Why dive here
With 72+ marine species recorded in the area - including blue sharks, dolphins, hammerhead sharks, humpback whales and seahorses - MAHURANGI IS/ GOAT IS offers some of Goat Island & Hauraki Gulf's richest reef diving. Water ranges 15-21°C, warmest January, February, March.
Mahurangi Island, more commonly known as Goat Island, offers a surprisingly charming dive. Forget the grand wrecks of Truk Lagoon, these aren't the Queen Mary. Instead, you'll find a couple of old tractors sunk years ago, now softened by time and marine growth. We love poking around the cabins, imagining them still hauling across some muddy paddock. The real beauty here is the macro life and the sense of calm. Look closely, and you’ll spot a colony of triplefins darting in and out of every nook, alongside curious spotties and the occasional lemon sole camouflaged on the sand. Visibility hovers around 8 metres, which, for New Zealand, is pretty decent, and the maximum depth of 13 metres makes it an ideal spot for newer divers to gain confidence without feeling overwhelmed. We've often seen eagle rays glide past, a quiet, graceful moment in the blue, and small schools of squid will often hover nearby, their colours shifting with every pulse. It’s an easy, sheltered dive, a reliable favourite when the Hauraki Gulf decides to throw a tantrum.
