Operation Stay At Home will begin at 12.01am on Monday, with an extra 1400 highway patrol officers hitting the road across the state and another 500 Australian Defence Force troops - aside from the 300 already deployed - to help police enforce the public health orders.

Deputy Commissioner Mick Willing, the NSW Police Regional Field Operations commander, said 529 fines for breaches were handed out in NSW in the 24-hours to Sunday and 29 people were charged overnight on Saturday.

"We need 100 per cent of people to stay at home and comply with the public health orders - not 90 per cent, 100 per cent," Deputy Commissioner Willing said.

"Police don't want to have to enforce these additional orders, these additional powers, but we will and we make no excuse for that.

"Please stay at home, protect your loved ones, protect your family - do it for them, do it for NSW and we can reverse the trajectory of the current variant."

Operation Stay At Home is being coordinated from the Police Operations Centre in Sydney under the command of Acting Assistant Commissioner Andrew Holland.

The increased powers come along with the introduction of tighter restrictions in the wake of the start of a statewide lockdown across NSW.

Police and Emergency Services Minister David Elliott said the government was supporting a call for more powers from NSW Police Commissioner Mick Fuller.

"The Commissioner asked for tighter Public Health Orders and the government agreed, the Commissioner asked for higher fines and the government agreed, and the Commissioner asked for more ADF personnel and we have an additional 500 highly-trained ADF personnel arriving to assist," Mr Elliott said.

"We've had to tighten the current public health orders because of the minority who exploited them."
