NSW Opposition Leader Chris Minns has nudged ahead of Dominic Perrottet as the state's preferred premier in a new opinion poll.
The Resolve Political Monitor, published in The Sydney Morning Herald on Thursday, found 32 per cent of voters preferred the Labor leader, up from 23 per cent previously.
The Liberal premier trails at 29 per cent, while 39 per cent of voters are undecided, the poll of more than 1000 people found.
Mr Perrottet says it has been a difficult summer but he's not worried about polls.
"There will always be different polls at different point in time," he said.
"What I'm concerned about is the conversations that are occurring at every dinner table and that's getting kids back into schools safely, downward pressure on family budgets and building infrastructure," he told reporters on Thursday.
Mr Minns, who said winning the Bega by-election would be "almost impossible" for weeks before it happened, similarly downplayed the news, saying Labor "have got to climb Everest" to win next year's state election.
"I wouldn't be surprised if the NSW premier's ahead next month," Mr Minns said on Thursday afternoon.
He said the poll was a result of the Omicron wave and the government's management and there was a still a "rollercoaster" of a year ahead.
"At the end of the day NSW Labor are still the underdogs," Mr Minns said.
It's the first poll to test voter sentiment since the COVID-19 Omicron variant ran rampant in NSW over the summer holiday break and case numbers soared to tens of thousands a day.
Thousands of people in NSW were forced into isolation and testing centres were overwhelmed, while rapid antigen tests were in short supply and staff shortages were rampant.
The survey was conducted in the week after four by-elections on February 12, which saw the government lose the seat of Bega and suffer a swing of about 18 per cent in the blue-ribbon Liberal seat of Willoughby.
The final results won't be confirmed until March 11 but the coalition has already been pushed further into minority government.
The "Super Saturday" by-elections were the first major electoral test for the state's new major party leaders ahead of the next state election in March 2023.
The poll was conducted before the shutdown of the state's rail system on Monday, which has left the government in turmoil arguing over who was to blame, as train services continue to run at just 25 per cent capacity.
The poll found the coalition's primary vote also slipped - to 37 per cent, from 41 per cent - while Labor's primary vote increased to 34 per cent.
The Greens' primary vote has dropped to eight per cent, while the vote for independents rose to 13 per cent.
Resolve director Jim Reed told the SMH the poll showed voters weren't happy with the way the government had handled the Omicron outbreak.
"Given the poll was taken before the recent train shutdown and tolls debate, voters are telling us that this is mainly about the government's handling of Omicron," he said.
