Boat dive on Great Mercury Island's southeast reef with kelp-covered rock, sand patches, and a calm-day window that matters more than depth.
About SOUTH EAST CORNER
South East Corner is a boat dive on the Great Mercury Island side of the Coromandel, where a long kelpy reef rolls through a shallow middle section and then opens into an exposed coastal run. When the sea is calm, it can be a rewarding temperate-water dive with fish, crayfish, and the chance of rays or even orcas, but the site is very sensitive to wind and swell and needs a good weather window to work well.

Community notes to help plan your visit.
Scuba Diving
Best as a calm-day guided boat dive, with the reef and exposure doing most of the work.
Freediving
Shallow enough for experienced freedivers only when the sea is calm, but swell exposure is the main limiter.
Snorkeling
Only realistic in very calm weather because the reef exposure is the main constraint.
