Australia has approved quarantine-free travel from the South Island, beginning on Tuesday.
Australia's chief medical officer Professor Paul Kelly said in a statement on Saturday from 11.59pm on Tuesday, all fully vaccinated people living in the South Island can travel to Australia if they provide a negative PCR test within 72 hours of departure.
Travellers will also have to declare they've not been in the North Island for any period of time over the last 14 days.
Air New Zealand chief customer and sales officer Leanne Geraghty says the loosening of restrictions will be welcomed by many New Zealanders.
