Anyone who has recently arrived from China is being urged to immediately isolate themself and to register to get welfare checks via the phone.
The Ministry of Health has created a dedicated phone number via the existing Healthline service for any calls related to the deadly coronavirus.
Those who need to self-isolate can call 0800 358 5453, or (09) 358 5453 for those ringing from overseas.
The ministry's director-general, Dr Ashley Bloomfield, said this morning there were about 1000 people arriving on flights from China every day, so there could be "several thousand" people in self-isolation around New Zealand currently.
