On the final day of the election campaign, he was once again standing outside Sydney's Allianz Stadium attacking the Berejiklian government's spending on sporting venues.

Mr Daley on Friday rejected any suggestion he'd focused too heavily on the issue and insisted he was "very hopeful" about his chances on Saturday.

The opposition leader has held six press conferences at Allianz Stadium in just over a fortnight.

He wants to refurbish the Moore Park venue rather than knock it down and rebuild it at a cost of $730 million.

Despite hard demolition works starting two weeks ago, Mr Daley insists it can still be salvaged.

"Only superficial damage has been done .... (there's) no dead horse here, the horse is very much alive," he told reporters on Friday.

"We're going to give it a refurbishment at no cost to the taxpayer and it will shine like a new pin."

The freshly minted Labor leader - who says he's had just two days off since taking over from Luke Foley in mid-November - has promised to make schools and hospitals his priority.

But he stumbled mid-week when he couldn't recall how much Labor was going to spend on schools and TAFE.

Earlier, on Monday, a video emerged of him telling a pub forum last year that skilled Asian migrants were taking local jobs.

"Sometimes you have a bad week, and I've had a couple of rough days this week," he admitted on Ten News.

Nevertheless, Mr Daley ended his campaigning on Friday afternoon in the western Sydney electorate of Penrith feeling "upbeat" and "really good."

He reiterated Labor's promise to re-introduce the M4 Western Motorway cashback and took aim at the coalition for reinstating tolls between Parramatta and Homebush in mid-2017.

The premier has spent considerable time in Penrith during the election campaign which is held by Liberal MP and Western Sydney Minister Stuart Ayres with a 6.2 per cent margin.

Mr Daley warned the premier about the "burden" Mr Ayres has brought to residents.

"The premier should be worried about losing Penrith because her member for Penrith, Stuart Ayres, has brought nothing but a burden to the people," he said.

The latest opinion polls suggested the parties were locked at 50-50 on a two-party preferred basis.

The NSW Electoral Commission on Friday said more than one million people had already pre-polled.
