The Reef
Rarotonga’s reefs have stunning, healthy hard coral formations and even though Rarotonga is not a “big fish” destination, we have reef sharks, turtles, eagle rays, giant moray eels, napoleon maori wrasse, giant trevalleys, tunas, barracuas and hammerhead sharks (in season). If you are really lucky, you may even see humpback whales, tigersharks or tahitian stingrays. Apart for the bigger inhabitants, Rarotonga’s reefs have different types of moray eels, lionfish and scorpion fish, stone fish, flounders, as well as plenty of colourful fish of all the tropical reef fish families. Rarotonga is also home to some of the rarest tropical reef fishes in the world, like the Peppermint Angelfish or Narcosis Angelfish. These live very deep and the best way to see these when scuba diving Rarotonga is on a mixed gas closed circuit rebreather dive (see Technical Diving/ CCR).

Group Sizes
When scuba diving Rarotonga with us, you won’t be counting diver fins… For more enjoyable Cook Islands dive trips and more personalised scuba dive experiences, we keep our dive groups smaller than any other dive center in Rarotonga or the Cook Islands. The maximum number of scuba divers per group is 5 plus our guide, however most of the time our dive groups are smaller. This way we can cater better for the individual needs of our divers. And after all – we want to enjoy taking you out too!

Choice of Dive Sites
We dive Rarotonga’s best dives sites and we really dive all the sites around Rarotonga, we don’t just say it. We have dive sites in the north, south, east and west of Rarotonga and we decide on the day which sites we dive, this depends mainly on sea conditions but also on divers experience and preferences. If the wind blows from the north, the south is sheltered and as long as there is no big southerly swell, you will find us launching the boat in the south and diving Rarotonga ‘s south coast. If it blows from the south, we go to the north and dive Rarotonga’s north coast… This way we can dive in Rarotonga most days and it keeps the boat rides short, usually between 5 and 15 minutes. Rarotonga has around 30 dive sites and we always try to get you to different sites. Even if you are doing lots of dives with us, you won’t get bored diving the same sites all the time.

Bottom Times
We do not unnessessarily restrict your bottom time, at the same time we make sure that we stay well within dive table limits. Due to the bottom composition it is possible to do multilevel dives on most sites when scuba diving Rarotonga. This means that your dive time is usually only limited by your air supply and how fast you use it. 60 or 70 minute dives with us are not uncommon for experienced divers with low air comsumption, as long as everyone stays within table/ computer limits.

We keep our boat on the trailer, rather than having the boat moored in the harbour. This allows us to be more flexible in choosing the best dive sites for the day. By launching the boat close to the dive sites we can access all dive sites around Rarotonga within a few miuntes boat ride. There are five boat passages (gaps in the reef) on Rarotonga, of which we use three regularly: Avatiu in the north (main harbour of Rarotonga), Rutaki in the south and Avana in the east.

Our Boat and Safety
Our extremely durable and stable New Zealand made custom built 5.3m Stabi-Craft aluminium pontoon boat handles even very rough sea conditions. The dive boat is equipped with two Yamaha 50 HP outboards for extra safety and power when needed. We carry oxygen, first aid kit, lifejackets, flares, radio and mobile phone, as well as drinking water on all our Cook Islands dive trips. All our staff members are experienced and qualified skippers as well as experienced divemasters or instructors.
We use back roll entries to enter the water and as we take off the gear in the water before getting into the boat, you do not have to climb up with the gear on. Getting back into the boat is done either over the side, or for the lazy ones, the boat has a ladder on the stern.
