Dive-site story
Off the eastern Coromandel Peninsula near Mercury Bay, Ohinau Island drops into rocky reefs and dense kelp forests. Jumbled seabed boulders form swim-throughs and overhangs washed by oceanic currents that draw pelagic predators alongside schools of coastal fish.
Volcanic boulders and kelp canopies sheltering native reef species
Blue maomao and sweeps swirling around rocky ridges
Crevices sheltering packhorse and spiny rock lobsters
Yellowtail kingfish patrolling offshore current lines
