hīnau with oily fruit that fed generations of Māori

Size
Height: 15–20 m
Lifespan
200–400 years
Diet
Not applicable as this is a tree. Absorbs nutrients through roots. Prefers fertile, well-drained soils with high rainfall. Often found with tawa, pūriri, and kohekohe in mature native forest.
Habitat
Lowland forests, coastal scrub, and forest margins. Prefers fertile, well-drained soils with high rainfall. Often found with tawa, pūriri, and kohekohe in mature native forest.
Range
Found in lowland forests of the North Island and northern South Island. Most common in coastal and lowland forests from Northland to Marlborough. Also found on the Chatham Islands.
Endemism
Endemic
Main Threats
Habitat loss from land clearance for farming and forestry. Predation of seeds by introduced rats and possums. Competition from invasive weed species. Climate change affects flowering and fruiting patterns.
Population
Populations stable in remaining forest fragments. Not commercially logged but threatened by habitat loss and possum browsing. Rats consume fruit, reducing regeneration. Protection of lowland forest is critical.
Conservation Status
Not Threatened
Human Risk
harmless
Handling Note
native broadleaf tree, edible fruit safe to handle
Conservation Note
Endemic tree; widespread in lowland and montane forests throughout New Zealand.

Te Ao Māori
In Māori tradition, hīnau fruit was a valued food source, especially for forest-dwelling tribes. The cakes made from dried kernels could be stored for long periods. They provided sustenance during winter months when other foods were scarce. The black pigment from the bark was highly prized for moko (tattoo) and for decorating carved items.
Leathery leaves have serrated edges. Hīnau is a medium-sized forest tree. Its bark was used by Māori to make pātua (food containers) and black tattooing pigment. The fruit was an important food. Māori pounded or soaked the fruit to remove the flesh from the stones. They dried the kernels. Then they baked them into large cakes for storage and travel. The wood is heavy and durable. It was sometimes used for tool handles. The leaves are another clue. Hīnau leaves are oblong, leathery, and sharply toothed along the edges. They look like a serrated knife. They are dark green on top and paler underneath. They arrange alternately along the branches. The tree is evergreen. It holds its leaves through the year. The flowers are small, white, and bell-shaped. They hang in clusters from the branches. They appear in spring. They cover the tree in a cloud of white. The flowers are rich in nectar. Bees and other insects pollinate them. The fruit is a small, purple-black drupe. It is about the size of a large olive. The flesh is thin and bitter. But the kernel inside is rich and oily. Hīnau was one of the most important food trees for Māori. The kernels were collected in autumn. They fell from the trees. They were soaked to soften the bitter flesh. Then the stones were cracked open to remove the kernel. The kernels were dried in the sun. Then they were baked in a hāngī (earth oven) for several hours. The resulting cakes could be stored for months. They provided a reliable source of food during the winter. The wood of Hīnau is heavy, dense, and dark brown. It was used for making tools, for the handles of adzes, and for the frames of houses. It is a wood that does not crack or warp. It is a wood that lasts for generations. To see a Hīnau in flower is to see a cloud of white in the green of the forest. To taste its kernel is to taste the history of the forest. It is the food that sustained the people who lived among the trees. Hīnau is not a king. It is not a warrior. It is the provider. It is the tree of the kernel. The one that fed the forest.
