As part of the resurgence of Māori culture, the traditional crafts of carving and weaving are now more widely practised, and Māori artists are increasing in number and influence. Most Māori carvings feature human figures, generally with three fingers and either a natural-looking, detailed head or a grotesque head. Surface patterns consisting of spirals, ridges, notches and fish scales decorate most carvings. The pre-eminent Māori architecture consisted of carved meeting houses (''wharenui'') decorated with symbolic carvings and illustrations. These buildings were originally designed to be constantly rebuilt, changing and adapting to different whims or needs.
