Ahuriri Conservation Park, Conservation park in Otago and Canterbury Regions, New Zealand

Ahuriri Conservation Park covers 49,000 hectares around the headwaters of the Ahuriri River, west of Lake Ōhau. The river separates the Huxley Range from the Barrier Range, and Mount Huxley, at 2,505 m, marks the northern boundary. The park runs 36 km north to south and is 22 km wide at its broadest point.

The park was created in March 2005 after the Nature Heritage Fund bought the Birchwood Station leasehold for NZ$10 million in 2004. Farming continued on the lease until 2010, and the council stopped maintaining the homestead road in 2011. In 2014 ecologist Peter Espie reported a decline in native plant species and suggested grazing management.

The park is named after Tu Ahuriri, a Ngāi Tahu chief. Māori used the Ahuriri River valley as a route to the West Coast to collect pounamu, greenstone. Trampers today follow the same valley on the Ahuriri Valley tracks.

The park is reached from Omarama, the nearest service town, and the road to the former Birchwood Station homestead has not been regularly maintained by Waitaki District Council since 2011. A high-clearance 4WD is needed beyond Ben Avon Ponds. Dogs must be kept on a leash, and mountain weather changes quickly.

Parts of the 2020 Disney film Mulan were shot in the Ahuriri Valley beside the park, including the training camp scenes and some battle scenes. The park also lies near the Aoraki Mackenzie International Dark Sky Reserve, and both the park and neighbouring Ben Avon Station are used for astronomy.
