Meanwhile, health authorities here are urging several thousand New Zealanders who've recently returned from China to register with a new helpline if they're in self-imposed quarantine.
The Ministry of Health's latest advice says anyone who travels to New Zealand after Monday - February 3 - should isolate themselves for two weeks if they were in mainland China - or were exposed to someone with the new coronavirus.
Anyone who travelled from Hubei or Wuhan city before February 3 should also isolate themselves, meaning they should avoid close contact with others, workplaces, schools, and restaurants.
The director-general of health Dr Ashley Bloomfield told RNZ reporter Chen Liu registration means people can seek advice and authorities can check on their welfare.
