Kauri leaves have no petioles and are arranged alternately. They are thick and leathery with parallel veins and are dull olive-green colour. Juvenile leaves are 5-10 x 0.5-1.2cm; Adult leaves are 2.0-3.5 cm long. Most leaves remain on the tree for 3-6 years. (Ogden and Ahmed 1989), some up to 15 years ( Sylvester and Orchard 1999). The colour of seedling foliage varies from olive green to bronze to red. Reddening is noticeable in naturally regenerating seedlings and nursery- raised stock. It is caused by increased concentration of the pigment rhodoxanthin and is thought to be a response to high light intensity (Peterson 1963)
