The Karekare Dunes Nature Reserve at Karekare Beach protects one of the remaining active sand dune systems on Auckland’s west coast — a stretch of coastal habitat supporting native sand-binding plants and shorebirds within the Waitākere Ranges Regional Park. The dunes at Karekare are classified as an endangered ecosystem type (spinifex and pīngao grassland and sedgeland, ecosystem DN2) and are managed as a Biodiversity Focus Area. Entry to the beach and dunes is free.

About Karekare Dunes
The dunes at Karekare are part of a dynamic coastal system driven by the powerful south-westerly swells and currents that characterise Auckland’s west coast. Black ironsand — the dark sand typical of west coast beaches — is transported northwards along the coast and deposited in substantial quantities, and the dune ecosystem has expanded significantly in recent decades as a result of this ongoing sediment movement. The dune system now extends as a connected coastal feature from Whatipū northward through Karekare.
Native sand-binding species wīngao (a golden sand sedge, Ficinia spiralis) and spinifex (Spinifex sericeus) anchor the foredunes, creating the structure that allows the dune system to persist against wind and wave action. Both are native species increasingly rare on New Zealand beaches due to competition from exotic grasses. Marram grass and lupin — both introduced — are also present at Karekare and are subjects of ongoing management to protect the native dune flora.
Wildlife
The foredunes and coastal margin provide habitat for tūturiwhatu (New Zealand dotterel), pipit, species of tern, and wading birds. The back dunes and wetland areas behind the beach support threatened native wetland species including mātātā (fernbird) and matuku-hūrepo (Australasian bittern). The Karekare Stream and its adjacent wetland areas form part of a connected habitat corridor running through the valley.
Conservation at Karekare
Karekare Landcare, established in 2018, coordinates community-led conservation in the area — focusing on weed management, habitat restoration, and raising awareness of the ecological values of the beach and surrounding catchment. The group works alongside Auckland Council and connects with the broader network of Waitākere Ranges conservation projects.

FAQ
What is the Karekare Dunes Nature Reserve?
The active sand dune system at Karekare Beach on Auckland’s west coast — an endangered coastal ecosystem managed as a Biodiversity Focus Area within the Waitākere Ranges Regional Park.
Is there an entry fee?
No — entry to Karekare Beach and the dunes is free.
Is swimming safe at Karekare Beach?
Karekare is a west coast surf beach with powerful and unpredictable surf. It is patrolled by a surf lifesaving club on summer weekends, but conditions vary significantly. Always check conditions and swim between the flags when patrols are operating.
What makes the Karekare dunes ecologically significant?
They represent one of the remaining examples of an active coastal dune ecosystem in the Auckland region — supporting native sand-binding species like pīngao and providing habitat for threatened shorebirds including New Zealand dotterel.
How do I get to Karekare?
Via Karekare Road, accessed from Piha Road in West Auckland. The road is narrow and winding — allow extra travel time. The journey from central Auckland takes approximately 45–50 minutes.
Karekare Dunes is one of the nature reserves covered in the Auckland parks and reserves guide. For another west coast dune ecosystem, see the guide to Bethells Dunes Nature Reserve at Te Henga.
