Skull Gully Stream is a tributary of Wainuiomata River located within the pristine water catchment area.
Skull Gully Creek winds its way into the Wainuiomata River, flowing through an untouched podocarp rainforest at the heart of the Wainuiomata Water Catchment. The pristine forest here is home to ancient trees that have stood for more than a thousand years, providing a sanctuary for kiwi and other bird species. The exceptional ecological integrity of the forest has spurred plans to transform the area into a super sanctuary. This initiative involves erecting fences to safeguard the delicate balance of flora and fauna, creating a protected haven for wildlife within the remarkable landscape around Skull Gully Creek.
