The idea of the travel bubble has been in the news for almost 12 months but has previously been scuttled due to outbreaks.
But she added: "People will need to plan for the possibility of travel being disrupted if there is an outbreak". It's the first taste of restriction-free global travel we have seen since the COVID-19 pandemic began. Although do note that the Queenstown to Sydney service is set to begin one day later, on April 20.
Airlines and airports stressed yesterday that they were ready to go, and Air NZ is planning to operate quarantine-free flights from April 12 from Auckland to Sydney, Melbourne and Brisbane. It's still unclear whether Qantas, American Express, and Plaza Premium will be doing the same, although it's reasonable to assume that similar reopening announcements will follow shortly.
Australians heading to New Zealand will be kept separate from other global arrives who are still required to go into mandatory hotel quarantine for 14 days. Australians will soon no longer be required to quarantine on arrival. That policy has now been scrapped.
Australians will be able to travel to New Zealand without having to quarantine from 11:59 pm on Sunday April 18, Ms Ardern said Tuesday afternoon.
New Zealand and Australia are among the top performers in the global battle against the virus - New Zealand has consistently topped Bloomberg's Covid resilience ranking and Australia now lies third.
NZ first agreed the bubble in May after Ms Ardern attended National Cabinet, with Australian counterpart Scott Morrison and state and territory leaders.
"If we saw multiple cases of unknown origin, we would likely suspend flights for a set period of time".
