He Pou a Rangi Climate Change Commission’s latest case study has found that climate change is already driving physical impacts across Te Taitokerau/Northland, disrupting infrastructure, affecting food systems, and placing additional pressure on communities that are already socially and economically stretched.
The report finds that residents, businesses, iwi, and hapū are dealing with more frequent and intense weather events, shifts in rainfall and temperature, and ongoing coastal and riverine hazards. These changes are described as influencing where people can live, how primary industries operate, and how reliable core services such as transport, power, and communications remain during adverse events.
Insights from the case study will feed into the second national climate change risk assessment and the commission’s second monitoring report on the government’s national adaptation plan, both scheduled for release in 2026. For insurers, the findings provide local detail alongside national climate projections and point to evolving risk profiles for personal, commercial, and rural portfolios. “For an inherently local issue like climate adaptation, we need to understand what is happening on the ground,” said Climate Change Commission chief executive Jo Hendy.
The report notes that people in Te Taitokerau did not describe climate change as a future concern. Instead, they reported changes that are already influencing daily life and business operations. “When we visited the region to hear how people, communities, and businesses are experiencing the growing pressures of a changing climate, the message we heard repeatedly was not concern that climate change is coming – it was that it’s happening now,” Hendy said.
Those consulted pointed to impacts across coastal and marine environments, rivers, whenua, and forests, with flow-on effects for kai systems, local economies, and community wellbeing. Storms and heavy rainfall were reported to disrupt roads, power lines, and telecommunications, reducing access to health care, education, workplaces, and supply chains, and limiting economic activity during and after events.
Supporting technical work cited in the case study indicates that Te Taitokerau is likely to face increased coastal inundation and erosion, more regular river flooding and sedimentation, longer dry spells, elevated fire danger, and changes in seasonal patterns such as frost and spring rainfall. These shifts are expected to influence land use decisions, local government services, and regional investment.
The commission records a range of adaptation initiatives emerging from communities, businesses, and Māori entities. These include:
Hendy said interviewees consistently linked these activities to local values and priorities. “People told us that responses that are founded on their community’s strengths and values allow them to focus on adapting in ways that help everyone to cope and build resilience,” she said.
At the same time, many participants said that scaling these efforts depended on national policy and funding settings. They identified needs for reliable access to information and data, long-term, and predictable policy and funding pathways, support to access capital, clearer allocation of roles and responsibilities across legislation and national plans, and investment in infrastructure “that would keep people connected and safe.”
The commission also heard preferences for approaches where communities can lead local adaptation decisions while aligning with broader objectives such as regional economic development and greater use of Māori leadership and knowledge.
From an insurance perspective, the case study describes sector-specific and infrastructure-related pressures that may influence risk selection, pricing, and claims. In horticulture, growers reported new pests and diseases, along with more variable rainfall and temperature patterns, affecting production systems. Adaptation measures cited include manual pollination where bees cannot fly in heavy rain, planting on raised mounds to lower surface flooding risk, and adoption of more disease-resistant rootstocks. Producers said rising costs and risks are increasing the need for capital to support adaptation investments.
In the pastoral sector, farmers described the combined impacts of higher temperatures and prolonged dry periods on pasture quality, and heavier rainfall contributing to pugging and erosion. The report notes a greater reliance on support networks such as Rural Support Trust Te Taitokerau and the launch of a Resilient Pastures pilot programme in the region.
Flood management is another focus area. Northland Regional Council’s climate resilience work includes long-running schemes such as flood protection on the Awanui River for Kaitāia, as well as more recent collaboration with communities to reduce risks for at‑risk marae. Flooding and declining river health are described as recurring concerns for transport, properties, and businesses, with downstream effects on coastal waters and marine resources.
Infrastructure operators are also adjusting. Top Energy, which distributes electricity in the Far North, is investing in remote network automation and localised generation, including geothermal. Golden Bay Cement is exploring rail as a transport option for diverted waste products it uses to replace a significant share of its coal consumption, with keeping operations running during disruptions among the considerations.
The case study references national analysis that places Northland high on several indicators of social vulnerability, including access to financial resources, reliable internet, and safe, uncrowded housing. These indicators can influence households’ ability to prepare for, withstand, and recover from climate-related events.
In Te Taitokerau, climate impacts were described as compounding existing pressures related to income, housing, and service access. Interviewees said that when roads, power, and communications fail in extreme weather, some communities can be cut off from supplies, health care, schools, and workplaces for extended periods. Hokianga community consultant Zonya Wherry said shared priorities across communities could be summed up simply. “It doesn't matter where we're from, we all actually want the same things: we want food security, water security, and a safe roof over our head,” Wherry said.
While the commission’s case study provides a qualitative, place-based view of local climate impacts and responses, Vero Insurance’s second Climate-Related Disclosures Report adds a portfolio-level, quantitative perspective on future physical risk. The report estimates that, without significant mitigation, average annual losses from extreme weather could increase by 19% to 26% by mid-century, driven largely by sea-level rise and more frequent surface water flooding. The South Island is identified as a region with heightened exposure under the modelled scenarios.
The insurer also finds that losses are likely to be concentrated in a small segment of the property portfolio. Less than 1.5% of insured coastal properties are expected to account for all projected coastal inundation losses, while under 2% of inland properties are linked to 30% of forecast flood-related losses.
