Recreational Releases and Flushing Flows

Genesis Energy's resource consents for the Waikaremoana Power Scheme require recreational flow releases from Piripaua Power Station and Tuai Power Station.

Assess the conditions for yourself before entering the river, and please ensure anyone using the river is aware of these flow changes.

Stop the spread of freshwater pests!

All equipment that has come from any other fresh waterway (regardless of island) must be decontaminated using approved methods (see CheckCleanDry) before entering the river.

Please do not rely on the ‘dry' method alone as the inside of kayaks take a very long time to dry out!

Cleaning solution is available at the entry and exit points during recreational releases.
