The Tawharanui Marine Reserve was established in September 2011. The 400 hectare marine reserve replaces the existing Tawharanui Marine Park, which has been a no take fishing area since 1981. The reserve allows marine life to flourish. You don’t have to swim far to find a nest of crayfish all sitting there blatantly, as if they know they are safe. Tawharanui is a perfect dive site for beginners to feel safe and enjoy the dive while those more advanced will always find something new to admire. Come and book on a charter with New Zealand Diving to experience our fabulous underwater world. We offer a one day dive charter to Tawharanui marine reserve which includes two dives.
Why not take advantage of our destination combo and include this tour in your selection!


New Zealand’s first marine reserve, better known as Goat Island was created in 1975 and officially opened in 1977.

Goat Island or Te Hāwere-a-Maki is a tiny island (approximately 1 hectare or 2.5 acres) in New Zealand located close to the North Island coast, north of Auckland, northeast of Warkworth, and directly west of Little Barrier Island. It is within Cape Rodney-Okakari Point Marine Reserve.

The island is spiritually significant to the local Māori tribe, Ngāti Manuhiri, because their ancestral waka (canoe), Moe Karaka, is said to have landed nearby

Famous for its big Snapper, blue Maomao and many other species of fish in easy access to shore. On the exposed side of Goat Island there is a drop off which offers a variety of life or you can dive in the more sheltered eastern side of Goat island. Its suits all abilities and is a perfect way to relax and take in the amazing underwater environment.

The marine reserve is ideal for children to experience snorkelling and see marine life in numbers not seen anywhere else on the coast.


New Zealand Diving offers a one day charter to our marine reserves with two Dives. Dive from our boat Midnight diver and get to see areas unreachable from the shore. See the wild side of Goat Island.
