Key Takeaways
- Repeated flooding and bridge washouts have left South Wairarapa farmers, especially Rod Sutherland, feeling trapped and eager to sell their land.
- Community members blame inadequate river‑gravel management by the Greater Wellington Regional Council (GWRC) for exacerbating flood impacts.
- Local leaders, including Mayor Dame Fran Wilde, are urging central‑government support for infrastructure upgrades and a revised flood‑management strategy.
- GWRC acknowledges the need for a new approach, is reviewing its 50‑year‑old Lower Wairarapa Valley Development Scheme, and proposes collaborative solutions with mana whenua, farmers, and district councils.
Farmer Rod Sutherland’s Struggle
Rod Sutherland, a fifth‑generation farmer who has worked the Pirinoa land for over two decades, says the past year has been particularly brutalised the worst he has experienced. Back‑to‑back storms flooded his farm, submerging half the paddocks and destroying access roads. He described the situation as a “burden” and a “trap,” stating that he now wants to sell the property because the stress and financial strain have become untenable.
Repeated Bridge Washouts
The Tūranganui Bridge, a vital lifeline for residents south of the river, has washed out twice in four months. More than 450 homes were isolated after the latest failure on Saturday morning; they were only reconnected on Tuesday afternoon. Locals argue that the bridge’s repeated failures expose deeper problems with river management rather than merely isolated weather events.
Community Frustration Over River Management
Residents point to a perceived lack of river‑gravel extraction as the primary cause of the flooding. Farmer Ken Aburn noted that even though recent rainfall was less intense than February’s deluge, excess gravel in the Tūranganui River left water nowhere to go, leading to the bridge’s collapse. Nicola Warren of Lake Ferry described the situation as “destroying the rivers, the farms, and people’s hearts,” underscoring the emotional toll on the community.
Historical Context and Personal Reflections
Sutherland recalled his father’s warning: “That river will break your heart.” He said his father had advised him to sell up and move away, a suggestion he ignored at the time. Now, after 17 years without any gravel removal from his stretch of the Tauanui River, Sutherland observed that the riverbed has dropped three metres below the surrounding land, leaving him with no natural flood protection. He believes regular gravel extraction could have mitigated the damage from the recent storms.
Calls for Gravel Extraction and Long‑Term Solutions
The farmer advocates for immediate, increased gravel extraction across South Wairarapa’s waterways and proposes a long‑term strategy in which GWRC purchases land bordering the rivers solely for flood spillover. He argues that balancing environmental protection with the needs of rate‑payers is essential, and that the current scheme fails to protect those who pay the rates while preserving ecological values.
Mayor’s Appeal for Government Assistance
South Wairarapa Mayor Dame Fran Wilde told RNZ’s Rural News that she met with GWRC on Monday to discuss river management and plans to speak directly with farmers. Emphasising the region’s sparse population, she called on central government to fund new bridges and improve flood‑defence infrastructure, stating that the Wairarapa’s productive land contributes nationally important primary‑sector work that deserves broader support.
Greater Wellington Regional Council’s Response and Review
GWRC catchment manager for Ruamāhanga, Pete Huggins, confirmed that a thorough review of the more than 50‑year‑old Lower Wairarapa Valley Development Scheme is underway. The council is sharing flood‑hazard modelling with the community and discussing current service levels. Huggins noted that while about 3,000 cubic metres of gravel are removed annually upstream of the Tūranganui Bridge, commercial extraction is not economically viable without ratepayer funding.
Technical Insights on Flood Protection
Huggins explained that the intense 72‑hour rainfall likely overwhelmed any existing flood‑protection scheme, and that the design of the washed‑out bridge contributed to its failure—a low bridge can act as a dam, constraining flow even when the channel is clear. He agreed that maintaining the bridge as a lifeline is critical and suggested possible alterations to the river channel or bridge structure to improve resilience.
Path Forward and Collaborative Approach
The council intends to co‑design a sustainable catchment strategy with mana whenua, farmers reliant on the existing scheme, and the wider community. Ongoing work with the South Wairarapa District Council includes exploring options for gravel extraction, stockpiling, and managing extreme rainfall events at the Tūranganui Bridge. Huggins stressed that a new approach is needed—one that balances ecological stewardship with practical flood mitigation to safeguard both the environment and the livelihoods of South Wairarapa residents.
