NSW's premier has declined to criticise the Victorian government's decision to place the state in a five-day lockdown due to a COVID-19 hotel quarantine outbreak, saying "certain states have a way of doing things".
NSW in the 24 hours to 8pm on Sunday recorded no new locally acquired cases of COVID-19 for the 29th consecutive day.
Victoria recorded one new local COVID-19 case on its third day of lockdown, with the Holiday Inn Melbourne Airport outbreak reaching 17 people.
Premier Gladys Berejiklian said NSW would stick to its earlier position of treating widespread lockdowns as a last resort.
"Certain states have a way of doing things and NSW has a way of doing things. I think the way we dealt with the northern beaches cluster is the way NSW tends to deal with these issues," Ms Berejiklian told reporters on Monday.
"We avoid a lockdown at all costs, avoid closing our borders, allow our citizens as much freedom as we can while we're managing the virus.
"I'm not willing to say one system or one way of doing things is better than another, but what we have done in NSW to this point has worked well for us."
Ms Berejiklian also reiterated her stance that hotel quarantine workers around Australia should be the first to receive a COVID-19 vaccine.
The coronavirus vaccine rollout is set to begin on February 22 after the first doses of the Pfizer jab arrived in Sydney on Monday afternoon.
More than 142,000 doses are being taken to a secure location and batches will be assessed for damage and quality in the coming days.
Meanwhile, NSW Health said in a statement on Monday that those who have arrived in the state from New Zealand since February 6 should avoid high-risk locations and work from home where possible.
It comes after an outbreak of three new local cases in Auckland prompted a snap three-day lockdown in the city.
Anyone who has visited a COVID-affected site in New Zealand should also get tested and follow health directions, NSW Health said.
Ms Berejiklian on Monday also said NSW could not safely receive more than 3000 returned travellers in hotel quarantine per week.
