New Zealand still has just one confirmed case of the disease Covid-19.
The infected person -a New Zealander aged in their 60s - travelled from Iran via Bali on an Emirates flight to New Zealand on Wednesday.
They are in a stable and improving condition in hospital and three family members are in self-isolation.
The 18 passengers who sat near them on the flight are all in self-isolation - they're mostly in Auckland, but one is in Nelson and one is in Christchurch.
Health Minister David Clark speaks to Corin Dann.
