Kunzea robusta, commonly known as rawirinui or kānuka,[1] is a tree in the myrtle family, Myrtaceae, and is endemic to New Zealand.

It has rough, stringy, or corky bark, lance-shaped leaves that are darker on the upper surface, flowers in compact groups of up to 30, each with five or six white petals, and about 35 stamens of varying lengths.

Kunzea robusta is a spreading shrub or tree, typically growing to a height of 20–30 m (70–100 ft) with rough, stringy, or tessellated bark, which peels upward in long strips.

[4] The specific epithet (robusta) is a Latin word meaning "hard and strong like oak",[5] referring to the stature of mature trees of this species.

It is mostly found in coastal and low-lying areas and nearby hilly country, especially around forest margins, and does not usually grow in upper montane locations.
