Dive-site story
South Sunk is a submerged reef formation lying offshore in the waters of Mercury Bay near the Coromandel coast. The structure rises abruptly from the seafloor, featuring steep rock faces, broken gullies, and boulder terrain draped in Ecklonia kelp. Pelagic species frequently sweep past the exposed high points, while the crevices shelter resident reef fauna.
Steep rocky walls and submerged pinnacle terrain encrusted with sponges and anemones
Schools of yellowtail kingfish cruising the upper water column around current-swept ridges
Rocky gutters and crevices sheltering red rock lobsters and moray eels
