New Zealand reported no new coronavirus cases Monday, marking a significant moment that indicated the country’s bold strategy of trying to eliminate the virus was working.

It was the first time since the outbreak took hold in mid-March that the country reported zero new cases. Director-General of Health Ashley Bloomfield said the figures were clearly encouraging, but the result represented a moment in time and it won’t be until later this week that officials will know if new cases are continuing to pop up in the community.

New Zealand closed its borders and imposed a strict monthlong lockdown after the outbreak began. The lockdown rules were eased a little last week to help reopen the economy, but many restrictions remain in place.
