Kaituna River re-diversion and Maketu Estuary enhancement project
Image above shows overview of planned work to re-divert Kaituna River and enhance Te Awa o Ngatoroirangi/Maketu Estuary.
Goal of this project:
To significantly increase the volume of water (particularly fresh water) flowing from the Kaituna River into Te Awa o Ngatoroirangi/Maketu Estuary, 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 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 resource consents and conditions for the project were finalised in an Environment Court decision issued in May 2016. All of the land acquisitions and detailed designs for the project have now been completed. See a map of publicly owned land around the estuary.
On 29 March 2018, Regional Councillors awarded a contract for construction works to J Swap Contractors Limited. Construction work will start in June 2018. Iwi, stakeholder and public meetings were held in May 2018, to introduce the contractors and outline the process and timeframes for the work before it starts.
A public site blessing was held on Tuesday 12 June, to mark the start of construction works for the project, see video below. Read about the event here>>
Public planting days are being held on Papahikahawai Island on 24 June, 1 July and 15 July, see details here>>

Consent and environmental monitoring
Monitoring programmes are in place to check that construction work meets resource consent conditions, measure the environmental benefits achieved through this project, and detect any unexpected environmental or cultural impacts.
Work completed to date
Creation of additional wetlands upstream in the Lower Kaituna Wildlife Management Reserve through Te Pourepo o Kaituna wetland creation project began in 2017 and is ongoing. This work will also provide a sand source for new stop banks associated with the Kaituna River re-diversion.
Complementary work on Papahikahawai Island was completed in 2017 as shown below. Restoration work and planting on the island is ongoing; community volunteers and contractors will plant another 15,000 plants on the island this winter.
This video shows a before and after comparison of the Papahikahawai lagoon, following the removal of the two causeways that were preventing tidal flushing of the estuary.
