Waipoua Forest

The Waipoua Forest is a forest on the west coast of New Zealand's North Island. It preserves some of the best examples of kauri forest remaining in New Zealand of which it is notable for having two of the largest living kauri trees, Tāne Mahuta and Te Matua Ngahere.

A community-based volunteer organisation, the Waipoua Forest Trust, helps maintain the forest. The sanctuary is bordered to the south by the 350 hectares (860 acres) Professor W.R McGregor Reserve, named after W. R. McGregor (1894–1977). In the 1940s, McGregor, and others, successfully campaigned to end logging of the forest and to have it declared a sanctuary, a status it achieved in 1952.

Approximately 200,000 people visit Tāne Mahuta every year. This has led to concerns about the health of the forest and the spread of kauri dieback disease.
