Background
You’ve likely heard of the proposal to dam the Kaituna River by now, but if not, this update provides a clear overview of the background, current status, and potential impacts of the project.
Taheke 8C, a Maori landowner group, is pushing for a dam below the trout pools that will drown Pari Whakahihi/Awesome Gorge (including the upper slalom training grounds), and dry Pari Tukino/Gnarly Gorge, before returning a highly variable flow back to Pari Kohukohu/Smokey Gorge. These sections are of immense recreational importance to both the local and international paddling communities. Their loss to this small-scale hydro scheme would be a devastating blow to the kayaking community.

Timeline of Events & Whitewater NZ’s Opposition:
May 27, 2024
Taheke 8C initially privately submitted for Fast-track Approvals consideration without consulting key stakeholder groups and was initially denied inclusion.
November 15, 2024
Taheke 8C proposes the project to Te Maru o Kaituna River Authority, and even at this stage, had still not managed to consult with any of the 5 River Iwi or other key stakeholder groups such as whitewater river users. In this meeting, they claimed they would consult with affected stakeholder groups like river iwi and river users. They have widely failed to follow through on this commitment.
December 18, 2024
Whitewater NZ shares information about the Taheke 8C dam proposal – this marks the first time many other stakeholder groups who value the river hear about this proposal.
December 23, 2024
Fast-track Approvals Act 2024 is passed by Parliament, confirming a new pathway for developments like this one.
February 7, 2025
New submissions under the Fast-track Approvals Act 2024 can begin, including previously declined “unlisted” projects such as Taheke 8C’s proposal.
March 14, 2025
Tapuika Iwi Authority presents unanimous opposition from all 5 river iwi to the scheme at the Te Maru o Kaituna River Authority meeting. This opposition is driven by a lack of respectful engagement and recognition from the consultants and concerns about cultural impacts, such as the negative effect of the dam on the Mauri of the Kaituna River (further insights here). Additional iwi and hapu groups with connections to the Kaituna/Ōkere awa have also illustrated opposition to the proposal.
April 17, 2025
Taheke 8C applies for the project to be reconsidered for referral under the Fast-Track Approvals Act. Again, they fail to meet their commitment to respectful, inclusive engagement, after a thinly veiled attempt at public engagement via a stakeholder meeting only two days prior on April 15, 2025!
May-June 2025 (estimated)
Fast track referral application review – a 100 working day process in which the MFE will review the referral application
July 2025 (estimated)
Minister decision on referral – The Minister for Infrastructure (Chris Bishop) will take the MFE review of the referral application and decide if it moves forward via Fast Track.
October 2025-February 2026 (estimated)
Fast track resource consent application process – if the referral application is successful, it is a 120 working day process, and the project becomes significantly harder to stop at this stage.
Current Focus: STOP THE REFERRAL
→ Whitewater NZ is working extremely hard to challenge the Fast Track referral application before it reaches the resource consent stage!
Why Whitewater NZ Opposes This Project
Recreational Losses
The lower gorges of the Kaituna/Ōkere River are a world-class whitewater kayaking destination and provide essential recreational opportunities for the local community and visitors alike. It is one of the best training grounds for slalom paddlers as well, and one of the few sections of class III, IV, and V whitewater paddling that is not subject to dam releases by resource consent agreements in the North Island.
Lack of Consultation
Despite promises, Taheke 8C has failed to properly consult with key stakeholders, including kayakers, river iwi, and downstream landowners. This ranges from an inability to answer simple questions, provide transparency in their plans, and general poor faith engagement. This consistently unacceptable behaviour gives little faith that they respect the shared value of the Kaituna/Ōkere awa ecosystem, or that they will provide sufficient mitigation if not challenged in the consent process.
Environmental Impacts
The proposed hydro scheme threatens the ecological integrity of the river system and the diverse wildlife that depends on it. Tuna (eels) and Kōura (crayfish) have used the Kaituna/Ōkere Awa as a traditional migratory route for thousands of years. A proposed residual flow below that of the required ecological minimum set by the Regional plan threatens the health of the awa. In addition, slowing the nutrient-rich waters of Lake Rotoiti can lead to increased algal bloom and periphyton (weed) growth above the dam.

Cultural Significance
The Kaituna/Ōkere Awa holds immense cultural importance for local iwi who have unanimously opposed this development. A summary of some of these important cultural considerations can be found in the Tapuika statement of position on the dam proposal.
Overstated Economic Impact
We believe the economic impact of the dam is vastly overstated. The numbers provided make it clear this is a micro hydro scheme, and will hardly contribute as a regionally or nationally significant renewable energy project by providing at best only 0.2% of NZ annual power requirements. The developers also consistently conflate the benefits of the dam with the envisioned “Taheke 8C Green Energy Hub” which includes a much larger, previously Fast-Track approved Geothermal project. This lends credence to the idea that the dam will have a negligible positive impact – the dam should be assessed on its own merits, and it’s clear the positives do not outweigh the negative impacts.
Our Approach
Whitewater NZ has been sharing information about the project as we’ve learned it via our social media channels. We’ve also been conducting a media campaign to inform the public and stakeholder groups on Taheke 8C’s secretive dam project – these press releases have put a spotlight on the dam project:
March 17: Kaituna River kayakers fight plans for hydro-electric scheme
March 20: Olympians hit back against Kaituna River plans
March 28: Possible Kaituna River dam project could have ‘catastrophic impacts’, board hears
April 18: Landowners renew fast-track bid for Kaituna hydro scheme

We have been and are continually working collaboratively with affected stakeholders, including iwi, downstream landowners, and environmental groups, to protect the Kaituna/Ōkere Awa through means both legal and otherwise.
At this stage, we are pursuing all possible avenues to challenge the Fast Track referral application, focusing on stopping this project before it advances to the resource consent application stage. We’ll provide updates on how these efforts are evolving in the coming days as the referral application is assessed by MFE and the Minister for Infrastructure – we’re hoping for a positive outcome given the widespread, unanimous opposition to the dam from many affected groups we’re working with.

A massive thanks to those who have already contributed their expert knowledge and helped out in our publicity campaign to raise awareness and combat the proposal! These contributions have been invaluable to our efforts to keep the Kaituna/Ōkere Awa free flowing and enjoyed by all.
