Māori decorated the white wood of buildings, canoes and cenotaphs using red (a mixture of red ochre and shark fat) and black (made from soot) paint and painted pictures of birds, reptiles and other designs on cave walls. Māori tattoos (''moko'') consisting of coloured soot mixed with gum were cut into the flesh with a bone chisel. Since European arrival paintings and photographs have been dominated by landscapes, originally not as works of art but as factual portrayals of New Zealand. Portraits of Māori were also common, with early painters often portraying them as an ideal race untainted by civilisation. The country's isolation delayed the influence of European artistic trends allowing local artists to develop their own distinctive style of regionalism. During the 1960s and 1970s, many artists combined traditional Māori and Western techniques, creating unique art forms. New Zealand art and craft has gradually achieved an international audience, with exhibitions in the Venice Biennale in 2001 and the "Paradise Now" exhibition in New York in 2004.
