Endemic
Main Threats
Habitat loss from land clearance is the primary threat. Browsing by introduced possums and deer. No significant pest or disease issues. Climate change affecting forest habitats and coastal areas.

Te Ao Māori
In Māori tradition, putaputawētā was known as the home of the wētā. The tree often develops hollows in its trunk where wētā live. The name putaputawētā means many wētā. The hard wood was used for making small tools. Chisels and digging sticks. The berries were eaten by birds. The tree was also known as piripiriwhata. Meaning clinging to the whata (a raised storage platform). Possibly referring to the way the tree clings to forest margins.
Named for its distinctive mottled leaves. Marbleleaf has leaves that look like marble. Pale green with darker green patches. Splotched and speckled. The pattern is irregular. No two leaves are the same. The tree is small. Reaching ten metres at most. It has a rounded, bushy crown. A tree that wears camouflage. The flowers are small and white. Followed by black berries. The berries are eaten by birds. Which spread the seeds across the forest. The tree is a favourite of the kererū. Which wobbles on the branches. Swallowing the berries whole. A tree that gets the birds drunk on fruit. The Māori name tells the real story. Putaputawētā means many wētā. The native insect wētā often lives in holes in the trunk. The tree develops hollows as it ages. And the wētā move in. They hide in the holes during the day. Emerging at night to feed. A single tree might hold dozens of wētā. A tree that is also an apartment building. The wood is hard and durable. Māori used it for making small tools. Chisels. And digging sticks. The wood holds a sharp edge. And does not split easily. A tree that makes good tools. To see a marbleleaf is to see a tree of the forest edge. It grows in the gaps. Along the margins. In the regenerating bush. Its mottled leaves catch the light. Its berries feed the birds. Its hollows house the wētā. It has been here for millennia. It will be here as long as the forest keeps its edges. The wētā will have somewhere to hide. The kererū will have something to eat. The marbleleaf does not ask for thanks. It just grows.
