Arrive in the Cook Islands through Rarotonga International Airport (RAR), then take an Air Rarotonga domestic flight to Aitutaki (AIT). The airline and Cook Islands Tourism describe a roughly 40-50 minute leg; timetables and weather reliability need checking directly at the official schedule page. A same-day Aitutaki Day Tour bundles round-trip flights with a lagoon cruise but does not create a sensible scuba itinerary because flying immediately after diving violates preflight surface interval recommendations. Overnight stays in Aitutaki support better dive flexibility. No regular interisland passenger ferry or overnight dive-liveaboard route was independently verified for this specific visitor scope. Weather or flight disruption may necessitate an extra buffer night.

Aitutaki's domestic airport receives Air Rarotonga flights from Rarotonga. The airport authority says it operates during regular domestic flight hours. Confirm the operating flight and accommodation pickup directly.

Aitutaki is a small island with localized accommodation and tour pickups. Arrange airport and wharf transport with the resort or operator; the famous clockwise/counterclockwise bus system is on Rarotonga, not proof of Aitutaki service. Bicycles, rental cars and scooters can support exploration. Cook Islands vehicles travel on the left. According to official transport guidance, full overseas licenses apply only to vehicle classes already endorsed, and scooters may require a motorcycle class or a visitor licensing process. Preconfirm current permit location, helmets and rental insurance. The accessible lagoon motus are reached through organized boats.

As published in the 26 October 2026 Cook Islands entry advisory, New Zealand and Australian passport holders normally receive up to 90 days on arrival, and other international passport holders up to 31 days, subject to admissibility. Passports should be valid for at least 6 months beyond departure; carry confirmed onward/return travel, accommodation and adequate funds. Extensions require separate government approval and fees; use the MFAI immigration rules for the passport-specific procedure. Travel via New Zealand may require its own transit/entry authorization. Aitutaki is domestic after clearing Cook Islands arrival formalities on Rarotonga.

Use Air Rarotonga baggage guidance before flying with fins, dive luggage or batteries. The bundled Aitutaki Day Tour includes only cabin baggage, while regular fare classes can include checked baggage depending on ticket. Confirm actual scuba rental availability, tank supply, weights, exposure suits and oxygen kit with Dive Aitutaki after the reported 2026 scuba pause. Teking and Bishop's say standard snorkel equipment is included, but personal fit matters; carrying your own mask is reasonable. There is no basis to assume nitrox fills, technical gases, compressor servicing, dive-gear repair or current equipment-course availability on the island. No scuba, snorkeling or freediving expedition should depend on locally available replacement parts without operator confirmation.

NZD is the official money. Cook Islands notes and coins are issued locally and may not be usable overseas. Tours generally quote NZD. Cook Islands Tourism travel tips advises keeping local cash for outer-island shopping and smaller providers, even when card facilities are available.

Cook Islands Tourism confirms ATMs on Aitutaki, including outside the airport arrival hall, accepting Visa and Mastercard, often with foreign-card withdrawal fees. Foreign-currency exchange is described as available on Rarotonga rather than Aitutaki, so carry NZD and keep an alternative payment method.

Type I sockets are used as in New Zealand/Australia. Carry an adapter and check that US electronics support 240V input; a plug adapter does not transform voltage.

Communications

Vodafone Cook Islands provides visitor SIM/eSIM options and Wi-Fi hotspots on Aitutaki according to tourism travel tips. Download offline maps and contacts before flying because isolated beaches and motus may have weaker service and bookings can be disrupted. Ask the operator whether its boat carries radio or satellite communications rather than assuming mobile coverage.

Language

English and Cook Islands Maori are used locally. Basic greetings such as Kia Orana are welcomed. Ask for a briefing you understand and follow community etiquette and locally posted access signs.

Insurance

Select an insurer explicitly covering recreational scuba to the depth you will dive, snorkeling, freediving training if relevant, boating and medical evacuation. Australia's travel advisory notes costly evacuation, limited outer-island medical facilities and no local recompression chamber. Check whether repatriation from Aitutaki via Rarotonga to a working chamber overseas is covered, and whether animal interactions or scooter rentals are excluded. The government's 2026 patient referral policy does not finance tourist evacuation. Carry insurance and emergency numbers offline.

Packing list

Pack lightweight modest clothing, a sun shirt, broad-brim hat, high-SPF reef-conscious sunscreen, reusable water bottle, mask that fits, drybag, suitable boat footwear and a light rain jacket for showers. Bring any personal medication and motion-sickness supplies, certification card/computer if diving, and a Type I plug adapter. Ask in advance about equipment rental; Air Rarotonga has ticket-dependent baggage limits. Do not transport scuba cylinders or restricted equipment without airline approval.
