Nestegis lanceolata is an evergreen tree which grows to 20–50 ft (6–15 m) high. The leathery, glossy, green leaves are narrow spear-shaped, and are 2–6 in (5–15 cm) long. The flowers are small and light green; summer. Red or orange berries, about 0.4 in (1 cm), mature the following summer to autumn.
Nestegis lanceolata is found in lowland to low-mountain forests in the North Island, and locally to the north of the South Island, New Zealand. Also called white maire. It is a member of the olive family.
