They are being considered a “border case” as opposed to a case of community transmission.
Prime Minister Jacinda Ardern said they were fully vaccinated and working on flights that had arrived from high-risk countries.
“This person did work in an environment where they came into contact with the planes that came from red-zones, high-risk countries,” she said.
“There is a very clear link at this stage to cases that are high risk.”
The case was picked up during routine testing on April 19. They tested negative a week earlier.
“Those protocols are working as we would intend,” she said.
The Ministry of Health said the worker was isolating.
“The usual protocol of isolating the case, interviewing them, and tracing their contacts and movements is underway,” the Ministry said in a statement.
“More information will be provided later today and this case will be included in tomorrow’s totals.”
Ardern said the case would not threaten the trans-Tasman travel bubble.
“When we opened, on both sides, we knew there would be cases on both sides of our borders,” she said.
Australian Health Minister Greg Hunt said he had “full confidence” in New Zealand’s tracing and isolating abilities.
“They’re on to this. We have full confidence in New Zealand’s system,” he told reporters in Melbourne.
“We’ve seen them deal with the inevitable outbreaks, and there will be other days when there are cases in Australia.
“We saw the outbreak recently in Queensland and NSW. And yet, we were able to deal with it. So we know how to deal with this.”
Hunt was asked how a fully vaccinated worker could still test positive for COVID-19.
He said the world was “still learning about the transmission effects of the vaccines”.
“It’s clear ... I think the CDC gave data recently on people who are fully vaccinated with Pfizer and there is a percentage, a small percentage of those, that have contracted the virus.
“What’s not known is their capacity to re-transmit.”
About 1800 Australians travelled to New Zealand on Monday without needing to quarantine.
