A mandatory tenancy code for commercial tenants and landlords will be introduced so both parties can negotiate financial terms during the coronavirus pandemic.
The reduction in business turnover is intended to be reflected in the rent waiver by the landlord.
The code was discussed in a national cabinet meeting on Friday, attended by Premier Peter Gutwein.
Earlier in the day, Mr Gutwein said it was important to allow businesses to hibernate so they could provide services and help the state's economy recover after the pandemic.
A person employed by a tour company in the North tested positive to coronavirus on Thursday night.
This was after they had hosted two interstate people, who later tested positive to coronavirus, during their trip to Tasmania last month.
Anyone with coronavirus symptoms in Devonport will be able to be tested, Public Health has said.
Deputy director Dr Scott McKeown said Public Health was continuing to trace the contacts of two people confirmed with the virus at Devonport.
"We are nearing the completion of those investigations in the community and there's also an ongoing investigation within the Tasmanian Health Service," he said.
"We're also implementing a process of testing in the community called sentinel testing, in which five general practices and the Mersey Community Hospital will undertake testing of anyone presenting with suggestive symptoms.
"To get a sufficient number of tests that will take into next week before we're able to provide publicly any information on our finding.
"If we do find confirming evidence of community transmission we'll respond earlier." The number of coronavirus cases daily has dropped to around seven per cent nationally and by five per cent in Tasmania.
Dr McKeown said the slowing of cases was encouraging. "Towards the end of last week and the weekend, we had a significant spike," he said.
"We're seeing now slowing of those cases and that's very reassuring for the Tasmanian community.
"Much of the driver of that are our very strong measures that we're putting in place. But I need to stress to the Tasmanian community, now is not the time to be complacent." Meanwhile, two people were charged with COVID-related offences on Friday.
A 40-year-old Goodwood man was charged with driving while disqualified, evading police, and failing to comply with the direction of the Public Health director to self-isolate.
A 46-year-old South Hobart woman was charged with driving while disqualified, using a controlled drug, driving an unregistered vehicle, and failure to self-isolate.
