This finely decorated example of this Māori musical instrument is made from maire, a native hardwood.
The picture shows a smaller example of the Māori musical instrument. Pukaea were used to announce relay signals at times of conflict and were also used to announce the rituals associated with the planting of kumara (sweet potato) and other crops.
These Māori musical instruments had a variety of roles from signalling to ceremonial and ritual use.
The longer koauau is made from koiwi toroa/albatross wing-bone; the shorter is made from koiwi kuri/dog bone.
