The Pump House - Goat Island & Hauraki Gulf
Wolf Island, and its neighbour Darwin, are legendary for a reason. Drop in here and you’re not just hoping for hammerheads, you’re often immersed in them. We’ve seen hundreds, a swirling vortex of scalloped hammerheads, so many that they block out the sun, a truly disorienting and exhilarating experience. It’s a drift dive, usually around a pinnacle, and the currents can be strong, so you’ll need to be comfortable in the blue. It’s not just hammers, though. We’ve had incredible encounters with Galapagos sharks, seen huge schools of black skipjack and darkfin amberjacks so dense they shimmer like a liquid wall. Keep an eye out into the deeper blue too; we’ve spotted orcas here, and whale sharks are frequent visitors during the right season. This place is for experienced divers who crave big animal encounters and don’t mind a bit of a ride. Come prepared to be humbled by the sheer volume of life.
