Travellers will be required to take a Covid-19 test no more than 72 hours before departing and provide evidence of negative test results both on departure and arrival in New Zealand. No test will be required upon arrival in the Cook Islands.
New Zealanders will be able to travel from the main island of Rarotonga to the island of Aitutaki, with the only requirement being that travellers undergo a Rapid Antigen Test before boarding their flight to Aitutaki. A further test may be required on Aitutaki.
Cook Islands Tourism general manager Graeme West said the Cook Islands was very fortunate to have remained Covid-19 free so far.
He said the Cook Islands government had prioritised the health and wellbeing of its residents and visitors throughout the pandemic. More than 96 per cent of its eligible population are fully vaccinated.
"We were open for just three months from May to August this year until the current Delta outbreak in New Zealand meant that the border had to be closed. We are absolutely delighted that we can safely welcome fully vaccinated visitors from New Zealand back again very soon."
To assist with contact tracing in the Cook Islands, Travellers will be required to complete a Cook Islands contact form 72 hours before departing New Zealand and also use the Pacific nation's own app-based contact tracing system.
The travel corridor is exclusively open between New Zealand and the Cook Islands, and the Cook Islands maritime border will remain closed.
The Cook Islands government said full details would become available on their tourism website over the next few weeks.
