Around 3600 people in New Zealand have completed their self-imposed isolation period for the coronavirus and will be able to return to their "normal lives".
The Ministry of Health's director-general of health Dr Ashley Bloomfield says Healthline's register has been a successful way to track people's health since they've arrived back in New Zealand - but they're still chasing people who haven't registered.
"The register is not there to police people. As far as I'm aware, we're the only country that is doing this and it's so that we can keep track of people's wellbeing and welfare."
He says the register also helps with the Health Ministry's overall public health response.
The dedicated COVID-19 Healthline number is 0800 358 5453.
From February 3 to midnight on February 18, 8260 people have arrived in New Zealand either directly from, or travelling through China.
There are still no confirmed or suspected cases of COVID-19 in New Zealand.
