If you’re considering exploring Kaikoura’s famed waters, a Double Boat Dive with Equipment could be a compelling choice. While I haven’t done it myself, I’ve gathered plenty of information to help you decide if this adventure fits your style. This tour promises two guided dives into the cold, clear waters of New Zealand’s South Island, with the chance to see an impressive variety of marine life—and all set against the spectacular backdrop of mountains meeting the sea.
What I really like about this experience is its focus on native marine life encounters and the breathtaking scenery. You’ll get to witness vibrant underwater gardens teeming with kelp, colorful fish, octopus, and, on lucky days, playful fur seals. The tour’s small group size—limited to 4 participants—ensures you get personalized attention, which can make a big difference in such an intimate setting. A potential drawback to keep in mind is that the waters in Kaikoura are typically cold with low visibility, so this isn’t your tropical reef-style experience, but rather a more rugged, true-to-Nature adventure.
This tour is best suited for certified divers who are comfortable in colder waters. It’s not suitable for those without certification or for non-divers. If you’re after a straightforward, well-organized way to see Kaikoura’s underwater world, and you’re prepared for the conditions, this could shape up as a memorable part of your trip.

The Boat and Dive Sites
Once onboard, you’ll set out to the chosen sites, where you’ll enjoy two dives, each lasting about an hour. The boat itself provides a stable platform for preparing gear and getting ready for the underwater adventure. Because the waters are cold and visibility is typically lower than in tropical locations, wearing proper thermal protection is essential. The equipment is provided, which is convenient for travelers who don’t want to lug their own gear.
Underwater Experience
Under the surface, you’ll find a vibrant scene of kelps and seaweeds in all sorts of colors—reds, oranges, purples, greens, and browns—draped over rocky reefs. These create a lush, textured environment that’s home to a variety of native fish species like blue cod, moki, wrasse, and butterfish. Keep your eyes peeled for octopus, and on lucky days, you might see a fur seal inspecting the bubbles and curious about the divers.
Many reviews highlight the stunning views of the mountains as a backdrop to the underwater landscape. It’s quite a sight to see the peaks meeting the sea, especially when the weather is clear. The waters are often described as cold, but that’s part of the authentic Kaikoura experience. The macro life—like nudibranchs and hidden crayfish beds—adds another layer of fascination for those who enjoy the details of marine ecology.
The Guide and Group Size
With a live tour guide speaking English and a limit of just 4 participants, the experience feels intimate and well-coordinated. The small group size is a definite plus, as it allows your guide to focus on safety and individual needs—especially helpful in challenging conditions like low visibility or colder waters.

The Practical Side: Timing, Pricing, and Suitability

The duration of 5 hours encompasses transfers, preparation, two dives, and a rest break. The actual diving time is about two hours, split into two one-hour sessions, which is decent for a guided, small-group excursion.
Pricing appears reasonable when you consider the equipment included and the expert guidance. This isn’t a cheap activity, but the value lies in the quality of the experience, especially if marine life is a priority for your visit to Kaikoura. It’s important to note that divers without certification can’t participate, and the activity depends heavily on weather conditions—so check the forecast before booking.
