Even within the Ngāi Tahu tribe there were feuds and rivalries that led at times to bloodshed, and even to open warfare. The most important of these outbreaks — a bloody feud that developed into civil war — began between 1810 and 1815, about the time of the first contacts of European flax-traders with the Māori of Banks Peninsula. This was known as the "kai-huanga" or 'eat-relation' feud, which, by destroying the Ngāi Tahu in Canterbury, effectively prepared the way for their conquest in 1832 by Te Rauparaha.
