Tongariro Riverflow

Water is utilised from rivers in the Tongariro, Whangaehu, Rangitikei and Whanganui catchments.

River flows can vary quickly and it is a good idea to check the weather forecast and assess flow conditions on the river before heading out. In some river systems, rainfall in headwater catchments will result in rapid increases in river levels downstream where there may be little rainfall.

Genesis Energy will be undertaking an upgrade of communications equipment on the Poutu Intake on the Tongariro River from 27 April to 1 May.

As part of the upgrade, the intake gates will be tested between 10pm (Sunday 30 April) and 2am (Monday 1 May). During this four hour period overnight the downstream river flows will rise and could fluctuate.

Flows will be higher in the Tongariro River below Poutu Intake during this time. Ring the Genesis Energy flow Phone on 07 386 8113 for flow information.

We have planned this work at night to minimise the effect on downstream river users and note that the work is subject to weather conditions allowing it to proceed.

Please be aware that the flows are subject to natural fluctuation (e.g. weather events) and generation flow changes. Please feel free to share this information with other river users (i.e. via website or social media pages).

If you have any questions or require further information, please contact Abbie Fowler on (07) 984 1130 or Abbie.Fowler@genesisenergy.co.nz.
