Essential Travel Tips
While credit cards are accepted in most resorts and larger shops, cash is king for smaller vendors, markets, and local eateries. The Cook Islands Dollar (CID) is pegged 1:1 with the New Zealand Dollar (NZD), so NZD cash is perfectly fine to use and exchange. ATMs are available on Rarotonga and Aitutaki, but it's wise to have some cash on hand, especially if you plan to explore outer islands.
Renting a scooter is the quintessential way to explore Rarotonga at your own pace, but remember they drive on the left! For a more relaxed experience, the public bus runs in both directions around the island (clockwise and anti-clockwise) and is super affordable. If you're staying in a resort area, many offer complimentary bicycles, which are great for short trips.
Embrace the 'Island Time' mentality – things move at a more relaxed pace here, so patience is key. Dress modestly when visiting villages or attending church services; cover your shoulders and knees. A friendly 'Kia Orana' (hello) goes a long way and is always appreciated by the locals.
Don't miss the local umukai feast, a traditional underground oven cooking method, often available at cultural shows or special events. For a casual bite, try the 'Ika Mata' (raw fish salad marinated in coconut cream) – it's a refreshing local delicacy. The Punanga Nui Market on Rarotonga is a must-visit for fresh produce, local crafts, and delicious street food.
Pack light, breathable clothing like cotton and linen, as it's tropical year-round. Don't forget reef-safe sunscreen, a wide-brimmed hat, and insect repellent, especially for evenings. A reusable water bottle is also a good idea, as many places offer filtered water refills to reduce plastic waste.
The Cook Islands are incredibly safe, but always be aware of your surroundings, especially at night. Be cautious when swimming in the ocean; always swim between the flags at patrolled beaches and be mindful of currents. Respect marine life and avoid touching coral, as it's a delicate ecosystem.

Frequently Asked Questions
When's the absolute best time to visit the Cook Islands if I want perfect weather and fewer crowds?
Honestly, the sweet spot for me is the shoulder season, typically May through October. You'll get that glorious dry season weather with plenty of sunshine and lower humidity, but you'll also miss the peak holiday crowds and prices of July and August. It's that perfect balance of ideal conditions and a more relaxed vibe.
I've heard about the 'island time' culture. How should I best prepare myself for it?
Embrace it! 'Island time' isn't just a saying; it's a way of life. Don't expect things to run on a strict schedule – whether it's a bus, a meal, or a tour. My best advice is to build flexibility into your plans, leave your watch behind, and go with the flow. The locals are incredibly friendly, so a relaxed attitude will make your interactions so much more enjoyable.
Beyond Rarotonga and Aitutaki, are there any other islands worth exploring for a truly off-the-beaten-path experience?
Absolutely! If you're looking for raw, untouched beauty, consider venturing to the Southern Group islands like Atiu or Mauke. Atiu, in particular, is fascinating with its ancient caves, unique birdlife, and a strong connection to traditional culture – you can even take a tour with a local elder. It's a world away from the more developed islands and offers a glimpse into a slower, more authentic Cook Islands life.
What's the best way to get around Rarotonga, and are there any local transport tips I should know?
The most iconic way to see Rarotonga is by hopping on the local bus – it runs clockwise and anti-clockwise around the island, and it's incredibly affordable and a great way to people-watch. For more freedom, renting a scooter is very popular and gives you easy access to hidden beaches and viewpoints. Just remember to drive on the left and be aware of the occasional stray chicken or dog crossing the road!
Is it easy to get local currency, and should I carry cash or rely on cards?
The local currency is the New Zealand Dollar (NZD), which is widely accepted. While credit cards are taken at most hotels, restaurants, and larger shops, it's always a good idea to have some cash on hand, especially for smaller markets, local craft stalls, or when visiting the outer islands. ATMs are available in Avarua on Rarotonga, but they can sometimes run low on cash, so don't rely on them solely.
What's a common cultural faux pas I should avoid as a visitor?
Respecting local customs is key. While the Cook Islanders are very welcoming, it's polite to dress modestly when venturing away from the beach or resort areas – cover your shoulders and knees when visiting villages or churches. Also, always ask permission before taking photos of people, especially elders.
