Māori mythology
Māori mythology and Māori traditions are two major categories into which the remote oral history of New Zealand's Māori may be divided. Māori myths concern fantastic tales relating to the origins of what was the observable world for the pre-European Māori, often involving gods and demigods. Māori tradition concerns more folkloric legends often involving historical or semi-historical forebears. Both categories merge in whakapapa to explain the overall origin of the Māori and their connections to the world which they lived in.
The Māori did not have a writing system before European contact, beginning in 1769, therefore they relied on oral retellings and recitations memorised from generation to generation. The three forms of expression prominent in Māori and Polynesian oral literature are genealogical recital, poetry, and narrative prose. Experts in these subjects were broadly known as tohunga.
The rituals, beliefs, and general worldview of Māori society were ultimately based on an elaborate mythology that had been inherited from a Polynesian homeland (Hawaiki) and adapted and developed in the new setting. Alongside different Polynesian cultures having different versions of a given tradition, often the same story for a character, event, or object will have many different variations for every iwi, hapū, or individual who retells it, meaning there is never a fixed or 'correct' version of any particular story.
