Hangatāhua (Stony) River
The Hangatāhua (Stony) River originates from Ahukawakawa Swamp within Te Papa-Kura-o-Taranaki (the national park) and has a very narrow catchment. The river was protected in its natural state by New Zealand’s first Local Conservation Order in 1985, and the Order’s provisions are now embodied in the Regional Freshwater Plan for Taranaki.
It holds special value for Taranaki Iwi. Ecological health has been stable over time, although it is subject to short-term impacts due to erosion events from Taranaki Maunga.
As of October 2020, the Hangatāhua catchment included approximately 294 km of stream bank. At that time, it was estimated that around 83% of the stream banks were planted in riparian vegetation. This included 72% located within Te Papa-Kura-o-Taranaki (the national park) and 11% outside the park boundary under riparian management plans.
