About the Ōpārara Basin
The Ōpārara Basin is one of the finest features of Kahurangi National Park. It is 20 kilometres north of Karamea in the Buller District on the West Coast.
The surrounding forest is a mixture of beech and podocarp trees, thickly carpeted with mosses and ferns.
Birds, insects, and fish flourish in the environment, which is home to the rare long-tailed bat, the giant land snail Powelliphanta, the Nelson cave spider, and whio/blue duck. The Ōpārara Basin is a great spotted kiwi sanctuary.
All insects, fossils, native birds and plant species are protected.
The Ōpārara Basin is a popular destination for visitors – 11,000 people visited in the 2017/18 year.
Facilities were improved in 2008 but wear-and-tear and increasing visitor numbers have meant that further upgrades are needed.
In 2018 the Ōpārara Valley Trust and Tourism West Coast sought funding from the Provincial Growth Fund for the Ōpārara (Arches) Project and received $5.7 million. The Prime Minister approved this funding in late 2018.
The project seeks to improve the visitor infrastructure at the Ōpārara Basin, with a focus on the deteriorating McCallums Mill Road and Ōpārara Arch Track.
Improving the facilities will make visiting the Ōpārara Basin safe and sustainable and will provide additional protection to the unique natural features.
The project also affirms Ngāti Waewae as guardians of the Ōpārara Basin.
The Department of Conservation leads this project, since all the components fall within the boundaries of the conservation estate, but DOC has partnered with the Ōpārara Valley Trust and Te Rūnanga o Ngāti Waewae who are kaitiaki of this rohe (area).
