The New Zealand Customs Service says the Government has announced temporary restrictions on travellers arriving in New Zealand from mainland China or Iran as a precautionary measure to protect against the spread of COVID-19.

The restrictions prevent foreign nationals travelling from or transiting through mainland China or Iran from entering New Zealand.

People who are exempt from the temporary restrictions are:

• New Zealand citizens (including those from the three Countries of the Realm: Tokelau, Niue and the Cook Islands), permanent residents and their immediate family
• Australian citizens and permanent residents whose primary place of established residence is New Zealand
• air crews who have been using appropriate personal protective equipment (PPE).

People exempt from the temporary restrictions should self-isolate for 14 days after their return if they have been in mainland China or Iran, or exposed to a confirmed case of COVID-19.

People who have been in Italy or the Republic of Korea (excluding airport transfer) should self-isolate for 14 days after their return.

"Self-isolation means you should avoid situations that could facilitate the transmission of the virus such as social gatherings and events where you come into contact with others; in particular child care/pre-school centres, primary and secondary schools (including staff and students), aged care, health care facilities, prisons, and public gatherings," Customs says.
