FROM THE REST OF THE WORLD
Travel to and from the Islands from anywhere other than New Zealand is not allowed at the moment. And because there are strict controls on who can enter New Zealand, I'm afraid a visit isn't possible....but you can still plan!
The best advice for those wanting to visit the islands from anywhere else in the world once travel restrictions are lifted is to contact your travel agent or favourite airline. If you're planning a round the world trip with the Cook Islands on your itinerary, one option is the Star Alliance which includes Air New Zealand, Singapore Airlines, Air Canada, Lufthansa and Asiana Airlines. RTW tickets offer substantial savings over what you would pay if you booked each flight separately.
