The Bethells Dunes Nature Reserve at Te Henga / Bethells Beach protects one of the most significant active sand dune systems on Auckland’s west coast. This endangered coastal ecosystem supports native sand-binding plants such as spinifex and pīngao, along with shorebirds including the New Zealand dotterel. The dunes form part of the wider Te Henga area within the Waitākere Ranges Regional Park and impound the freshwater Lake Wainamu behind the beach. Entry is free and the reserve is managed by Auckland Council.

About Bethells Dunes
The Bethells Dunes biodiversity focus area covers approximately 90 hectares of vegetated and mobile sand dunes at Te Henga / Bethells Beach. The dunes are classified as spinifex and pīngao grassland and sedgeland (ecosystem type DN2), an endangered dune ecosystem in the Auckland region. Native sand-binding species spinifex and pīngao anchor the foredunes, while the system transitions inland to back dunes, scrub, and wetland areas.
The inland extent of the dune system has impounded Lake Wainamu, the largest natural lake in the Waitākere Ranges. This dune-impounded lake provides a calmer swimming alternative to the surf beach. The dunes are recognised as a landform of regional significance due to their extent and the presence of the lake.
Community volunteers and Auckland Council carry out ongoing restoration, including weed control, replanting of native species, and animal pest control. These efforts have supported the recovery of breeding populations of native birds on the dunes and beach.
Wildlife
Tūturiwhatu (New Zealand dotterel) breed at Bethells Beach, with pest reduction programmes aiding their recovery. The foredunes and coastal margin support pipits, terns, and waders. Back dunes and connected wetland areas provide habitat for threatened species including mātātā (fernbird) and matuku-hūrepo (Australasian bittern).
Access and Safety
Bethells Beach is a west coast surf beach with powerful waves and hazardous swimming conditions. Visitors should check current surf and water quality information before entering the water. There is no mobile phone coverage at the beach, so plan accordingly. The road to Bethells includes single-lane sections, and the main car park can fill early on summer weekends. Dogs face seasonal restrictions on the beach during dotterel nesting periods; check signage for current rules.
What Visitors Often Say
The dramatic black sand dunes and the short walk to the sheltered Lake Wainamu create a striking contrast with the wild surf beach. Many appreciate the sense of remoteness and the opportunity to see native birds in a restored dune environment.
Visitors note the limited parking and lack of facilities but value the natural setting and the chance to explore the dunes and lake on foot. The area feels peaceful outside peak summer periods.
