Tauhinu
The Tauhinu plant is found in Zone B of the coastal dune system.
​
Tauhinu, also known as Ozothamnus Leptophyllus, is a hardy shrub native to New Zealand, commonly found in coastal dune environments. This plant is well-adapted to the challenging conditions of the dunes, including high winds, salt spray, and sandy soils. Tauhinu typically grows to about 1 to 2 meters in height and has slender, needle-like leaves that are covered in fine, white hairs. These hairs help reduce water loss and protect the plant from the harsh coastal elements.

Tauhinu flower
The flowers of Tauhinu are small and white, forming dense clusters at the ends of the branches. These flowers bloom from late spring to early summer, providing a vital source of nectar for native insects. The plant’s ability to thrive in nutrient-poor, sandy soils makes it an important species for stabilising sand dunes and preventing erosion. Its deep root system helps bind the sand, reducing the impact of wind and water erosion on the coastal landscape.

Ecologically, Tauhinu plays a crucial role in the dune ecosystem. It provides habitat and food for a variety of native insects and birds, contributing to the biodiversity of the area. The plant also supports other dune vegetation by creating a microhabitat that offers some protection from the wind and salt spray. This interaction helps maintain the health and stability of the dune ecosystem, making Tauhinu an essential component of New Zealand’s coastal environments.
Despite its resilience, Tauhinu faces threats from habitat loss and invasive species. Human activities such as coastal development and the introduction of non-native plants have significantly impacted the natural dune ecosystems. Conservation efforts are necessary to protect Tauhinu and the unique environments it supports.
