One Crayfish Dive: Kaikōura Scuba for Koura, Reefs and Seals | Scuba | Water Activities

Kaikōura sits on New Zealand’s South Island where the Seaward Kaikōura Range drops into the Pacific— a place that sends deep water close to shore and stitches together mountain and ocean in a single glance. One Crayfish Dive launches from 38 West End, Kaikoura 7300; step aboard the boat Mana for two guided boat dives that explore rocky reefs, kelp gardens, and the boulder-strewn seabed that make this coast famous.

Underwater, the scene changes from broad blue to a crowded microcosm: dense seaweed forests and ribbon kelp frame fields of encrusting paua and colourful nudibranchs. Rocky terraces and reef walls shelter blue cod, wrasse, and hiding octopus; keep your light trained low to pick out mottled crayfish — koura — in crevices. Fur seals patrol these shallows with boisterous curiosity, offering one of the most immediate wildlife encounters you can have on a dive.

This is a collection-style outing with a clear rulebook. The guides will show you the best holding holes and point out legal-sized koura, but they do not harvest on your behalf. Recreational catch and size limits are respected: the limit for divers on this tour is a maximum of two crayfish per diver, with an emphasis on leaving breeders and undersized animals alone. If you don’t have your certification ID to hand the operators can look it up beforehand; Open Water certification or equivalent is required.

Beyond the grab-and-go excitement of searching for koura, the trip is a primer in Kaikōura’s unusual marine geography— a steep continental shelf, exposed rocky seabed and strong upwelling that bring nutrients and conspicuous life right to the shoreline. Expect two boat dives within an overall three-hour window; groups are intentionally small (maximum four divers) so you get personal attention and careful site selection.

Photographers and naturalists will love the macro opportunities and seal interactions; those seeking thrill should note the cold water and variable surface conditions. Safety and local stewardship are built into the adventure: operators follow regional rules and educate divers on sustainable take. Practical details: minimum age is 15, meet at the address above at tour time, and bring your certification if possible. For anyone traveling to Kaikōura for close-up subtidal exploration, One Crayfish Dive offers a bracing, responsible way to see the reefs, find koura, and share the water with seals.

Bring a reliable dive computer, sturdy gloves for handling rockwork (if you plan to gather), and thermal protection appropriate to the season; operators provide tanks and weights. The experience also connects to Māori tradition: Kaikōura — often translated as “meal of crayfish” — has long been a place where koura were gathered, and the company’s emphasis on local rules reflects both legal requirements and cultural respect.
