Anchor Bay is the main beach within Tāwharanui Regional Park on the Rodney coast north of Auckland — a 360-metre stretch of white sand consistently ranked among the best swimming beaches in the Auckland region. The bay sits inside a marine reserve, which means the water is clear and the marine life is abundant. The combination of a safe swimming beach and productive snorkelling in protected water makes Anchor Bay a standout destination, but it requires some planning: the park is gated, facilities are minimal, and there are no shops or stores anywhere nearby.

About Anchor Bay and Tāwharanui Regional Park
Tāwharanui Regional Park occupies a peninsula north of Matakana and Leigh, about 90 minutes from Auckland depending on route. The park is enclosed by a predator-proof fence — New Zealand’s first mainland island sanctuary of this kind — which means the birdlife inside the fence is noticeably richer than in surrounding areas. Kīwi, kŌkako, and saddleback are among the species that have been reintroduced.
Anchor Bay is reached by walking from the main car park through the gate. The walk is easy and flat. The beach itself curves in a classic bay shape with picnic areas nearby. The greywacke rocks at the headlands contain Jurassic-era fossils — large grey-green boulders studded with impressions from creatures that lived here 150 million years ago.
Snorkelling the Marine Reserve
The Tāwharanui Marine Reserve covers the water in front of Anchor Bay. Because fishing and collecting have been prohibited since the reserve was established in 1981, fish populations are significantly higher than in surrounding unprotected waters. Snorkellers regularly see blue maomao, snapper, crayfish, and a range of reef fish species. The reserve recommends wearing a wetsuit or using a flotation device — a boogie board works well — particularly for less confident swimmers.
What Visitors Say
“The combination of the open sanctuary, the beach, and the snorkelling makes Tāwharanui feel completely different from any other park in Auckland. The birds are noticeably present — you hear things you don’t normally hear anywhere near the city. And the snorkelling in the reserve is genuinely brilliant, even for beginners.” — visitor account, Matakana Coast
