Pā kahawai are trolling lures designed to attract and hook large surface-feeding fish, such as kahawai (Arripis trutta). Adapted from Polynesian trolling lures, pā kahawai are composite lures typically constructed using a ground and shaped pāua (New Zealand abalone) shell lure set in a wooden shank with a bone barb fixed at the base and bound tightly with muka (flax fibre) cord.
