Litsea calicaris is the only New Zealand representative of the genus Litsea which consists of 200–400 species of evergreen or deciduous trees or shrubs in tropical and subtropical Asia, Australia, North America and South America. It endemic to the Three Kings Islands and the top half of the North Island of New Zealand. It is commonest in the southern part of its range which is from about Mokau in the west to Mahia Peninsula in the east.
Litsea calicaris is a much branched stout tree with a spreading crown and it can grow up to 18m in height. It usually has a single trunk (80cm diameter) with smooth dark greyish brown bark that often harsh lichens often growing on it.
It has 5–15 centimetres long oval opposite leaves that are leathery with wavy margins. During September – November it produces small yellow dioecious sweet-scented yellowish flowers in umbels of 4 to 5.

Litsea calicaris produces a high-quality timber with excellent strength and flexibility. The wood is white, firm, and strong, combining toughness with elasticity and lightweight. In the 19th century, it was used for many purposes including the making of barrels and wheels, and for boat frames, railway carriages and sporting goods, agricultural implements, bullock-yokes, oars, ships' blocks. It also produces a high-quality sliced veneer. It is used are in the making of violins and for the ribs of kayaks. It was also used on the 9th floor of the Beehive building (the executive wing of the Parliament of New Zealand). 

The Māori are said to have used it for its medicinal properties in midwifery. They used it to create a vapour bath (with kōhutuku and tātarāmoa) to promote lochial discharge (Bennett 1883; Goldie 1905).
