(CNN)New Zealand's Prime Minister Jacinda Ardern has announced a nationwide lockdown after the country confirmed one coronavirus case -- the first locally transmitted Covid-19 case in the community since February.
Ardern told a press conference Tuesday authorities were assuming it was the contagious Delta variant, although genome sequencing is still underway.
An unvaccinated 58-year-old man in the country's largest city Auckland tested positive for the virus. The man had traveled to other parts of the country, and had obvious link to the border, Director General of Health Ashley Bloomfield said Tuesday.
New Zealand will be under the strictest level lockdown level for the next three days starting from 11:59 p.m. Tuesday, local time, Ardern said. Under level four lockdown, everyone must stay home and businesses are closed aside for essential services such as supermarkets and pharmacies.
New Zealand was last under its most serious lockdown level a year ago, Ardern said.
Auckland and the Coromandel Peninsula -- an area of the country's North Island where the patient traveled -- are likely to be under a level four lockdown for a week.
"We are one of the last countries in the world to have the Delta variant in our community," Ardern said. "We're in the position to learn from experience overseas, and what actions work, and what actions don't work."
"Delta has been called a gamechanger -- and it is. It means we need to again go hard and early to stop the spread. We have seen what can happen elsewhere if we fail to get on top of it. We only get one chance."
New Zealand has been praised for its handling of the virus, which saw it close borders to almost all foreign nationals early, and impose strict state-run quarantines on incoming travelers.

Quite the contrast to the US, where we are barreling towards 200k daily cases and 100k hospitalizations, with ICU's across the South filled up and refrigerated trucks ready to carry all the bodies, but instead of a lockdown, or even mask mandates in all states, places like Florida and Texas are taking preventative measures...to ban mask mandates in schools.
