In the Far North of New Zealand, a tiny settlement is attempting something unprecedented. Whirinaki, a community of a few hundred people straddling State Highway 12 in South Hokianga, is planning a “managed retreat”—the relocation of an entire community to higher ground to escape the devastating cycle of repeated flooding.
While the concept of shifting towns out of harm’s way is becoming a frequent topic in climate change discussions, for the residents of Whirinaki, it’s a matter of survival. A severe flood on March 26 underscored the urgency, leaving 65 homes affected and nine completely uninhabitable. One home was later destroyed by a fire caused by floodwater infiltrating the electrical wiring.
The Human Cost of Recurrent Flooding
For many in Whirinaki, the March flood was a wake-up call regarding the speed and intensity of modern weather events. Bridget Wallace, who had returned home from heart surgery just one day before the storm, described a terrifyingly rapid onset.
“Within 12 minutes, everything was underwater. We just had time to get the vehicles out. Everything was floating. And I mean everything,” Wallace said. “I’ve lost everything. Everything that I owned.”
Others have tried to adapt in place. Christine Ryder’s mother lives in a home raised on stilts following the devastating 1999 flood, yet the March rains still surrounded the house within 20 minutes, trapping the family and destroying four cars and various equipment. Similarly, Shane Wikaira raised his home by two meters after the 1999 event, only to watch his property become an “island in a mud-coloured sea” during the most recent storm.
The Path to Managed Retreat
The decision to move is not a sudden one. Chantez Connor-Kingi of the Northland Regional Council noted that while the government previously provided funding via the National Infrastructure Fund for flood mitigation—including stopbanks, a spillway, and improved drainage—these measures were insufficient for Whirinaki. After reviewing detailed flood maps 18 months ago, the community concluded that managed retreat was the only viable answer.
Logistics and Land Acquisition
The project is hapū-led, managed by Storm Tautari and assisted by his sister, Ruth Tautari, chair of the Whirinaki Trust. The process began with a community search for suitable higher ground. Local whānau generously offered blocks of Māori land, though some were ruled out due to geological instability or prohibitive infrastructure costs.
Currently, two blocks of land have passed assessments, providing space for an initial 26 homes. A primary goal is to ensure the new sites remain close to the existing settlement to maintain the deep ancestral connection to the whenua (land).
The Financial Blueprint
The scale of the relocation is significant. A business case developed by the Whirinaki Trust and the planning firm The Urbanist outlines the following costs:
- Housing and Infrastructure: $60 million to relocate approximately 80 whānau.
- Economic Development: $26 million for initiatives aimed at reversing local deprivation.
The Trust expects approximately one-fifth of this funding to come from philanthropic foundations, with the remainder sought from the central government. Discussions are currently underway with the Ministry of Housing and Urban Development.
The Conflict: Ancestry vs. Adaptation
Despite the risks, the idea of leaving is polarizing. For some, the land is an inseparable part of their identity. Shane Wikaira noted that his family has been present since the time of Kupe, making the land “more than just land.” Bridget Wallace expressed similar sentiment, stating, “Our tūpuna [ancestors] didn’t run away from their land.”
However, for parents like Dwayne Rawiri, the priority is the safety of the next generation. Rawiri, who is currently moving a family cabin to higher ground before winter, believes relocation is the only solution for his eight children. “I think we’re just going to have a whole community busted to be honest, maraes and all,” Rawiri warned.
A National Precedent for Climate Adaptation
If successful, Whirinaki would be the first time an entire New Zealand community has relocated due to climate change. Climate Change Minister Simon Watts stated that the government remains committed to working with councils to determine the best path forward, emphasizing that decisions are best made at the local level through the National Adaptation Framework.
The urgency is echoed by the Climate Change Commission. CEO Jo Hendy recently warned that climate-driven severe weather is already causing “long-lasting hurt, grief and fear.” Hendy argued that the current policy framework has “extreme” shortfalls, noting that too much capital is spent on post-event recovery rather than proactive resilience and relocation.
Key Takeaways: Whirinaki Managed Retreat
- The Trigger: Repeated flooding, including a severe March event that left nine homes uninhabitable.
- The Plan: A hapū-led initiative to move 43 homes and roughly 260 people to higher ground.
- The Cost: An estimated $86 million total for housing, infrastructure, and economic development.
- The Challenge: Balancing the need for physical safety with the cultural imperative to remain on ancestral land.
- The Significance: Potential to be New Zealand’s first total community relocation due to climate change.
As the Whirinaki Trust continues its negotiations for funding, the settlement remains a testing ground for how indigenous communities and governments navigate the inevitable shift of populations away from increasingly volatile environments.
