Australian and New Zealand residents will be able to travel between the two nations without having to quarantine from 19 April.
New Zealand Prime Minister Jacinda Ardern announced the move today.
Since October, New Zealand travellers have been allowed to enter most Australian states without quarantine, though this had not been reciprocated.
Both nations have since contained Covid outbreaks and kept infection rates near zero.
The countries shut their borders in March last year and brought in compulsory quarantine for returning nationals.
When outbreaks have emerged, both Australia and New Zealand have instated snap lockdowns to halt the virus from spreading.
Ms Ardern praised such aggressive responses as key to opening the travel bubble.
Australian Prime Minister Scott Morrison welcomed Ms Ardern’s decision, while noting that his country’s border had been open to New Zealanders for close to six months already.
Australia has recorded 909 deaths since the pandemic began, while New Zealand has reported 25.
