There is one new case of COVID-19 at New Zealand's border, the Director-General of Health has revealed.
Tuesday's case is a woman in her 20s who arrived on July 14 from Afghanistan via Dubai. She was staying at Hamilton's Distinction Hotel.
She tested negative on day three, before returning a positive test on day 12.
Dr Ashley Bloomfield says most cases found in managed isolation are detected during the day three testing, but some don't develop the infection until later.
The woman has now been transferred to the Jet Park Hotel, the quarantine facility in Auckland.
The new case breaks a run of three successive days of no coronavirus cases.
One previously reported case has now recovered, meaning the number of active cases in New Zealand's managed isolation facilities remains at 21.
There is still no evidence of community transmission, and no one is receiving treatment for COVID-19 in hospital.
Of 1107 coronavirus tests undertaken on Monday, 872 were in the community. Dr Bloomfield says these proportions can be attributed to a lower occupancy rate in managed isolation facilities and a directive to carry out more tests in the community.
He said a survey sent out to GPs last week collected valuable information on issues doctors are facing around testing.
It revealed that about half of GPs found everyone offered a COVID-19 test was accepting, and that an increase in throat swab offers had resulted in greater uptake.
Bloomfield said the Ministry of Health will continue working with the College of GPs to work through the information gathered.
