New Zealand Prime Minister Jacinda Ardern extended a lockdown in the country's biggest city on Friday in response to the first national coronavirus outbreak in months, sticking with a “go early, go hard” approach she said has proven effective.
Ms. Ardern said genomic testing has shown the latest outbreak is a different strain to the original outbreak in New Zealand earlier in the year, suggesting it was new to the country.
The New Zealand leader said lockdown measures in Auckland, home to about 1.7 million people, and social distancing measures across the country that were imposed on Wednesday would remain in place for another 12 days.
Her swift action followed the discovery on Tuesday of the country's first COVID-19 infections in 102 days , in a family in Auckland. Since then, officials have identified a total of 29 cases, all linked to the same cluster.
“As we have said from the start, our overall Covid-19 strategy remains elimination,” Ardern said in a televised media conference. “Together, we have got rid of Covid before. We have kept it out for 102 days, longer than any other country. We can do all of that again.”
Ms. Ardern is under pressure ahead of a upcoming general election, with the main opposition National Party accusing the government of failing to secure quarantine facilities and withholding information.
Ms. Ardern said contact tracing and genomic testing had found no links with the current outbreak to the country's border entry points or managed quarantine facilities. She said genome sequencing disproved the theory from some health experts that the virus could have been quietly moving through community since the original outbreak.
“This suggests this is not a case of the virus being dormant or of a burning ember in our community,” she said. “It appears to be new to New Zealand.”
Health Minister Chris Hipkins said earlier that genome testing suggested the new virus outbreak had originated in Britain or Australia.
Ms. Ardern cautioned that more cases were likely in the coming days but said she was confident officials would successfully identify the “perimeter” of the cluster - if not its source - allowing them to isolate cases and remove restrictions.
The earliest case authorities have identified to date is a worker at an Auckland-based cool store owned U.S.-based Americold Realty Trust, who became ill around July 31. Almost a dozen other infections have been directly linked to the facility.
The current Level 3 restrictions in Auckland requiring people to mostly remain at home, and level 2 restrictions for the rest of the country, are not as severe as the five-week level 4 shutdown she imposed earlier in the year.
“I would characterise our approach as a short but precautionary hold in an ongoing investigation that will stamp out the virus,” she said of the current measures, which will last a total of 14 days, the known incubation period for the virus.
