The Wairaurāhiri River is a river in southern Fiordland, New Zealand, draining Lake Hauroko into the sea. Many boats have got into trouble along its length, as the river flows quite quickly with grade-3 rapids, so the main boats that use the river are commercial jetboats.[1] There is a 157m (515feet) drop from the source at Lake Hauroko to the mouth, which empties into Foveaux Strait.[2]
There is an active stoat and rat trapping program set up along the length of the river and maintained by locals.[3] Possums were plentiful in the area as early as 1900.[4]
