Prime Minister Jacinda Ardern has confirmed a suspected case of Covid-19 coronavirus has tested positive.
The person was in their sixties, and was a citizen of New Zealand who had recently travelled from Iran via Bali, she says.
They were in an improving condition in isolation in Auckland hospital after arriving on Thursday night.
Director-General of Health Ashley Bloomfield says the person arrived this week from Iran, where the virus had been rapidly spreading.
He earlier said five people were being tested for the virus in New Zealand, but only this person fit the definition of a suspected case.
He says 130 tests for Covid-19 had been done this month, all of them negative except this one.
In a statement, the Ministry of Health say they received the test results about 4.15pm today.
The ministry say the patient was being treated in Auckland City Hospital in an improving condition in isolation.
The chances of community outbreak remained low, the ministry says, and public risk from the new infection was being well managed because of the public messaging, awareness of Covid-19 and public health response to managing cases and contacts.
