Epidemiologist: govt most likely to extend lockdown

The government has made it compulsory to sign-in at busy locations and large gatherings to ensure the contact tracers can get on top of any new clusters quickly. It's the latest scheme to get on top of the country's outbreak, after there were 21 new community cases of Covid-19 in the country yesterday - 20 in Auckland and one in Wellington. Joining us now is University of Otago epidemiologist Michael Baker.
