Epidemiologist happy with travel between NZ and WA

Flights between New Zealand and Western Australia can resume despite the region's latest Covid-19 scare. An MIQ security guard in Perth contracted the virus and is believed to have been infectious in the community for four days, but the risk wasn't deemed serious enough for another lockdown. However, Western Australian Premier Mark McGowan announced yesterday that Perth and Peel residents will be required to keep wearing masks indoors and outdoors, while a big AFL game at Perth Stadium has been cancelled. Flights from the region into New Zealand were cancelled on Saturday night but last night the Ministry of Health announced they could resume. Anna Thomas spoke with University of Otago epidemiologist Michael Baker.
