Motuwheteke Island is a boat-access rocky reef in the Bay of Islands with a split profile that lets divers choose between a shallower boulder-and-kelp face and a deeper side that drops into sand. Expect schooling reef fish, sweep and demoiselle, and occasional larger pelagic visitors over rugged reef structure. The site works well as a charter dive because the two faces let teams match the plan to comfort level, while the deeper side rewards careful buoyancy and conservative gas management.
