NSW Premier Dominic Perrottet insists he is confident he has the backing of Liberal Party colleagues to continue as leader after again apologising for wearing a Nazi uniform to his 21st birthday party.
Mr Perrottet was on Sunday grilled about the incident after announcing a $1 billion package for road improvements in Western Sydney.
The premier again stressed his decision to wear a Nazi uniform was a "terrible mistake" but said he still had the backing of the party.
"I've had a significant amount of support from my colleagues," he said.
"I was naive and young.
"People know who I am as a person and they make their judgements on that."
Mr Perrottet was asked who attended his 21st birthday party but said he could not remember as it was a "long time ago".
"All I know was I was there and know what I did," he said.
"It's not about other people. I made a mistake."
The premier also played down suggestions people within the Liberal Party were trying to damage his leadership ahead of the state election in March.
"I'm not focused on the party or politics. I'm focused on taking the state forward."
NSW Minister for Metropolitan Roads Natalie Ward said the premier had her full support.
"What I've seen in Dom Perrottet is a compassionate kind person who works his guts out every day for the people of NSW," she said.
"Ultimately what he's done is he's owned this, he's stepped up he's answered questions and hasn't shied away from it."
Mr Perrottet last week disclosed that he wore a Nazi uniform to his 21st birthday party in 2003.
The premier said he only confessed to the "mistake" after a call from outgoing Transport Minister David Elliott.
In recent days, Mr Perrottet has apologised repeatedly at press conferences and in a video posted to social media — after first meeting with Sydney Jewish leaders following his disclosure.
Robert Borsak, leader of the NSW Shooters, Fishers and Farmers, questioned whether the premier's failure to disclose his "dirty secret" on at "least three occasions" was a breach of The Oaths Act, and called for his resignation.
"That three-page nomination form is a legally binding Statutory Declaration," Mr Borsak said in a statement.
"It is clear that the premier may have sworn a false oath on a number of occasions by not declaring that he had worn a Nazi uniform to his 21st birthday and if so could be subject to 5 years goal (sic).
"He has no integrity and must resign."
Mr Borsak is also calling on the Public Accountability Committee to urgently convene a hearing to examine the "fitness of Perrottet to remain as premier".
The NSW Liberal Party on saturday refused to confirm whether Mr Perrottet told them about the Nazi costume during his preselection vetting process in 2010.
In a statement, the Liberal Party told the ABC "the nomination process is confidential".
