Family members of residents who remain at Christchurch's Rosewood rest home are on edge not knowing how COVID-19 got in there.
Thirty-five residents remain inside two wings at the rest home. One of them is Mandi Lawrence's 74-year-old father Ed - he doesn't have the virus but she worries for his safety and wellbeing.
But despite no answer as to the source of the virus - Lawrence cannot speak highly enough of the rest home, the staff and the care they've given her father.
"There's no point in pointing fingers and blaming anybody in particular," she told Newshub. "The sad thing is though that yes it managed to get its way in there."
In the past three weeks 10 residents from the Linwood rest home have died due to COVID-19 - the biggest single loss of life in New Zealand from one cluster.
Eight of those who have died were amongst the 20 dementia patients transferred from the rest home to Burwood Hospital at the beginning of April.
The latest to die was a man in his 60s who was living at the rest home.
"He is the second resident from the hospital level wing of Rosewood to pass away," director of Public Health Dr Caroline McElnay told reporters on Friday.
"This man had underlying health issues and was considered to be a probable case of COVID-19."
Just how the deadly virus got into Rosewood rest home remains a mystery.
The Ministry of Health is investigating while the Canterbury District Health Board is reviewing the rest home's processes and practises.
