The Australian reported this morning that the bubble was expected to begin next Monday, April 12, or the following Monday, April 19, according to the newspaper's federal government and industry sources.
Prime Minister Jacinda Ardern is set to announce when the two-way quarantine-free travel will start to Australia at 4pm today.
Australian and New Zealand residents will be able to travel between the two nations without having to quarantine from 19 April.
"Those undertaking travel on either side of the ditch will do so under the guidance of flyer beware", she said.
"Our health response now gives us the opportunity to connect with loved ones again", Ms Ardern said.
Super Rugby trans-Tasman is set to open with the Highlanders hosting the Reds in Dunedin on May. 14.
Ms Ardern called the bubble a "world-first" arrangement.
Australia provides more visitors than any other country to New Zealand, and the announcement is expected to see a flood of visitors across the Tasman.
It's expected that Air New Zealand will also be reopening their global airport lounges across Sydney, Brisbane, Perth, Melbourne, Auckland, Christchurch, and Wellington.
"For instance, 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".
Ms Ardern said there were no conversations about the possibility of a bubble with Singapore and Australia.
People will also be denied travel if they have any cold or flue symptoms.
Virgin Australia said it will not be operating flights to New Zealand during the bubble, citing "border requirements which add complexity to our business". A limited schedule for flights to and from Queenstown will remain available for booking from 18 September 2021. It will restore unrestricted, two-way travel between the two neighbors for the first time since the coronavirus pandemic forced them to close their global borders more than a year ago.
