BACKGROUND
Kauri
Giant kauri trees were considered by Māori to be the kings of New Zealand’s forest. The straight-grained wood was prized by Europeans as spars for sailing ships and became popular in construction. With logging, tracts of native forest soon dwindled. Today the patches that remain are being carefully protected, and the forest is being restored.

Kauri dieback disease
A major threat to the kauri is kauri dieback, a disease caused by a fungus-like water mould Phytophthora taxon Agathis. The spores of the water mould first attack the kauri roots and then damage the tissues that carry nutrients. The leaves begin to yellow and fall, the canopy thins, branches die, lesions bleed resin at the base of the tree and eventually the tree dies. There is as yet no known cure. The disease has been found in many areas including the Waitākere Ranges, Trounson Kauri Park and Waipoua Forest. In 2012 it was still not detected in the Hūnua Ranges and the Coromandel. Since the spores are carried in soil, the best prevention is to ensure that shoes and any equipment in contact with the soil are clean before visiting a kauri forest. A charter was set up among a number of public agencies to establish a kauri dieback programme and manage the spread of the disease.

Forest Lore
In Māori tradition, people and forests are vitally connected – both were created by the god Tāne. A magical realm guarded by lizards, birds and other creatures, the forest also provided Māori with the necessities of life. They depended on its trees and shrubs for food, medicines, building materials and clothing.
The life force or mauri of a forest could be held within stones and guarded by lizards. Tohunga (priests) recited prayers to protect or increase the mauri. When Māori chopped down trees or took food from the forest, they showed their respect by performing special rites.

Te Ngahere
E ai ki te Māori he hononga ita kei waenganui i te tangata me te ngahere – inarā nā te atua nā Tāne te tangata me te ngahere i auaha. He wāhi mīharo te ngahere, ko te mokomoko, te manu, aha atu, ngā kaitiaki. Ko te ngahere te whakaruruhau, te pātaka kai a te Māori. Ka noho te ngahere me ngā rākau, ngā tipu hei kai, hei rongoā, hei rauemi hanga whare, raranga kākahu hoki.
Ka puritia te mauri o te ngahere ki roto i te kōhatu, te mokomoko rānei. Ka karakia ngā tohunga hei tiaki, hei whakapūmau i te mauri. I mua i te poro rākau, te mahi kai rānei kua tuku karakia.
