Air New Zealand has put a further hold on flights to Australia

It's because the Australian Government's extended its cap on international arrivals until October 24.

It means only 25 passengers are allowed on each flight into Brisbane and about 40 on each one into Sydney.

International arrivals into Melbourne are not permitted at all.

The airline's Chief Commercial and Customer Officer, Cam Wallace, says when it comes to flights to Sydney, there's availability from early next month.

Although there's a hold on new bookings to Brisbane, he says flights could become available if customers change bookings or no longer wish to travel.
