Tangihanga, or more commonly, tangi, is a traditional Māorifuneral rite held on a marae. While still widely practised, it is not universally observed in modern times. Each iwi differs on how they honour those who pass. Tangihanga generally take three days with burial on the third day. From the moment of death, the tūpāpaku is rarely alone. The tūpāpaku is transported to the marae. There they are welcomed with a pōwhiri and will lie in state for at least two nights, usually in an open coffin, in the wharenui. Throughout the tangihanga, the tūpāpaku is flanked by the whānau pani , who take few and short breaks, dress in black, and sometimes wreath their heads in kawakawa leaves. Around the coffin, flowers and photographs of deceased relatives are placed. Visitors come during the day, sometimes from great distances despite only a distant relationship, to address the deceased. They may speak frankly of his or her faults as well as virtues, but singing and joking are also appropriate. Free expression of grief by both men and women is encouraged. Traditional beliefs may be invoked, and the deceased is told to return to the ancestral homeland, Hawaiki, by way of te rerenga wairua, the spirits' journey. The close kin may not speak. It is traditional for mourners to wash their hands in water and sprinkle some on their heads before leaving the area where the tūpāpaku lies in state. On the last night, the pō whakamutunga, the mourners hold a vigil and at a time assigned by custom the coffin is closed, before a church or maraefuneral service and/or graveside interment ceremony, invariably Christian in modern times. As with the area the tūpāpaku lies, it is traditional for mourners to wash their hands in water and sprinkle some on their heads before leaving the cemetery. After the burial rites are completed, a hākari is traditionally served. Mourners are expected to provide Koha or gifts towards the meal. After the burial, the home of the deceased and the place where the deceased died are ritually cleansed with karakia and desanctified with food and drink, in a ceremony called takahi whare, trampling the house. That night, the pō whakangahau is a night of relaxation and rest. The widow or widower is not left alone for several nights following. Both in traditional times and modern, the tangi of high-profile individuals can be both extended and elaborate.
