Premier Gladys Berejiklian announced the changes on Sunday. They will come into play on Friday, a full week after Prime Minister Scott Morrison revealed a three-stage plan to ease lockdown measures across Australia.

Ms Berejiklian said the Friday deadline would give people time to absorb what the rules meant, businesses to adapt and the government time to adjust laws that had penalised people out and about during the pandemic.

It's up to individual states and territories to decide when they act on the national cabinet position.

Currently, two adults from the same household, along with their dependent children, can visit another home in NSW under the existing COVID-19 restrictions.

"The changes will allow NSW to fire up the economy, while allowing more personal freedoms," Ms Berejiklian told a Sydney newspaper.

The new relaxing of restrictions to be announced by the premier will also allow 10 guests at weddings, 20 people at indoor funerals, and 30 at outdoor funerals.

Religious gatherings and places of worship can also welcome up to 10 people.

Outdoor equipments including gyms and playgrounds can be used with caution, with people encouraged to sanitise the equipment, and swimming in outdoor pools will be allowed.

Ms Berejiklian said some cafes and restaurants who were unable to adhere to social distancing within their premises or those that were not viable with a maximum capacity of 10 patrons may not reopen.

Travel between regions is still off the table.

It comes as NSW's health minister says the best people can give their mums when visiting on Mother's Day is to keep them safe by maintaining social distance.

Brad Hazzard has implored people to take care when visiting their loved ones on Sunday during the ongoing coronavirus crisis.

"Keep your mum safe," the minister said on Saturday.

"When you go to visit your mum, do what we have asked you to, which is to keep that social distance.

"I know it's really tough ... to not be able to hug or kiss your mum but it would be the wisest course."

Mr Hazzard said people could visit and enjoy their mother's company from a safe distance. But, of course, anyone feeling ill should stay at home, he added.

"No vaccine means we are still vulnerable and we need vigilance."

Mr Hazzard on Saturday stressed NSW eateries couldn't reopen for table service just yet.

"No-one should be sitting at a table or chair in NSW - it's pretty simple," he said.

"Right now there is no relaxation (of the state rules)."

"People are just bursting at the seams to get back, but I'd say be careful in what you wish for, because while that virus is still among us we are all vulnerable."

Five NSW cases of COVID-19 were announced on Saturday including one person who was exposed overseas and two from known close contacts.

The other two cases are still under investigation.
