Te ririko. Neck ornament of porpoise teeth. It is made of two material components: wiin te kua kewe (porpoise teeth) and te kora (coconut sennit fibre cordage). A braided cord makes up the neck band. The ends have been knotted to prevent the fibres from unravelling. Each strand of the plaited braid has been utilized to thread a single wiin te kua kewe and then intertwined to perceive a double layered look. The roots of the teeth are matte and a dark off-yellow colour. An internal cavity is visible from the root. The exposed ends of the teeth are polished and off-white in colour. Small perforations have been made with a shark toothed pump drill into the roots of the teeth for te kora to be threaded through. This type of neck ornament can be worn by either men or women at any time.
