New data from Skyscanner has revealed the cheapest months to visit New Zealand, with savings of up to 40 per cent on fares for those with flexible travel dates.
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.
"If a case is found that is quite clearly linked to a border worker in a quarantine facility and is well contained, you'll likely see travel continue in the same way as you could see life continue if that happened here in Australia", said the New Zealand PM.
This marks the first time Australians will be allowed to travel outside the country quarantine-free and without the need for exemptions.
Qantas is now updating its timetable to ramp up travel between Sydney and Auckland and will offer Frequent Flyers uncapped Classic Flight Reward seats for the first three days of travel when the borders open.
Those coming from Australia will be on planes exclusively for Australians, Ms Ardern said.
'If there is a hot spot in one of the states of Australia we may just act in the same way that another state would, with just limitation of people to come in and out of our borders until that issue is resolved'. This will be made possible because up to 1,300 rooms will be freed up with the creation of the bubble. "Just prepare that there may be disruptions".
"With the strategy that we have had, it has meant that the vaccine for us hasn't been a question of life and death in the same way it has in other parts of the world".
Ms Ardern quickly shut down the invitation to join in.
Ardern has also outlined situations in which the travel bubble would remain in-tact, as well as situations in which it would be paused.
"Those countries that are working very hard to roll out those vaccines, it's in order to get the freedoms we already have".
Australian and New Zealand sides are currently playing in their second domestic Super Rugby seasons, but can now plan for the trans-Tasman competition which is due to kick off on the 14th of May. This will include vigilant contact tracing, and "green zones" separating travellers from Australia and New Zealand, and travellers from other destinations not within the bubble.
Ms Ardern said they were still awaiting evidence that demonstrated people travelling from high-risk countries would not pose a threat, before establishing a vaccine passport system.
The Australian Airports Association also welcomed the bubble, describing it as a much-needed boost to the tourism and aviation industries.
Trade between the two countries is worth NZ$25.6 billion, according to New Zealand data, making Australia New Zealand's biggest trading partner.
She warned Australians would "need to plan for the possibility of travel being disrupted if there is an outbreak".
"But nothing like the human-to-human contact for us that is so important".
