Why dive here
With 72+ marine species recorded in the area - including blue sharks, dolphins, hammerhead sharks, humpback whales and seahorses - Jones Bay offers some of Goat Island & Hauraki Gulf's richest reef diving. Water ranges 15-21°C, warmest January, February, March.
Jones Bay isn't about dramatic drop-offs or technicolour corals. It’s about getting to know the quieter side of the Hauraki Gulf, perfect for those days when the weather's a bit frisky or you just want an easy, unhurried dip. We love it as a place to really slow down and appreciate the small stuff. The maximum depth of 7 metres makes it incredibly accessible, and the sandy bottom is a treasure hunt for keen eyes. You’ll often spot stingrays gliding past, their shapes barely disturbing the sand, or eagle rays elegantly flapping their wings. Look for octopus tucked into crevices, their skin rippling with camouflage, and nudibranchs, tiny jewels against the rock. The reef structure itself provides a nice bit of shelter, and you’ll find schools of snapper and kingfish hanging around, especially if there's a gentle current. Visibility averages around 5 metres, which, for New Zealand, means you’re often seeing things pretty clearly – a comfortable, gentle blue rather than a murky green. It’s our pick for a relaxed afternoon dive, or for anyone building confidence in the water.
