Wellington, New Zealand CNN  — 

New Zealand has managed to do something that many countries wish they could achieve: for four straight days, it has reported a decline in new coronavirus cases.

On Thursday, the country reported 29 new confirmed and probable cases, bringing New Zealand’s total to 1,239 – including only one death. Of those cases, only 14 are in hospital – and 317 have recovered.

New Zealand, a small island country with a population of just under 5 million, is halfway through a month-long lockdown aimed at not only containing the virus, but eliminating it.

And so far, the approach appears to be successful.

“We are turning a corner,” Prime Minister Jacinda Ardern said in a speech Thursday. “And your commitment means our plan is working.”

For other countries, those positive signs might be a reason to lift restrictions. Denmark, which has at least 5,597 cases and 218 deaths, announced it will begin to lift its lockdown next week if cases remain stable.

Instead, Ardern said Thursday she was tightening border restrictions, meaning all those who arrive in the country will be required to spend two weeks quarantined in an approved facility, rather than self-isolating at home. The rule only applies to New Zealanders – foreign nationals have been banned from entering the country since March 20.

“At the halfway mark, I have no hesitation in saying that what New Zealanders have done over the last two weeks is huge,” Ardern said at a press conference Thursday that many Kiwis listened to live. “You made the decision that together, we could protect one other. And you have. You have saved lives.”

“But as I’ve said, this is going to be a marathon.”

A house fence has been chalked up with messages relating to the Covid-19 lockdown on April 3, 2020 in Auckland, New Zealand.

New Zealand’s head-start

In the fight against coronavirus, New Zealand had two key advantages: geography and time.

On February 28, New Zealand confirmed its first case of coronavirus, well over a month after the United States confirmed its first case. And on March 29, the country confirmed its first – and so far, only – death.

“I think we had a little bit more time to think about it, and we could learn from the experience of China,” said Professor Michael Baker, from Otago University’s Public Health Department, who helped advise the government on its response.

New Zealand also had the advantage of being an island far from most other countries, with fewer flights than many other places, said Auckland University microbiologist Siouxsie Wiles.

That’s something Ardern has pointed out. On Thursday, she noted that being an island was a “distinct advantage in our ability to eliminate the virus.”
