New Zealand authorities are investigating the possibility of its first COVID-19 case.
This investigation was carried out after more than three months, many cases originated from shipments of imported goods.
New Zealand returned to lockdown on Wednesday.
As reported by Reuters and Channel News Asia, related parties found four families infected with Corona in Auckland.
The case prompted Prime Minister Jacinda Ardern to quickly reimpose strict restrictions.
Travel restrictions across the country were also put in place.
The source of the contagion has confused health officials.
He said they believed there had been no local transmission of the virus in New Zealand for 102 days.
In addition, the family did not travel abroad.
“We are working hard to piece together the puzzle of how this family got infected,” said Health Director-General Ashley Bloomfield.
Investigations are aiming at the potential for the virus to be imported via freight.
Bloomfield said surface testing was being carried out at a refrigeration shop in Auckland.
It was precisely at the place where a man from an infected family worked.
“We firmly believe we haven’t had community transmission for a very long time,” said Bloomfield.
