WELLINGTON — New Zealand's Prime Minister Jacinda Ardern said on Saturday that the country's biggest city, Auckland, will go into a seven-day lockdown from early morning on Sunday, after a new local case of the coronavirus of unknown origin emerged.
Health officials, who could not immediately confirm how the person got infected, said genome sequencing of the new infection was under way.
The patient developed symptoms on Tuesday and is regarded as having been potentially infectious since Sunday, officials said. The person has visited several public venues during that period.
"Based on this, we are in the unfortunate but necessary position to protect Aucklanders again," Ardern said, announcing the lockdown.
Health authorities were trying to find out whether the new case was linked to the earlier February cluster, now at 12 infections.
The lockdown, with Level 3 restrictions, will allow people to leave home only for essential shopping and essential work, Ardern said.
Public venues will remain closed. Restrictions in the rest of the country will be tightened to Level 2 restrictions, including limits on public gatherings.
