How did New Zealand stamp out coronavirus?



New Zealand lifted most of its coronavirus restrictions on Monday as the country reported no active cases.

Prime minister Jacinda Ardern said she “did a little dance” when she was told the country was effectively coronavirus-free, meaning all of New Zealand was to be moved to level 1, the lowest of a four-tier alert system, with the goal of completely ending transmission of COVID-19 within its borders.

Under the new rules, which come into effect at midnight local time on Monday, people no longer need to social distance from each other and there are no limits to public gatherings but, crucially, borders remain closed to foreign travellers.

New Zealanders arriving from abroad will go through a 14-day period of isolation.

The Pacific island nation is among only a handful of countries that have emerged from the pandemic, as big economies like the US, Britain, India and Brazil continue to grapple with the spreading virus.

But how did it manage to completely clear the country of coronavirus?


New Zealand is a remote nation with a population of just 5 million and its external borders are easily sealed.

Its isolated location in the South Pacific gave it vital time to see how outbreaks spread in other countries, and Ardern acted decisively by imposing a strict lockdown early in the outbreak.

Also, notably, biosecurity in New Zealand guards against threats to agriculture and biodiversity, with strict border control measures being taken to prevent unwanted organisms from entering the country.

Decisive strategy

Ardern has won plaudits for acting quickly in the face of the pandemic, even as other western countries appeared remarkably slow to introduce lockdown restrictions.

“We’re going hard and we’re going early,” Ardern told the public in mid-March.

“We only have 102 cases, but so did Italy once.”

Ardern imposed a strict lockdown early in New Zealand’s outbreak, giving the government time to set out its own strategy, which heavily focused on border control and elimination.

She announced that New Zealand was going to rapidly escalate levels of physical distancing and travel restrictions on 23 March, reaching the level of a full national lockdown days later.

By effectively putting the country into mass home quarantine for a month, many chains of COVID-19 transmission were extinguished.


On 23 March, a month after the country recorded Car Accident Attorney in Milwaukee its first case, New Zealand committed to an elimination strategy.

The approach focused on delaying the arrival of the virus, followed by a range of measures to flatten the curve of cases and deaths.

New Zealand had been taking a similar approach to Australia by following their pandemic plans but diverged when it embraced the elimination strategy.

Controls were increased after 15 March to require 14-day periods of self-isolation for all arrivals.

Case isolation, contact tracing and quarantine to stamp out cases were also being used.

Michael Baker, professor at the University of Otago’s department of public health in Wellington, who has been advising the New Zealand government on its response, said implementing a full lockdown – including the closure of schools and non-essential workplaces, a ban on social gatherings, and severe travel restrictions – enabled the country to consider elimination.

Baker told medical journal The Lancet the full lockdown allowed the country to get key systems up and running to manage borders effectively and do contact tracing, testing and surveillance.
