Ghosts and spirits in Maori culture
The topic of ghosts and spirits (kehua) in Māori culture is often considered a tapu subject, yet many Māori legends contain mentions of apparitions and paranormal occurrences. It is claimed that long deceased family members may appear to warn of upcoming danger, such as with the famous phantom canoe in 1886 that many reportedly saw on Lake Tarawera, that is believed to have been an omen for the volcanic eruption that occurred eleven days later.
Kikokiko are known in Maori belief as malevolent ghosts that take possession of living people, making them lose sanity. Taniwha are guardian monsters that reside in bodies of water such as rivers or lakes and can appear as sharks, whales, dragons or even floating logs.
Following a death in Māori tradition, the body of the dead is returned to their whanau (family) as soon as possible. The whanau are then called onto a Marae for a tangi (funeral) to remove sadness and clear the spirits. The ghosts and spirits are called to join those who are already living in the afterlife. It is believed that if certain rituals are not conducted, the whanau of a dead person are likely to face stress and unhappiness and if the spirits are not satisfied, they may choose to take someone else.
Sometimes, when a person was nearing death, beyond hope of further living, a procedure known as Tuku Wairua was traditionally performed by a Māori priest who helped the spirit leave the body so that the spirit would not become restless and wander. In modern times, a relative familiar with the procedure may perform a Tuku Wairua; however priests may still be called to give the dying person a holy blessing. Many Māori people believe that the spirits of the gods and the dead are watching the living. For this reason, Māori families will traditionally hold unveiling services and blessings of gravestones of those who have been gone for a year or longer as a way of remembering and paying respects to those who have died.
Spirits Bay and afterlife
Spirits Bay, believed to be one of the most haunted spots in New Zealand and a famous spot for supernatural beings, is considered a sacred place in Māori culture because according to local legend, spirits of the dead depart from this world to their ancestral home (or the afterlife)  from a pōhutukawa tree at the very tip of Cape Reinga. Upon reaching the tree, the spirits travel down a root to the sea below before uniting with their ancestors.
Fairy folk and forest spirits
In Māori belief, there are fairy folk and forest spirits. For instance, Maero is an evil fairy inhabiting forests in the South Island of New Zealand. Patupaiarehe are hilltop-living fairy beings resembling humans in appearance. Turehu are pale-skinned ghostly people living in woodland areas.
