Te Kāuru Upper Ruamāhanga Floodplain Management Plan

River Road, Masterton erosion protection works

The River Road, Masterton project has evolved from the initial planning within the Floodplain Management Plan (see pages 78 and 79) to now include protection at the Masterton District Council closed landfill.  Initially the erosion protection was solely centred around the residential properties, however now the erosion protection covers not only the residential properties but also the cemetery and the Masterton District Council closed landfill.

The project at River Road, Masterton is being completed in three stages. Stage one is the construction of six rock groynes (rock boulders) to protect the Ruamāhanga River from the Masterton District Council closed landfill.  This work is currently underway and will be completed by 30 June 2023.

An estimated 3,000 plants are being procured for a planting programme at this project site. Rangitāne o Wairarapa will be involved in assisting with the planting activities.

Programme progress is being regularly communicated to partners and stakeholders (including iwi, Fish and Game, Department of Conservation, and Masterton District Council).

Stage two construction, which is a 150m rock revetment (wall) will commence in the summer of 2023 due to the consideration of winter months. The rock revetment is to protect a number of River Road residential properties and starts where the Waipoua and Ruamāhanga Rivers meet. Preparation for this work has begun with a finalised design being completed, followed by a construction contract in readiness for the summer start.

The third and final stage is to protect the cemetery from further erosion. At present the draft design is for 11 rock groynes.

Paierau Road – flood signage

Paierau Road can often be flooded by the Waipoua River in heavy rain events, therefore Te Kāura has addressed this issue by requiring the installation of permanent warning signs.  For more details on this project please see pages 122 and 123 of the Floodplain Management Plan.

Paierau Road flood signage project is slowly making progress. Signs have been ordered, however finding a contractor who has capacity to install the signs has not been easy. We are still working with Masterton District Council in the hope that the work can be completed within this financial year.

A rate change proposed in the Te Kāuru Flood Management Plan (FMP) (PDF 26 MB) was recently approved by council in two stages:

• 16 June 2022: New funding method approved
• 30 June 2022:  Annual Plan and rates resolution paper approved.

On 1 July 2022 the rates change came into effect.

This means a targeted rate now applies to all landowners in the catchment.

In the past this rate only applied to riverside land owners. This change was made because the December 2019 Te Kāuru FMP goes beyond river management to provided wider catchment and community benefits. So, it made sense that people who live across the catchment contributed to this.

Before being considered by council, this proposal went through a Revenue and Financing Policy Review. This review process involved holding a public hearing and consulting with the public on the proposed change.

The Upper Ruamahanga River Management Advisory Committee (URRMAC) has held several meetings and workshops to understand the Te Kāuru FMP.

The committee’s recent discussions focused on the Te Kāuru FMP’s vision of allowing the river more room. In the coming months, we will share information with the public and riverside landowners. 

During the COVID-19 alert levels, we worked to obtain funding from the government’s COVID-19 economic stimulus package. This includes funding of shovel ready projects through the Infrastructure Reference Group (IRG), the Ministry for the Environment (MfE), and other agencies. 

MfE Funding – Major Rivers – Riparian Management

A total of 17 funding applications were put forward to the MfE for a variety of environmental activities. The MfE selected two of these applications:

• Wairarapa Moana Wetlands Project 
• Major Rivers – Riparian Management

The Major Rivers – Riparian Management application to the MfE was based on the Te Kāuru Upper Ruamāhanga Floodplain Management Plan, specifically the riparian planting and fencing buffers.

This project will be spread over five years and cost $5 million. It aims to create 35 jobs with 120,000 trees (both willows and natives) to be planted over 100 hectares, with 30 kilometres of fencing. One of the main objectives will be to ensure healthy plant survival rates through pest animal and pest plant control.

Connecting with community and iwi groups is crucial to the success of the project, and we encourage anyone who has an interest in riparian planting to get in touch.

PDU/CIP Funding – River Road, Masterton

During the government’s COVID-19 alert levels 4 and 3, the Flood Protection department submitted applications to the Provisional Development Unit (PDU) for shovel-ready projects. The Provisional Development Unit is now called Kānoa - Regional Economic Development & Investment Unit. 

The successful application was for a number of Hutt Valley erosion edge protection sites, RiverLink (Lower Hutt) river works and Ruamāhanga River scheme River Road, Masterton edge protection works.

The proposed work for the River Road site is based on the Te Kāuru FMP major project response, with an extension of river-edge protection from River Road to (and including) the Masterton District Council’s closed landfill. The River Road projects will cost $2 million over two years, with Kānoa contributing 64% and we will provide the balance 36%.

We have signed agreements with our iwi partners to co-design and work together on this project. We are working on the geotechnical and initial design details.

Operational work programmes continue as they have in the past. 

River Management Group applications 

Earlier this year, we invited community members to apply to join any of the nine River Management Groups in Te Kāuru catchment. Applications closed on 15 March 2023. 

Applicants were contacted with the outcome of their application in early May 2023.  

The first River Management Group meeting will take place in July 2023. 

If you have any questions about this process, please contact Madeliene Playford via email at madeliene.playford@gw.govt.nz.

The Upper Ruamāhanga River Management Advisory Committee (URRMAC) welcomes Cliff Bouton, representing the Waipoua Urban reach. This appointment follows a nomination process held in late 2021. Find out who else is on URRMAC.

We’ve been meeting with URRMAC to discuss the principles of the Flood Management Plan, including what allowing the river more room means in practice. We find people often misunderstand this idea. So, from March to May 2022 we’ll develop a plan to help people understand this concept.
