Tapu is the strongest force in Maori life. It has numerous meanings and references. Tapu can be interpreted as "sacred", or defined as "spiritual restriction" or "implied prohibition", containing a strong imposition of rules and prohibitions. A person, an object or a place, which is tapu, may not be touched by human contact. In some cases, not even approached. A person, object or a place could be made sacred by tapu for a certain time, and the two main types of tapu were private and public. Private tapu concerned individuals, and public tapu concerned communities.
In earlier times, tribal members of a higher rank would not touch objects which belonged to members of a lower rank. This was considered "pollution". Similarly, persons of a lower rank could not touch the belongings of a highborn person. Death was the penalty.
A breach of "tapu" was to commit a hara (violation) could incur the wrath of the Gods. Certain objects were particularly tapu, so much so that it was a dangerous act to even touch them, apart from suitably qualified priests. In 1772 the French explorer Marion du Fresne was killed for breaching a particular "tapu".
