The Orari River flows from the inland ranges of South Canterbury through Geraldine and reaches the coast near Orari township. It supports populations of brown trout in its accessible reaches and sees an occasional Chinook salmon run at the mouth during autumn. A distinctive feature is that sections of the middle river can lose surface flow to the gravel bed during dry summer periods. A Fish & Game Central South Island freshwater licence is required for angling.

About the Fishery
The Orari River is noted primarily for brown trout fishing in the lower reaches below Rolleston Road, with some rainbow trout also present in upper sections. The river offers opportunities for sight fishing in clear conditions where fish can be spotted in pools and runs. Flow varies significantly with season and rainfall, affecting the fishable length.
The middle reaches are prone to losing surface flow through the gravel and limestone bed during dry periods, with the riverbed reported dry for stretches of up to 13 km in low-flow years. Anglers should check current river conditions before planning a trip in summer.
A small or occasional run of Chinook salmon enters the river mouth in autumn, typically from March to May. The run is modest compared with larger regional fisheries, but fish can be targeted from the estuary and lower river when conditions allow.
Access and Regulations
The SH79 bridge near Geraldine provides straightforward access to the upper river, while the SH1 bridge at Orari opens the lower sections and estuary. Secondary roads offer additional entry points along the length. Always obtain landowner permission where required on private land and observe all Fish & Game regulations for the Central South Island region.
