There were 59,612 tests conducted in the 24 hours to 8pm on Sunday.
In the preceding 24 hours the state detected 296 fresh cases, with most coming from Sydney and the Hunter New England health district.
The deaths take the toll of the NSW outbreak that began in August to more than 500 people.
There are 474 people in hospital across the state with COVID-19 and 116 require intensive care.
84.8 per cent of the state's adult population is double vaccinated, with first doses at 93 per cent.
