Sydneysiders wanting to ring in the New Year by enjoying the fireworks at Sydney Harbour will need a ticket at a venue or will face being fined by police officers.

According to NSW Premier Gladys Berejiklian, police will have their eye on people attempting to enjoy the fireworks in the CBD.

"In terms of the public spaces where normally thousands and thousands congregate that won't be happening this year," Ms Berejiklian said.

"Unless you have a booking in a restaurant or cafe, please do not expect to go to the CBD for New Year's Eve.

"We do have to put strict rules in place but if some people choose not to respect the rules police will need to act."

As a special thank you to frontline COVID health workers and firefighters, some areas to view the fireworks will be set aside.

The 9 pm family-friendly fireworks have been cancelled, with only the midnight showing going ahead.

Office spaces where employees are able to get together in a COVID-19 safe space to enjoy the fireworks is also permitted.

The Premier has recognised celebrating will be a bit different this year.

"The vast majority of us will be enjoying celebrating New Year's Eve from home this year or at a restaurant, café or hotel and I think that is the best way. It's enjoying welcoming in the New Year in a COVID-safe way," Ms Berejiklian said.
