 Another variety of poi is poi tāniko.In this construction, the outer shell was made of finely woven muka using a pattern based on a fishing net; these poi sometimes included strands that were dyed yellow to form a diamond pattern known as Te Karu ō te Atua (the Eye of God).In the late 19th century and the first half of the 20th century, a cottage industry developed from the manufacture of raupō poi for sale to tourists, especially in the Rotorua area.
