Nikau

Botanical name:  Rhopalostylis sapida
Maori name:  Nikau
Common name:  Nikau Palm
Height:  10 metres

Nikau is the only native palm in NZ and is the southern most palm in the world. 

It is abundant in lowland forests in the North Island and appears as far south as Banks Peninsula. It is also present on the Chatham Islands. 

Nikau fronds are up to 3m long and consist of numerous narrow pointed leaflets up to 1m long.

The small pink flowers are unisexual, with both sexes bunched into a dense panicle called a spadix, which appears at the base of the fronds. Flowering occurs during summer. The red berries, formed from female flowers, take about a year to ripen.


Maori used the palm fronds for thatching dwellings and the leaflets as a lashing material. The growing tip of the plant is edible but its removal always leads to the plant’s demise.


Rhopalostylis is an endemic genus with 2 species. R. baueri is found on the Kermadec islands plus a small population on Norfolk Island. Work is still being done on the genus as the differences between the two species are minimal.


The easiest place to see nikau on Tiritiri is on the Wattle Track, at the low-lying damp area between the hihi feeder and the first water trough (when coming from the wharf).
