The Pinnacles (D'Urville Island) – Marlborough Sounds & Nelson/Tasman
Site Overview
The Pinnacles off D'Urville Island at the outer reaches of the Marlborough Sounds offer dramatic offshore pinnacle diving with massive schools of blue maomao, kingfish, and seasonal bronze whaler shark encounters in pristine clear water. The rocky pinnacles rise from deep water at the boundary between the Marlborough Sounds and the open ocean, creating concentrated marine habitats where nutrient-rich currents support extraordinary biodiversity. The underwater topography consists of sheer rocky pinnacles rising from depths beyond recreational limits, their walls covered in dense soft coral gardens and gorgonian fans. Massive schools of blue maomao create shimmering walls of blue on the pinnacle slopes, while kingfish patrol the reef edge hunting smaller fish. Pink maomao join the aggregations at deeper depths, adding purple hues to the colourful fish schools. New Zealand fur seals regularly visit the pinnacles, their playful curiosity creating memorable underwater encounters as they interact with divers. Bronze whaler sharks make seasonal appearances during the summer months, cruising the blue water beyond the pinnacle edges. The remote offshore location ensures crystal-clear water with visibility often exceeding 25 metres, making the Pinnacles a premier wide-angle photography destination. The combination of dramatic pinnacles, massive fish schools, seal encounters, and potential shark sightings makes the D'Urville Island Pinnacles the ultimate offshore diving experience in the Marlborough Sounds region.
Dive Briefing
"The dive begins at the tallest pinnacle at approximately 8 metres, where the rocky reef is covered in colourful soft corals and demoiselles. Descend along the pinnacle face following the current, which typically flows around the pinnacle group. Schools of blue maomao appear within the first few minutes, growing larger and more concentrated with depth. Kingfish patrol the reef edge, while pink maomao join the aggregations at 15 to 20 metres. At 25 to 30 metres, the soft coral coverage reaches maximum density and the fish aggregations are most impressive. Fur seals may approach the pinnacle, interacting with divers in playful encounters. Bronze whaler sharks may patrol the blue water beyond the pinnacle edge during summer months. The return follows the shallower pinnacle crest at 10 to 15 metres. The safety stop is conducted on the pinnacle crest. Watch for fur seals approaching the pinnacle from the blue water, their playful curiosity creating memorable underwater encounters. The deeper pinnacle slopes at 25 to 30 metres support the most impressive fish aggregations and soft coral coverage in the offshore environment."
