HOME BAY - GMI - Goat Island & Hauraki Gulf
Mabouya Garden feels like one of those sites you could dive repeatedly and still find something new. We love dropping in on the north side of Mabouya Island, where the reef wall starts around 5m and slopes down to about 17m. It’s an easy dive, making it ideal for those who prefer to really take their time exploring the nooks and crannies. The corals here are in really good shape, a mix of brain and plate corals creating plenty of hiding spots. Keep your eyes peeled for the smaller stuff – we’ve often spotted Blackfin Blennies peeking out from tiny holes and even the elusive Little Post Horn Squid drifting past. French Grunts school tightly in the crevices, and we’ve had good luck with Spotted Soapfish near the sandy patches. While the current description mentions larger pelagics, in our experience, the real magic is in the macro life and the sheer density of reef fish. We’d suggest going slow, hugging the wall, and letting your eyes adjust to the subtle movements. It’s a great spot for photographers keen on patience.
