Food
Berries an important food source.
See detailed section in Best 1942. Gathering, various preparation processes described (East Coast and Waikato). Commonly, berries pounded, sieved, made into meal, steamed, stored in water. Meal not steamed in flax baskets, as they imparted a bitter flavour. Tī, kiekie, rangiora, raureka, Astelia, Collospermum, ferns used. See also Best 1902.
Many authors discuss the use of berries for food: Kirk, in Taylor 1870 ; Bretts Guide 1883 ; Colenso 1868a, 1868b; Neil 1889.
Other detailed sections are in Colenso 1880 ; Taylor 1855.
"..though commonly eaten by the natives, it has a very harsh taste." (Taylor 1847)
Hīnau berries were covered with water in a wooden trough and left to soak. "The mass was then rubbed between the hands, and the skin and nut were strained out and the water carefully drained away, leaving a kind of coarse meal which was made into a large cake and cooked for several hours in a hangi. The old Māori considered it a great luxury." (Makereti 1938)
Kernel hard and nutritious (Servant 1973).
"In appearance this food when cooked is dark in colour, and looks both solid and heavy. It somewhat resembles a dried linseed poultice" ( Best 1902).
Dyes
Bark provides a brown dye, mixed with iron in paru swamps to make a bright and durable black. Described by many authors: Taylor 1855; Kirk, in Taylor 1870 ; Reed and Bretts 1874 ; Bretts Guide 1883 ; Colenso 1868a, 1868b; Neil 1889 ; Nicholas 1817 ("enou") ; Craik 1830 ("henow") ; Yate 1835 ; Wade 1842 ; Dieffenbach 1843 ; New Zealand Journal 1846;
Hīnau widely used in dyeing. Water in which pounded bark steeped seems to act as a mordant. An exudation from the tree employed in the preparation of black tattooing pigment. Said to prevent tattoos from fading. "In my own youth, we were wont to make writing ink from this bark" (Best 1907, 1942).
Bark used to stain flax samples (Flax Exhibition Catalogue 1871)
Mordant composed of aluminous clay (Colenso 1868a 1868b)
Bark used by a few inland Māori tribes for dyeing flax cloths (Cheeseman 1906)
Nicholas 1817 (p.340) described the vessel used to dye fibre in.
Dyeing processes also described in Best 1898.
"Hangehange, the bark used as a black dye" (Taylor)
Fishing and hunting
In Best 1925: Carved prow and stern posts of canoe could be blackened by steeping in hīnau dye for (usually) two nights, then thrown in a parapara swamp for a night. Then smeared with oil or grease. Black colour was approved of and was permanent. (Hare Hongi, Northern Māori). Canoe bailers.
Domestic
Bark used to make large bags used during preparation of raupō pollen for bread (Taylor 1855).
Hīnau used as a wedge to jam greenstone into hole on sawing block. Hīnau has a strong, tough grain, but is soft enough to bend to form of stone (Best 1912 p.12).
Bark sometimes used for small water vessels (Best 1942).
Young, tough saplings such as hīnau sometimes tied with a knot. Cut later when the desired size and made into walking sticks (Best 1907).
Among museum artefacts he tested Wallace 1989 found 2 teka made of hīnau.
Hītari or tātari are specially made harakeke baskets for sieving meal (renga) of hīnau berries.
Construction
Cabinetmaking (Colenso 1868a) (N.B. - details on post-European timber uses generally not included in this database).

".. if not near a Suphur Spring, he makes a hot bath of water, adding a decoction of the bark of the Hinau. This is said to cure the severest skin disease" (O"Carroll 1884)

Seeds good source of essential fatty acids, generally regarded as protective against cardiovascular disease. (Cambie, Ferguson 2003)
