The term tiki is applied to carved human figures generally, both by the Maori and by other polynesians.
The name possibly has some connection with the myth of Tiki, the first man created by Tane.
On the other hand tiki or tikitiki is also a general term for carving in many parts of polynesia, as, for instance, in Niue, where the Tiki myth is unknown and human figures were not carved.
In New Zealand, however, tiki is usually applied to the human figure carved in greenstone as a neck ornament. The full name is hei-tiki.
