Kauri

Agathis australis

Also known as New Zealand Kauri, Southern Kauri

Kauri are majestic coniferous giant trees native to northern New Zealand, famed for their massive trunk girths and smooth grey bark that sheds in thick flakes. Mature trees form dense canopy emergent crowns, shedding sticky resin that hardens into amber-like kauri gum on the forest floor over centuries. Today, these ancient ecosystem anchors face severe pressure from kauri dieback disease, a microscopic soil-borne pathogen that starves trees from the roots up.

Very high

Why interaction risk is low: Safe to observe at a normal distance; stay on boardwalks to protect roots from kauri dieback.
What to notice: Recognizable by immense straight grey trunks, flaking bark, and elevated canopy crowns dominating northern forests.
Support conservation: Always use scrub stations to sanitize gear before entering and leaving sanctuaries, and never step off marked boardwalks.

Responsible observation

Clean gear: Thoroughly wash footwear and hiking poles at cleaning stations before and after forest visits.
Stay on tracks: Remain strictly on boardwalks to prevent spreading soil pathogens to shallow root zones.
Look up: Admire the massive canopy emergent branches without touching or stepping near the base.
