The mighty kauri tree has been officially re-classified as a threatened species for the first time. Pōhutukawa, mānuka, and rātā have also been classed as threatened as a precaution, due to the spread of myrtle rust disease.

Why are kauri trees dying?

The disease is caused by a microscopic fungus-like organism, called Phytophthora agathidicida (PA). It lives in the soil and infects kauri roots, damaging the tissues that carry nutrients and water within the tree, effectively starving it to death.
