Te katau te tumara. Waist ornament of nautilus shells. This is worn, by girls and young women, on top of the skirt as part of their dance attire. This is made up of two components; te tumara (nautilus shells) and te kora (cordage of sennit fibre). Te kora is made by first creating three sets of two-ply te kora. Subsequently, these are plaited together using three-ply technique, forming the basis of te katau. Off-white tumara, numbered in thirty-four, are worked into te kora by threading and lashing each tumara. Te tumara are perforated for this purpose. A missing shell is indicated by a gap within row of tumara. The remaining kora, without te tumara, are used for tying purposes. Women are tasked with making te katau te tumara, however the perforations are completed by men.
