New Zealanders are waking up this morning under a level four lockdown, as the Government goes hard and early following the discovery of a community case on Auckland's North Shore.
Health officials are working around the clock to establish how a 58-year-old Devonport man became infected - with one modelling expert saying there's a chance more than 100 people could now have the virus if no clear link to the border is established.
