CITC Supermarket is the go-to spot for all your grocery needs in Rarotonga. Located on the main road between Avatiu Harbour and Rarotonga Airport, this supermarket stocks everything from fresh produce to deli items, meats, liquor, baby food, toiletries, and more. With competitive prices and a large car park, it's a convenient place to stock up on essentials during your stay in the Cook Islands. Also check out Prime foods off the main road in town for another great (but not as big supermarket). Otherwise we frequented Superbrown & Wigmores Superette for small shops.
