Hammerhead
Seasonal hammerhead boat dive in the Hauraki Gulf
Boat charter to a fingered North Island reef with kelp beds, swim-throughs, and seasonal hammerhead encounters.
About Hammerhead
Hammerhead is a boat dive off the Hauraki Gulf that runs along a fingered reef with rocky shallows, kelp beds, and a small arch. The site is a seasonal hammerhead charter target, but the reef also holds rays, trevally, kingfish, kahawai, and other local fish, so the trip works as both a wildlife outing and a structured boat dive. It suits certified divers who are happy with charter logistics, seasonal timing, and a colder-water New Zealand profile where the main draw is the animal movement rather than coral.
