Kaituna River Re-diversion and Ongatoro/Maketu Estuary Enhancement Project

Background information:

Kaituna re-diversion plan overview as consented August 2015

Image above shows overview of planned work to re-divert Kaituna River and enhance Ongatoro/Maketu Estuary

Goal of this project:

To significantly increase the volume of water (particularly fresh water) flowing from the Kaituna River into Ongatoro/Maketu Estuary by 2018 in a way that maximises the ecological and cultural benefits (particularly wetlands and kaimoana) while limiting the economic cost and adverse environmental effects to acceptable levels.

The proposed re-diversion will maximise the flow into the Ongatoro/Maketu estuary while keeping Te Tumu cut open for flood protection and boating access.

The re-diversion will significantly change the existing landscape, particularly to low-lying land north of Ford’s Cut. It will also re-create at least 20 hectares of wetland habitat, partially restoring the landscape to what it looked like before 1956.

See the Project Background page for further information about the rationale and preparatory work behind this project. Base funding for the project was budgeted for in the Bay of Plenty Regional Council 2015-25 Long Term Plan which was adopted on 25 June 2015.

What's happening at the moment? 

All of the land acquisitions and detailed designs for the project have now been completed. See an updated map of publicly owned land around the Estuary.

Tenders for the main re-diversion construction works are underway. Construction is scheduled to start late summer/autumn 2018, subject to funding and contract negotiations. In the meantime, complimentary work on Papahikahawai Island has been completed in 2017 as below.
