Hiapo is the barkcloth of Niue, made from the ata (mulberry tree) and used at important events, such as a hair-cutting ceremony. The designs that embellish this fabric come from nature and the people of Niue, rich motifs of the environment and culture. Cora-Allan Wickliffe has documented the patterns of hiapo so that the wonder of this artform can be passed on to new generations.
