Bushfire tributes begin NSW sitting year

The first parliamentary sitting week in NSW will be dedicated to commemorating the bushfires

The NSW parliament will begin the sitting year by paying tribute to those who have been impacted by this season's unprecedented bushfires.

Politicians will return to Macquarie Street on Tuesday after a devastating summer of fires but parliamentary business will be suspended during the first week to allow each MP the chance to express sympathy for bushfire victims.

"This is the largest natural disaster in our state's living memory so it is fitting that the NSW parliament takes the time to reflect on this tragedy while also acknowledging the ongoing threat the fires pose," Premier Gladys Berejiklian said in a statement.

Some 2400 homes have been destroyed while more than five million hectares have burned in NSW this bushfire season.

"We know the trauma is widespread as people come to terms with the extent of the devastation," Ms Berejiklian said.

Bega MP Andrew Constance, who in January temporarily stepped back from his duties as transport minister to help his bushfire-ravaged electorate, will return to parliament on Tuesday but won't resume his cabinet duties until next week.

A state memorial service for the 25 people who have died in the fires this bushfire season will be held in Sydney on February 23.

Proposed building reforms will be among the issues NSW MPs are expected to discuss when they resume parliamentary business next week.

The reforms, which include a star rating system to identify and block high-risk builders with bad track records, are tied up in the contentious Design and Building Practitioners Bill.

The bill has been blocked in a previous form by Greens MP David Shoebridge and the Labor opposition, who voiced concerns at the time about it being full of "empty promises".

It is expected to be brought back to the upper house for debate on February 25.

Better Regulation Minister Kevin Anderson urged Labor and the crossbench to "put consumers ahead of politics" and pass the bill.

"Every day these reforms are delayed is another day homeowners go without the necessary protections," he said in a statement to AAP.
