A little preparation makes travelling around the Cook Islands easier. Rarotonga is the international gateway and has most of the services visitors need; once you head to the outer islands, plan for quieter routines and fewer facilities. Use this checklist before you fly, then confirm time-sensitive details with airlines and government sources.

Getting to the Cook Islands

International flights arrive at Rarotonga, the country’s main gateway. The current Cook Islands Tourism flight guide lists direct services from Auckland, Christchurch seasonally, Sydney, Brisbane, Honolulu and Papeete. Routes and operating days vary. Air New Zealand operates daily flights from Auckland, with a seasonal Christchurch service; check the airline’s schedule for your dates rather than assuming a route runs year-round.

If you are connecting onward to a domestic flight, allow time to clear immigration, collect your bags and check in again. Air Rarotonga recommends at least 90 minutes when connecting from an international flight to a domestic service, and 120 minutes when travelling from domestic to international. Read its connection advice before booking separate tickets.

Entry requirements

Entry rules depend on the passport you travel on. Under the current Cook Islands entry advice, New Zealand passport holders are granted a 90-day stay on arrival; holders of other international passports, including Australian passports, are granted 31 days. Visitors must show proof of onward or return travel and accommodation. The Ministry of Foreign Affairs and Immigration also lists sufficient funds, good character and an acceptable standard of health among the standard requirements. Bring your original passport, valid for at least six months beyond your departure date, and keep digital or printed copies of other confirmations easy to reach. Requirements can change, so check the official pages for your nationality and circumstances before departure.

Money and paying

The official currency is the New Zealand dollar (NZD). Cook Islands also issues distinctive local coins and notes, which are not legal tender elsewhere. The tourism currency guide says ATMs are available on Rarotonga and Aitutaki and accept Visa and Mastercard. International card withdrawals incur a local ATM fee.

Cards are accepted at many Rarotonga businesses, but carry cash for small purchases and travel beyond the main islands. Cook Islands Tourism advises taking cash to the outer islands because card payments are not readily available there. Ask your accommodation about payment before you travel. Foreign-currency exchange is available on Rarotonga; the published ATM locations are Rarotonga and Aitutaki, so do not rely on finding either service on another island.

Phones, SIMs and Wi-Fi

Check that your phone is unlocked before departure. Vodafone Cook Islands sells visitor SIMs and travel eSIMs, available online and at its Rarotonga Airport shop. The official tourism FAQ covers visitor SIM availability, and Vodafone’s eSIM information explains handset compatibility. Confirm that your handset supports eSIM before buying one. Compare the local plan with your home provider’s roaming charges.

Cook Islands Tourism lists 60 minutes of free airport Wi-Fi and more than 300 Vodafone hotspots on Rarotonga and Aitutaki. Do not assume continuous coverage elsewhere. Download maps, boarding passes, bookings and any travel documents you may need offline, and ask your host what connectivity is available at your accommodation.

Getting around Rarotonga

Rarotonga’s main road circles the island. Two yellow public buses run clockwise and anti-clockwise, stopping along the route when hailed safely. The current timetable shows hourly clockwise departures Monday to Saturday, weekday anti-clockwise departures from the half-hour, and a shorter anti-clockwise service on Saturday. Sunday has a reduced clockwise-only service and no anti-clockwise or night service. Check the timetable before setting out, especially for airport transfers or Sunday travel.

A rental car gives you more flexibility. Vehicles drive on the left. The current Cook Islands Tourism licensing guidance says eligible visitors aged 16 or over may drive for up to six months using a full, current overseas licence, for the vehicle class that licence allows; it must be in English or accompanied by a certified translation. Its licensing FAQ lists the accepted jurisdictions and says restricted licences are not accepted for ordinary visitor driving. If your country is not listed, check with Police before renting.

Do not assume a car licence covers a scooter. You need motorcycle entitlement on your home licence or a Cook Islands visitor motorcycle licence; see the same FAQ for the local application and test requirements. On Rarotonga every visitor on a motorbike or scooter must wear a helmet; the rule does not apply on the other islands. The getting-around guide sets the speed limit at 30 km/h in Avarua, at Muri Beach and in school zones, and 50 km/h everywhere else. Slow down for dogs, pedestrians and road hazards, and never ride after drinking.

Island time and domestic connections

The Cook Islands use GMT-10, according to the Cook Islands Tourism FAQ. New Zealand and the Cook Islands lie on opposite sides of the International Date Line; Air New Zealand notes its non-stop flights from New Zealand arrive on the calendar day before departure. Check arrival dates carefully when booking accommodation and transfers.

Air Rarotonga links Rarotonga with several outer islands, but not every destination has a fixed daily timetable. The Cook Islands Tourism flight guide says flights to some Pa Enua are demand-based. Check current schedules directly and allow flexibility rather than building a tight connection around a meal or activity.

Sundays and local customs

Sunday is an important day of worship on Rarotonga. Cook Islands Tourism welcomes visitors to services and advises modest clothing; its church guide gives details. The bus operator’s current timetable shows reduced Sunday service, so check it and ask your accommodation what will be open. Arrange meals and transport ahead if you need them.

Health, water and weather

Cook Islands Tourism advises visitors to boil tap water before drinking it unless their accommodation confirms the tap is filtered. You can also refill a reusable bottle at a marked filtered-water station; see the official FAQ. Pack insect repellent and take precautions against dengue. Follow local swimming signs and avoid reef passages; see the official health and safety guidance. New Zealand’s SafeTravel advice also recommends caution around strong tides and breaks.

Rarotonga offers a range of medical and dental services. Cook Islands Tourism notes limited facilities on Aitutaki, Atiu and in the Northern Group; ask your host about local access on other islands. The tourism authority recommends comprehensive travel insurance, including cover for medical evacuation. Bring personal medicines and check that your policy covers planned activities. For New Zealand travellers, SafeTravel’s Cook Islands advice notes that cyclone season runs from November to April. Check forecasts and official advice close to departure, and read our best-time-to-visit guide for the seasonal overview.
