There are 1130 patients in hospital with the virus, 59 of them in intensive care and 24 of them on ventilators.

Seven men and four women died, including one man in his 40s.

He had received three doses of a vaccine but had significant underlying health conditions, NSW Health says.

NSW Health reports 57.7 per cent of people eligible for a booster have now received one, while 94.3 per cent have had two vaccine doses.

More non-urgent elective surgery patients will be able to access services requiring an overnight stay in private hospitals from Monday.

NSW Health is lifting the cap to 85 per cent of pre-pandemic capacity in private hospitals before completely removing it on Monday, March 7.

Public hospitals are on track to perform up to 75 per cent of pre-pandemic elective surgeries or higher over the coming weeks, health authorities said.

"[The staged approach] ensures people have access to clinically recommended surgery while we continue to balance the COVID-19 emergency response," NSW Health acting deputy secretary Wayne Jones said.

Saturday's hospitalisation figures are less than half of the admissions around the same time last month when the omicron wave saw a peak of 2943 people in hospital with the virus.

However, the slow decline of hospitalisations sits in contrast with NSW Health's best case scenario of the omicron surge, which predicted that admissions would be well under 500 cases by now.

The latest figures come the day after mask mandates were significantly eased across the state with residents only required to use them in certain settings, including on public transport and in hospitals.

NSW Health's Dr Jeremy McAnulty says masks are still recommended in places where maintaining physical distance is challenging.
