Both species and their cultivars have now been widely distributed to temperate regions of the world as ornamental garden plants – and to lesser extent for fibre production.
Leaves were cut near the base of the plant using a sharp mussel shell or specially shaped rocks, more often than not greenstone (jade, or pounamu).
The green fleshy substance of the leaf was stripped off (the waterproof para),[3] again using a mussel shell, right through to the fibre which went through several processes of washing, bleaching, fixing, softening, dyeing and drying.
The handmade flax cording and ropes had such great tensile strength that they were used to successfully bind together sections of hollowed out logs to create huge ocean-going canoes (waka).
The nets were woven from green flax, with stone weights and light wood or gourd floats, and could require hundreds of men to haul.
The dried flower stalks, which are extremely light, were bound together with flax twine to make river rafts called mokihi.
The gum-like sap produced by harakeke contains enzymes that give it blood clotting and antiseptic qualities to help healing processes.
It is a mild anaesthetic, and Māori traditionally applied the sap to boils and various wounds, to aching teeth, to rheumatic and associated pains, ringworm and various skin irritations, and scalds and burns.
Splints were fashioned from korari (flower stalks) and leaves, and fine cords of muka fibre utilise the styptic properties of the gel before being used to stitch wounds.
[7] Chemical analysis shows the antifungal, anti-inflammatory drug,[8] musizin, and laxative anthraquinones are in common and mountain flaxes.
Some warriors wore coats of heavily plaited Phormium tenax, which gave defense characteristics similar to a medieval gambeson, slowing musket balls to be wounding rather than deadly.
[15] Several times the possibility of commercial papermaking from the fibre from Phormium tenax has been investigated, but currently it is used only by artists and craftsmen producing handmade papers.
From about the 1860s there was an active industry harvesting and processing flax for export, peaking at 32,000 tons in 1916, but the general depression of the 1930s brought the virtual collapse of this trade.
[22] Many others patented variations, but the basic design was that leaves were fed between rollers, then hit by iron beaters, revolving faster than the feeder, thus stripping the epidermis from the fibre.
Machinery was estimated at £500 – 8 hp engine with Cornish boiler £200; 4 strippers @ £22, £88; scutching hooks, £15; a screw press £12; building £185.
[40][41][42] Initially unions were resisted, as in the report of an 1891 strike, which said, "Mr Hall intends to proceed to Auckland for the purpose of procuring fresh men to work the mill.
