These venues include cafes, supermarkets, restaurants, retail centres, shops, schools, hospitals and aged care facilities.

Mr Gutwein said check-in requirements would remain in place at bars, pubs, clubs, gaming rooms, casinos, hotels and licenced venues for the time being.

He said the need to check-in to these venues would be reviewed over the next two to four weeks.

"And we'll also be looking at other restrictions, including masks in that period as well," Mr Gutwein said.

He said any further relaxation of check-in requirements would depend on new case numbers and case trends.

Mr Gutwein advised businesses no longer required to provide a check-in QR code should keep it in case they were required to use it in the future.

New South Wales and Victoria this week removed venue density limits and increased crowd capacity caps for events, despite high numbers of new COVID cases daily within the states.

Public Health deputy director Scott McKeown said Tasmania needed to be cautious about relaxing venue density limits and crowd caps so soon after schools had reopened.

"Those states are certainly making their decisions about their settings based on the pattern of the disease that they're seeing and also the stage in which they're at in terms of the opening of schools," he said.

"We're wonder one or two weeks behind those other states in terms of the reopening of schools and will continue to monitor the current pattern of spread in the community.

"We've always been cautious because we do know we have a higher proportion of our community that are vulnerable to COVID and we need to continue to protect members of the community that are more vulnerable."

Mr Gutwein said the government would discontinue the use of four Hobart hotels and Devonport's Edgewater Hotel as quarantine facilities by the end of March.

He said three Tasmanian hotels would be retained as quarantine facilities beyond then, including Peppers at Seaport in Launceston and Devonport's Sunrise Hotel.

These hotels will be kept in addition to COVID case management facilities around the state, Mr Gutwein said.
