Reotahi Bay

Explore the fascinating underwater world of our dive site located at 15 Beach Road, Whangarei Heads, New Zealand. This shore dive offers a maximum depth of 8m, making it suitable for both beginner and advanced divers. Discover the remnants of old mooring blocks and impressive boulders resting on the sandy bottom. As you ascend into the oyster-covered boulders, you'll be greeted by a vibrant sea grass habitat, home to mesmerizing bubble snails, perhaps even spotting a seahorse or pipefish if luck is on your side. The sandy areas are teeming with diverse marine life such as goatfish, snapper, parore, starfish, and if you're fortunate, you may even catch a glimpse of a snake eel.

Please exercise caution while diving in the bay, as this site is also a local launch site for trailer boats. Optimal timing is crucial as you go deeper and encounter the gentle sway of the current. Venturing too far out may expose you to stronger currents and increased boat traffic. Although this dive offers an enjoyable day experience, it truly comes alive during night dives, particularly opposite the oil refinery. Mysterious squid and octopus often roam around the boulders, illuminated by your dive lights, creating a mesmerizing spectacle. Divers may even encounter piper fish curiously darting into your path, bouncing off gently as they explore their surroundings.
