Waka huia are Maori treasure containers. They are also referred to as Papahou. Historically these sacred boxes were used to store feathers of the Huia bird which were used for hair adornment by chiefs. The feather was stuck in the topknot. Later on also other highly valued possessions (taonga) were kept in Waka huia such as jewelry and hair combs (heru). The waka huia is probably the most valued and revered of all personal carved items.
