Kanuka is a medium-sized native tree that can grow up to 25 metres tall. It has a slender trunk with rough and flakey bark that can peel off in papery strips. Kanuka leaves are narrow, pointed and prickly, with a unique and distinctive aroma when crushed. Kanuka produces small clusters of small white and pink flowers in summer.
Kanuka is found throughout New Zealand in forests, shrubland and wetlands. It is one of the first tree species to be distributed and is an essential pioneer species.
Kanuka has a range of traditional medicinal uses, including treating colds, cuts, and skin conditions. The bark and leaves were also used for weaving, and the wood was used for firewood and making tools.
Kanuka is an important component of many New Zealand ecosystems and provides habitat and food for many native species, including birds, insects, and lizards. It is also an important species for ecological restoration, as it helps to stabilise soil and prevent erosion.
Silvereye: Silvereyes, also known as waxeyes, are small passerine birds. They are often found in Kanuka forests, where they feed on the nectar, fruit, and insects associated with the tree.
Kereru: Kereru, or New Zealand pigeons, are large, endemic birds known for their distinctive appearance and iridescent feathers. They are known to feed on the leaves, buds, and flowers of the Kanuka tree.

Kanuka is not currently considered a threatened species. However, it is subject to some pest control measures to protect it from browsing by introduced mammals such as deer and possums.
To protect Kanuka and other native species, it is crucial to prevent the spread of pests and invasive species, support local conservation efforts, and practice responsible land use and management.
