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 — an endangered coastal ecosystem supporting native sand-binding plants, shorebirds including New Zealand dotterel, and the dune-impounded lake of Wainamu behind the beach. The dunes are part of the wider Te Henga / Bethells Beach area within the Waitākere Ranges Regional Park. Entry to the beach and dunes is free; the area is managed by Auckland Council.

About Bethells Dunes
The dunes at Te Henga are classified as spinifex and pīngao grassland and sedgeland (ecosystem type DN2), considered an endangered dune ecosystem in the Auckland region. Pīngao — a native golden sand sedge — and spinifex are the two primary sand-binding species found on the foredunes here, anchoring the mobile sand and creating structure for other species. Marram grass and lupin, both exotic species adapted to dune environments, are also present and are the subject of ongoing management.
Behind the foredunes, the system transitions to back dunes and a wetland area backing Lake Wainamu — a lake formed where the dune system has impounded a stream. The lake is accessible via a short walk from the main beach car park. In the last few decades the dune ecosystem has expanded significantly as black ironsand characteristic of the west coast is transported northwards by prevailing south-westerly swells and deposited in large quantities.
Wildlife
Tūturiwhatu (New Zealand dotterel) breed at Bethells Beach — pest reduction in the area has helped the population recover. On the foredunes and coastal margin you’ll find pipit, species of tern, and waders. The back dunes and wetland areas support threatened native wetland species including mātātā (fernbird) and matuku-hūrepo (Australasian bittern), which also inhabit the connected Te Henga wetlands and conservation areas to the south.
What to Know Before You Visit
Bethells Beach is a west coast surf beach — conditions can be rough and swimming can be hazardous. There is no mobile phone coverage in the area. The car park gate has set closing times, so plan your visit accordingly. The road into Bethells is single-lane in sections. During summer weekends the car park fills early.
