Plaiting and weaving (raranga) the flax fibres into baskets were but only two of the great variety of uses made of flax by Māori who recognised nearly 60 varieties, and who carefully propagated their own flax nurseries and plantations throughout the land. 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, again using a mussel shell, right through to the fibre which went through several processes of washing, bleaching, fixing, softening, dyeing and drying. The flax fibre, called muka, is laboriously washed, pounded and hand wrung to make soft for the skin. The cords (muka whenu) form the base cloth for intricate cloaks or garments (kākahu) such as the highly prized traditional feather cloak (kahu huruhuru). Different type of cloaks, such as kahu kiwi and kahu kākā, were produced by adorning them with colourful feathers from different native birds, such as kiwi, kaka (parrot), tui, huia and kereru (woodpigeon).
