It comes as four more cases have been confirmed in the state's north-west hotspot, bringing the state's total to 184.

Two of the cases are healthcare workers who have worked at the North West Regional Hospital, or the co-located North West Private Hospital in Burnie.

Both sites have both been closed due to coronavirus.

The third case is a former patient of the NWRH and the other is a close contact of a confirmed case.

One is aged in their 50s, one is aged in their 60s and two are aged in their 70s.

Test results are expected tomorrow on residents and staff at three north-west nursing homes where a healthcare employee worked before testing positive.

Earlier today a man died in the Mersey Community Hospital at Latrobe.

In a statement, Premier Peter Gutwein said he was deeply saddened to confirm the death.

"The 72-year-old man tragically has passed away this morning at the Mersey Community Hospital, where he was being cared for," he said.

"On behalf of the Government, I extend my deepest condolences to the man's family, friends and loved ones.

"This is another sad reminder that this disease takes lives, and we must do everything we can to contain the spread of coronavirus."

Mr Gutwein urged Tasmanians to "do the right thing, stay home and save lives".

The north-west is in the grip of an outbreak of coronavirus, with 10 cases confirmed on Thursday.

On Tuesday, a 91-year-old woman died at the Latrobe hospital due to coronavirus.

The emergency department at the NWRH reopened on Friday afternoon and will be staffed by Australian Defence Force personnel and members of the Australian Medical Assistance Team (AusMAT).

It will be open 24 hours a day using Defence Force labour while hospital staff are in quarantine.

Anyone attending is asked to wear a mask and report any coronavirus symptoms.

The hospital's workforce and their families are among more than 5,000 people in the region who have been put in mandatory quarantine for two weeks.

The latest coronavirus death comes after revelations a healthcare worker from the hospitals had also worked shifts at three aged care facilities in the region while infected.

Staff and residents at the three homes were tested on Friday.

Prime Minister Scott Morrison accused the worker of being dishonest about their contacts but the state's public health director said no "specific advice" had been given to his office about the worker.
