An essential worker in Whangārei has returned a “weak positive” Covid-19 test on Wednesday.
Northland DHB confirmed the person was tested on Monday as part of surveillance testing, and was asymptomatic when tested.
The DHB said the situation is “under investigation”.
“It is only a matter of time before Northland has a positive Covid-19 case, and it is imperative that everyone who is eligible is vaccinated against Covid-19 as soon as possible,” DHB chief executive Dr Nick Chamberlain said.
"Even if it doesn't turn out to be positive, this would be the second near-miss in the last week after a case last week in the Far North that turned out not to be infectious while up here.
“We’ve seen in nearly every other country in the world what happens when the virus rolls through a community of unvaccinated people, and it’s grim.”
Covid-19 Response Minister Chris Hipkins said the result was a "very weak" positive.
“The test result is not yet clear as to whether it not it is definitely a case," he said.
He said the person was usually based in Auckland, but was in Whangārei when the test was taken.
Hipkins said the person was now back in Auckland.
A repeat test for the worker is being organised.
