As of Monday, the country had reported 1,219 confirmed cases, including just 21 active infections, all in managed isolation facilities. No cases had emerged via community transmission in 100 days, authorities announced Sunday, with all new infections coming from abroad.
In total, the island nation of 5 million people has reported 22 coronavirus deaths.
While other countries -- including Pacific neighbor Australia and the United States -- continue to battle outbreaks, New Zealand has been held up as an example of how to fight Covid-19. One key reason is that although the country appears to have the coronavirus under control, authorities are still testing thousands of people a day.
"We have seen overseas how quickly the virus can reemerge and spread in places where it was previously under control," Director-General of Health Dr. Ashley Bloomfield said Sunday.
"We need to be prepared to quickly stamp out any future cases in New Zealand. Don't let the team down -- none of us can afford to do that."
