Why dive here
With 35+ marine species recorded in the area - including humpback whales, seahorses and sperm whales - Double Cove Marine Reserve offers some of Kaikōura's richest reef diving. Water ranges 10-17°C, warmest January, February, March.
Double Cove is one of those places you remember, even if you’re not tracking hundreds of dives. We love it for how approachable it is, perfect for getting back in the water after a break or introducing someone new to diving. The maximum depth sits around 14m, and while the average visibility of 6m might not sound like much, it often feels better in the sheltered water, especially on a sunny day when light penetrates the kelp forest. What makes it special are the incredibly bold blue cod. They’ll swim right up to your mask, inspecting you with an almost comical curiosity. You'll glide over rocks covered in purple worms and find eleven-armed seastars clinging to the kelp. Look closely for tiny common triplefins flitting around the holdfasts. Access is easy, either by boat or a small jetty, which means less fuss and more time looking for cowfish amongst the swaying Neptune's necklace. It’s a great spot for an easy, relaxing dive where the local residents are genuinely happy to see you.
