The Hangatahua (Stony) River is sourced from Ahukawakawa swamp within Te Papakura o Taranaki 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 in the Stony catchment, although subject to short-term impacts due to erosion events at the mountain.

There is an estimates 83% of the stream banks in the catchment are planted in riparian vegetation with 72% stream banks located within Te Papakura o Taranaki and 11% of stream banks covered by a Council riparian management plan outside the National Park boundary. Further to this, 72% of stream banks are protected by riparian fencing within the National Park while a further 20% of stream banks are fenced outside the National Park.
