The Miranda Naturalists' Trust is a charitable trust, that established and maintains the Miranda Shorebird Centre, located at Pūkorokoro / Miranda on the western shore of the Firth of Thames on the North Island of New Zealand. The Miranda Naturalists' Trust (MNT) was formed in 1975 to encourage people to visit the coastline and appreciate its wide range of flora and fauna. The trust promotes education and public awareness of coastal ecology, shorebird research and conservation.
