A blueprint to resume flights between Australia and New Zealand will be presented early next month, New Zealand Prime Minister Jacinda Ardern said.

“There is enthusiasm on both sides of the Tasman for this proposal to proceed as soon as it is safe to do so,” she told reporters on Wednesday.

Politicians from Australia and New Zealand have been discussing the possibility of opening up borders to each other, creating a travel corridor — or “travel bubble” — between the two nations.

Ardern said the Trans-Tasman Safe Border Group will present the blueprint in early June to both governments.

The blueprint is expected to include issues such as pre-flight health requirements, onboard aircraft protections, airport safety and contact tracing at arrival destinations.

It’s not clear when the flights will resume — currently both countries have closed their borders to most international visitors and all overseas arrivals are subject to a 14-day quarantine.
