Puriri is one of the few native trees with large colourful flowers. Many plants in New Zealand have white or green flowers. The tubular flowers of the puriri look rather like snapdragon flowers and can range from fluorescent pink to dark red, rose pink (most common) or sometimes even to a white flower with a yellow or pink blush. The bright colour, the tube shape, copious nectar production and the hairs at the base of the flower tube all point towards birds pollinating this flower (the hairs stop insects from stealing the nectar).
On the New Zealand mainland there is often plenty of nectar in the flowers because there aren't enough birds to eat all the nectar produced by the tree.
The flower produces a rugged ribbed 'stone' which has scales on 4 sides. When these fall these scales allow moisture to penetrate the wood. This in turn swells the 4 seeds and they can all germinate together pushing the scales aside to emerge as 4 separate individuals clinging to their woody capsule. Generally only one seed will eventually develop into a large tree.

Puriri was actively and selectively logged in the past to provided timber for a wide range of end uses. Only the best trees were felled, leaving the gnarled puriri often found on farm paddocks. This has given the impression that puriri is incapable of growing straight, but early reports of puriri describe naturally clear boles of 4.5 to 9 m and there are still a few trees like that left.

Traditional uses by the Maori
