit to a day to recall the parliament to pass the legislation, which would allow the government to direct companies to cap its coal prices.

"I'll have something to say about that shortly," Mr Perrottet told reporters on Thursday, when pressed on a date.

The commonwealth plan will cost NSW hundreds of millions of dollars in lost revenue, the premier said earlier this week.

Meanwhile, members of the cross bench are being lobbied by the opposition as it looks to use proceedings to cut costs for renters, an approach the NSW Greens have called "astounding".

Labor began contacting members of the crossbench on Wednesday, seeking their support to recall the parliament on Friday.

Labor Leader Chris Minns has written to the premier, urging him to recall the parliament to address surging cost of living prices.

"Passing legislation would enshrine greater rights and more certainty for renters who are suffering from the cost-of-living crisis," he wrote.

Labor's plan to tackle rising rental costs includes banning secret bidding between prospective tenants and installing a rental commissioner to advocate for renters.

The policy was announced the same day the premier announced new regulations for real estate agents, banning rental auctions.

The government regulations will come into effect on Saturday.

Greens MP Jenny Leong wrote to Mr Minns on Thursday, telling him she found Labor's approaching "astounding" after the party blocked the Greens own rent relief bill earlier this year.

"Greens NSW MPs are always ready and willing to return to parliament if and when it is called," Ms Leong wrote.

"That said, we find it astounding that NSW Labor is now seeking to put this urgently on the agenda, when in the last sitting of parliament NSW Labor voted with the Liberal/National government to block the Greens motion to bring on our bill to end unfair 'no grounds' evictions."

The push for NSW parliament to reconvene comes amid a $22 million renovation of the chambers, with the red and green leather benches ripped from the chambers.

It's believed when recalled, both houses may sit consecutively in another, smaller room at parliament.
