Businesses are buzzing over the Cook Island's bubble

Quarantine-free travel begins from May 17 - with a "flyer-beware" warning.

It means families can reconnect, commercial arrangements can resume and holidaying Kiwis can support Cook Islands tourism.

Cook Islands Chamber of Commerce chief executive Eve Hayden says it means a lot.

She says she owns two resorts and bookings started rolling in last night.

Eve Hayden says she expects other businesses to have bookings lined up, not just for May, but further out in the year.
