Laurelia novae-zelandiae, commonly known as Pukatea, is a species of tree endemic to New Zealand. Belonging to the monotypic genus Laurelia in the family Atherospermataceae, Pukatea is renowned for its towering stature, lush foliage, and cultural significance to the indigenous Māori people.

Pukatea trees typically grow in wetland areas, including swamp forests and riverbanks, where they thrive in the moist, fertile soils of New Zealand’s temperate climate. These trees can reach impressive heights, with mature specimens often exceeding 30 meters (approximately 100 feet) in height, making them one of the tallest trees in New Zealand forests.

The leaves of Pukatea are glossy and dark green, with a distinctive lanceolate shape and serrated margins. The tree produces small, inconspicuous flowers that give way to spherical fruits containing numerous seeds. The bark of mature trees is rough and furrowed, providing habitat for various epiphytic plants and mosses.

In addition to its ecological importance as a habitat and food source for native wildlife, Pukatea holds cultural significance to the Māori people. The bark of the tree was traditionally used by Māori healers for its medicinal properties. It was brewed into a tea or infusion and ingested as a treatment for various ailments, including stomachaches, fevers, and infections.

Furthermore, Pukatea is revered in Māori mythology and folklore, where it is often associated with spiritual and ancestral connections. The tree is considered tapu (sacred) by some Māori tribes, and its wood was used in the construction of waka (canoes) and other ceremonial objects.

Today, Pukatea continues to be valued for its ecological and cultural significance. Conservation efforts aim to protect and restore wetland habitats where Pukatea grows, ensuring the survival of this iconic species and the biodiversity it supports.

Additionally, the cultural importance of Pukatea remains strong among the Māori people, who continue to honor and respect the tree as an integral part of their heritage.
