OHINAU ISLAND - Goat Island & Hauraki Gulf

Robs Bottom is a decent deep-water ridge south of Tofo Beach. We’ve seen it peak around 23 meters, dropping to 28 at its edges, and it’s one of those sites that keeps you guessing. The draw here is often the bigger stuff, with oceanic manta rays making regular appearances, sometimes alongside the elusive small-eye stingray if you’re particularly lucky. Look out for honeycomb morays peering from crevices and loggerhead turtles gliding by. Visibility averages 12 meters, so it’s more about the encounters than the wide-angle reef shots.
