The hei-tiki /haɪˈtiːkiː/ is an ornamental neck pendant of the Māori. Hei-tiki are usually made of greenstone and worn around the neck. They are often referred to as tiki, a term that actually refers to large human figures carved in wood, and, also, the small wooden carvings used to mark sacred places. Tourist versions - either from real jade or sometimes from cheap plastic - are also commonly found throughout New Zealand.
The name "hei-tiki" suggests a connection with Tiki, the first man in Māori legend. Hei-tiki may signify memorials to ancestors, or represent the goddess of childbirth, Hineteiwaiwa. The rationale behind the first idea is that they were often buried when their kaitiaki (guardian) died and would be later retrieved and placed somewhere special to be brought out in times of tangihanga (mourning and associated activities). Because of the connection with Hineteiwaiwa, hei-tiki were often given to a woman by her husband's family if she was having trouble conceiving.
The most valuable hei-tiki are carved from New Zealand greenstone, also called pounamu. Pounamu consists of either nephrite or bowenite (Māori: tangiwai). Pounamu is esteemed highly by Māori for its beauty, toughness and great hardness; it is used not only for ornaments such as hei-tiki and ear pendants, but also for carving tools, adzes, and weapons.
