Ardern called the threat "unprecedented," but she was calm and reassuring. "Here's how we'll know what to do and when," she said as she laid out plans to shut down schools, most businesses and domestic travel.
Wiles at the University of Auckland says that the prime minister did something quite interesting, "which was that unlike many other countries, she never put us on a war footing."
So Ardern's speeches weren't about attacking an invisible enemy — as many world leaders would say.
Instead she called on New Zealanders to confront this crisis by protecting their fellow citizens.
"She talked over and over about us being a team of 5 million and that we all do our part to break these chains of transmission and to eliminate the virus," Wiles says. "I think that has been one of the really crucial things — everybody knowing how they had to behave and that they were behaving for the good of everybody."
Wiles heard the prime minister's calls for everyone to come together so many times that she refers to it as Ardern doing her "united thing."
New Zealand is now reopening most businesses and is even talking about complete elimination of the coronavirus from its territory.
As of late May, New Zealand had had roughly 1,500 cases and fewer than two dozen deaths from COVID-19.
