A staunch claim home isolation isn't broken.

The Ministry of Health is reviewing the model after a second person died of Covid-19 while isolating at home.

The person discharged themselves from hospital on Wednesday and was found dead at their address this morning.

Two days ago another person was found dead at their South Auckland apartment.

ProCare Chief Executive Bindi Norwell told Heather du Plessis-Allan says the system is hedged with safeguards.

She says health workers are doing all they can to ensure the system is working well.
