Few records survive of the extensive body of Māori mythology and tradition from the early years of European contact. The missionaries had the best opportunity to get the information, but failed to do so at first, in part because their knowledge of the language was imperfect. Most of the missionaries who did master the language were unsympathetic to Māori beliefs, regarding them as 'puerile beliefs', or even 'works of the devil'. Exceptions to this general rule were Johan Wohlers of the South Island, Richard Taylor, who worked in the Taranaki and Wanganui River areas, and William Colenso who lived at the Bay of Islands and also in Hawke's Bay. Their writings are valuable as some of the best sources for the legends of the areas where they worked.
