The Nature of the Waitakere Ranges


The Waitakere Ranges are 30,000 hectares of bush-covered hills to the west of Auckland, that reach the black sand beaches of the wild west coast and the Manukau harbour. Rain forested peaks of over 300m high which extend to the eastern foothills bordering the suburbs of Auckland city, and also to the coastal villages along the Manukau Harbour and Auckland's wild west coast beaches.

The Waitakere Ranges region is one of our natural treasures, rich in native flora and fauna, and home to the giants of the forest, the mighty kauri tree.

Richness of Waitakere’s Biodiversity

Threats to the nature of Waitakere

The Famous Kauri tree has the kauri dieback disease

This is what it is and what it does.

The pathogens (germs) can sense a kauri trees roots, and swim towards them using a tail-like flagella.

There is no cure for kauri dieback disease, and the disease kills most if not all the kauri it infects. It can be spread by just a pinhead of soil, and you can't tell by looking whether a tree is infected or not. Kauri dieback disease is threatening kauri with functional extinction.

To prevent this disease from spreading there are stations placed at hiking tracks where these trees are located where you can disinfect your shoes and clean them this is a great initiative to help save the kauri trees.

Off course there is more to do and to see around Waitakere. Next to the hike trails and KareKare Falls, there is the beautiful Piha with a black-sand beach which is a great location to learn to surf. There is also Arataki Visitor Centre where you can learn everything about the surrounding of Waitakere. If you are keen to combine all these adventures you can click here.
