Essential Travel Tips
Use New Zealand dollars (NZD) – it's widely accepted and often offers better exchange rates than using other currencies. Many places will accept credit cards, but it's always wise to carry some NZD for smaller purchases, especially in more remote areas like Aitutaki.
Island hopping is best done via Air Rarotonga or smaller inter-island flights. Book in advance, especially during peak season, to secure the best prices and avoid disappointment. Ferries are an option between some islands, but they can be slow and weather-dependent.
Learn a few basic Cook Islands Māori phrases – locals really appreciate the effort! A simple 'Kia Orana' (hello) and 'Maururu' (thank you) go a long way in showing respect and creating a more welcoming experience.
Embrace the fresh seafood! The Cook Islands have some of the best in the world. Many restaurants offer 'catch of the day' options, and the local markets are great places to find fresh fish and other local produce at affordable prices.
Pack light clothing made from natural fabrics like cotton and linen. The weather is generally warm and humid, and light clothing will keep you comfortable. Don't forget reef-safe sunscreen and a hat for sun protection, especially if you plan on spending time outdoors.
Tap water is generally safe to drink on Rarotonga and Aitutaki, but it's always a good idea to check with your accommodation. Mosquitoes can be prevalent, so pack insect repellent, especially if you're visiting during the wet season. Be mindful of the sun and stay hydrated.

Frequently Asked Questions
What is the best time to visit the Cook Islands for ideal weather and fewer crowds?
The Cook Islands enjoy a tropical climate year-round, but the shoulder seasons (April-May and September-October) offer a sweet spot. You'll find pleasant temperatures, fewer crowds than the peak summer months (June-August), and often lower airfares. Plus, the water is still warm and perfect for swimming and snorkeling.
What are some local customs or etiquette tips I should be aware of when visiting?
The Cook Islands people are incredibly welcoming, but showing respect for their culture goes a long way. It's customary to greet people with a 'kia orana' (hello), and a small gift of appreciation for any hospitality received is always appreciated. Also, be mindful of local traditions and customs, and dress modestly when visiting churches or marae (traditional meeting houses).
How easy is it to get around the different islands in the Cook Islands?
Inter-island travel is fairly straightforward. Domestic flights are efficient for longer distances, particularly between Rarotonga and Aitutaki. Ferries are a more scenic but slower option for traveling between closer islands. Rarotonga itself is easily explored by bus or rental scooter, offering a great way to experience the island at your own pace.
Are there any hidden gems or lesser-known spots that you would recommend?
Beyond the iconic Aitutaki lagoon, consider exploring the less-visited islands like Manihiki or Pukapuka for a truly off-the-beaten-path experience. These islands offer pristine beaches, unique local cultures, and opportunities for incredible diving and fishing. You'll need to plan ahead, but the rewards are immense.
What's the best way to handle money and currency in the Cook Islands?
The Cook Islands dollar (NZD) is the official currency, but many places also accept credit cards. It's always a good idea to have some local currency on hand, especially for smaller purchases or in more remote areas. ATMs are available on Rarotonga and Aitutaki, but less so on the outer islands, so plan accordingly.
