New Zealand, a country of about 4.8 million, has now gone 100 days without a single locally transmitted case of COVID-19, according to news reports. 

The last COVID-19 case acquired locally from an unknown source was reported on May 1, BBC News reported, around the time that lockdown measures began to ease.
