The Ministry of Heath has confirmed it is investigating two more possible cases of Covid-19 related to Auckland's Pullman Hotel. The returnees completed their managed isolation in the same facility as a 56-year-old woman who also tested positive for Covid-19 after leaving the hotel. The Ministry says the two former returnees in question both returned a positive test for Covid-19, however it is yet to be confirmed if they are recent or historic infections. Further urgent testing is being carried out this evening and both individuals are currently self-isolating at home. The Ministry of Health has declined requests for an interview, but microbiologist Siouxie Wiles joins Lisa Owen to discuss the issue.
