Prime Minister Jacinda Ardern and Dr Ashley Bloomfield give an update on coronavirus with six more cases on Wednesday.

An Invercargill woman who had been in the intensive care unit at Dunedin Hospital has died of Coronavirus complications.

Jocelyn Finlayson, 62, had been airlifted from Southland Hospital to Dunedin Hospital on April 4 where she was intubated and sedated for two weeks. She died on Wednesday evening.

Finlayson was one of the country's rare cases of community transmission and her family are still unsure where she picked up the virus.

She is the second person to die of Covid-19 symptoms in Southland, but the third connected to the region.

Thursday was the fifth consecutive day of no new Coronavirus cases in the Southern District Health Board area.

The number of cases in Southland and Otago is 216.

The board reported 26 active cases in Southland and Otago on Thursday, with 188 patients recovered.

Nationally, three new cases were reported Thursday, but the national total of probable and confirmed cases remains at 1451 because the cases were reported overseas.

The national death toll has risen to 16.

Director-general of health Dr Ashley Bloomfield confirmed the death on Thursday.

He said she had been in a critical condition in Dunedin Hospital and that she had an underlying health condition.

Arrangements were made to allow her family to be with her when she died, Bloomfield said.

Bloomfield addressed concerns that the family had been given false hope when the woman's condition was reported as stable by the ministry earlier in the week.

The term "stable" meant there had been no change in her condition, Bloomfield explained.

He realised that this had caused anxiety for the family, he said and added that the medical officer of health had contacted them.

"I am sorry that that's happened," Bloomfield said.

Prime Minister Jacinda Ardern said the Government was considering changing the way it reported patients' conditions.

Bloomfield also said new guidelines around visitors for Covid -19 patients would be made available under Level Three.

He said clinicians would make decisions on a case-by-case basis and if visitation was deemed appropriate, families would be provided with PPE gear.

The father of the groom whose wedding become known as the Bluff cluster was the first death linked to Southland.

An Invercargill man became the first Covid-19 death in Southland when he died in his home last week.

Finlayson is the country's youngest Covid-19 victim.

Her daughter Nicole recently told RNZ she was worried the seriousness of her mum's condition was being downplayed publicly after Ministry of Health officials reported her condition as stable.

She said the virus had completely taken over her mum's lungs.

The virus had also been spread to the five other people in her household, which included a toddler and baby.

Most of her family had recovered, but one person remained mildly symptomatic, she said.

"The authorities, nor my family, have any idea where she got it, but it seems likely it was the supermarket.

"Community transmission is happening silently," she said when her mum was admitted to hospital.

The Ministry of Health said 4 per cent of national cases represented community transmission while 2 per cent were still under investigation.

The family was asked to travel from Invercargill to Dunedin after Finlayson's condition worsened on Wednesday night.
