formerly included in Metrosideros polymorpha and Metrosideros villosa Metrosideros kermadecensis, with common names Kermadec pōhutukawa and New Zealand Christmas bush[1] is an evergreen tree of the myrtle family which is endemic to the volcanic Kermadec Islands about 900 km (560 mi) north-east of New Zealand.

The tree produces a brilliant display of red flowers, made up of a mass of stamens and is the dominant forest tree on Raoul Island, growing to 15 m or more.

It is very similar to, and often confused with, the pōhutukawa of mainland New Zealand, differing mainly by having smaller, more oval leaves, and by flowering throughout the year.

Because it is endemic to a small group of islands, Metrosideros kermadecensis is listed as range restricted, but is not regarded as threatened.

Metrosideros kermadecensis is widely cultivated in New Zealand and has naturalised in Hawaii.
