Spot listing for Pillar Rock with depth and fish-life summary.
Pillar Rock
Kelp-covered reef and boulder dive in the Bay of Islands.
About Pillar Rock
Pillar Rock is a Bay of Islands reef dive with kelp-lined structure, boulders, and broken reef that starts shallow and falls away into deeper water on the outer edges. It is usually dived as an easy-to-read open-water site rather than a technical feature dive. Expect schooling fish around the reef, occasional crayfish tucked into cracks, and the chance of larger visitors passing through when blue-water conditions clean up.

Safety Notes
Treat Pillar Rock as an open-water boat dive with changing surface conditions, deeper edges beyond the shallow reef, and standard blue-water ascent discipline around the boat.
Access Restrictions
Usually dived by charter boat from the Bay of Islands, with site choice and timing shaped by daily weather, sea state, and skipper assessment.
Legal Notes
Pillar Rock sits within Te Pēwhairangi (Bay of Islands) Marine Mammal Sanctuary, so divers must stay out of the water within 300 m of marine mammals and vessels must follow sanctuary approach and speed rules.

Scuba
A large-area reef dive with depths ranging from shallow to 30 m.
Freedive
Pillar Rock can suit boat-based freedive sessions on calm days because the upper reef starts shallow and fish life often holds above the deeper edge, but support-boat awareness remains important.
Snorkel
Not usually treated as a primary snorkel stop. It is better suited to divers or skilled boat-supported snorkelers on calm days with clear surface conditions.
