In the 1840s Edward Shortland, Sir George Grey, and other non-missionaries began to collect the myths and traditions. At that time many Māori were literate in their own language and the material collected was, in general, written by Māori themselves in the same style as they spoke. The new medium seems to have had minimal effect on the style and content of the stories. Genealogies, songs, and narratives were written out in full, just as if they were being recited or sung. Many of these early manuscripts have been published, and scholars have access to a great body of material (more than for any other area of the Pacific) containing multiple versions of the great myth cycles known in the rest of Polynesia, as well as of the local traditions pertaining only to New Zealand. A great deal of the best material is found in two books, (The Deeds of the Ancestors), collected by Sir George Grey and translated as "Polynesian Mythology"; and "Ancient History of the Māori" (six volumes), edited by John White.
