Autetaranga
The Autetaranga plant is found in Zone C of the coastal dune system.
Also known as Sand Daphne or Pimelea villosa, Autetaranga is a unique plant endemic to New Zealand. This sprawling shrub is typically found in sandy coastal areas, where it plays a crucial role in stabilising sand dunes. The plant features hairy branches, pointed leaves, and small white flowers, which can produce fruit in various colours, including black, red, pink, or white. Despite its resilience in harsh coastal environments, Autetaranga is currently classified as At Risk – Declining due to threats such as habitat loss, grazing by possums, and seed predation by rodents.

In addition to its ecological importance, Autetaranga holds cultural significance for the Māori people. The plant is known in Māori as Autetaranga or Autetauranga and has been used traditionally for decorative purposes, such as making ribbons or ear ornaments. However, it was not as commonly utilised as other plants like the paper mulberry or Hoheria Populnea. Conservation efforts are ongoing to protect and restore this valuable species, ensuring that it continues to thrive in its natural habitat and maintain its role in both the ecosystem and Māori culture.

Autetaranga near South Track, Waikawa Beach
There are at least three plants sited in the Waikawa beach area, two are north of the river, one to the south. It is supposed to be difficult to propagate from seed, but it is thriving and propagating profusely all year round in the Foxton Beach Dune Garden.
Members of the Waikawa Beach Environmental Group collected some seeds in early January 2025, and currently have at least 30 seedlings growing at a secret location. We also provided some seeds to the Otaki group, but have not heard their progress.
