Tonga to Cook Islands

Hi,
Just wondering about traveling between Tonga & the Cook Islands via boat or plane - can anyone give me any tips please? We are planning on being there in October. Thanks for your time and info (in anticipation) :) Sarah

There are no scheduled boat services between countries in the South Pacific, and no direct flights between the Cooks and Tonga. You would need to travel either via Auckland or Nadi, Fiji.

There aren't direct flights from Tonga to the Cook Islands. You would need to change planes/flights in Auckland.

P.S.: AFAIK, there aren't direct flights from Nadi to the Cook Islands.
