We own a home on the Heretaunga Plains in Hawke's Bay and have school-age children. Flood risk, insurance and the cost of protecting our home are major concerns for us. I am considering my vote in the 2026 New Zealand general election. How would parties share the cost of flood protection between central government, councils and affected homeowners, and what are the trade-offs for our family?
Your question goes to the heart of a difficult policy choice facing flood-prone communities: who should pay for reducing risk when the benefits are local but the causes and consequences (extreme weather, insurance markets, national infrastructure resilience) are broader? I can compare the main approaches parties are likely to debate, but I can’t tell you how to vote.
For a homeowner on the Heretaunga Plains, the practical issues are likely to be:
- how much you pay through rates
- whether you face targeted flood-protection charges
- whether central government helps fund major infrastructure
- whether homeowners are expected to pay privately for adaptation (raising floors, drainage, insurance excesses, resilience upgrades)
- whether rules restrict future development or affect property values
Hawke’s Bay provides a useful real-world example. After Cyclone Gabrielle, central government and councils agreed a package involving government and council contributions for flood mitigation, infrastructure repairs, and Category 3 property buyouts. One agreement included a 50/50 government–council split for eligible buyout costs after insurance proceeds were taken into account, while flood protection funding was also shared.

The main cost-sharing models parties could choose between
1. Greater central government contribution
How it works
- The Crown pays a larger share of major stopbanks, river management, and resilience infrastructure.
- Funding comes from general taxation rather than only from affected regions.
Argument for this approach
- Flood protection can protect nationally important assets: housing, roads, food production, regional economies, and supply chains.
- A small rural or regional rating base may struggle to fund very large projects.
- Climate-related risks are not created only by local decisions.
Trade-offs for your family
- Lower immediate pressure on Hawke’s Bay rates.
- Less risk that a local council has to choose between flood works and other services.
- But taxpayers elsewhere contribute, including people who may not directly benefit.
- National funding can come with stronger government conditions on planning, building standards, or where rebuilding is allowed.
2. Councils and local ratepayers pay more
How it works
- Regional and district councils fund more through rates, targeted rates, and borrowing.
New Zealand’s flood protection system already commonly uses council funding, including rates and debt, sometimes alongside central government contributions. Part 2: The flood protection system — The Audit Office
Argument for this approach
- People who benefit most from a flood scheme contribute most.
- Local communities can decide their own priorities.
- It may encourage careful decisions about where and how development occurs.
Trade-offs for your family
- You may face higher rates, particularly if your property is considered to receive a direct benefit.
- Homes in protected areas may carry more of the cost even if the flood risk came from wider catchment issues.
- Councils may face pressure to spread costs over decades through debt.
3. More homeowner responsibility
How it works
- Owners pay more for property-level protection: flood barriers, raising homes, drainage improvements, insurance excesses, or accepting higher premiums.
- Government support may be limited to extreme cases.
Argument for this approach
- Owners make decisions about their own properties and receive the direct benefit.
- It may reduce incentives to build or remain in very high-risk locations.
Trade-offs for your family
- Costs fall unevenly: a household with a mortgage, children, and limited spare income may struggle to fund resilience upgrades.
- Insurance availability and affordability become major concerns.
- Individual measures cannot replace large-scale stopbanks or river management.
Where major parties’ philosophies generally differ
(Exact 2026 manifestos may not yet fully set out flood-costing details, so these are broad policy tendencies rather than promises.)
| Approach | More likely appeal to | Main concern |
|---|---|---|
| Larger Crown role | Those who see flood resilience as national infrastructure | Higher public spending and national taxpayer exposure |
| Stronger local funding responsibility | Those who favour local accountability and user-pays principles | Higher regional rates and uneven impacts |
| More homeowner responsibility | Those concerned about development incentives and private risk | Affordability and insurance gaps |
| Stronger planning restrictions | Those prioritising avoiding future exposure | Potential effects on property choices and values |
Questions you may want to ask candidates
For a Heretaunga Plains household, useful questions are very specific:
“If another major flood protection upgrade is needed, what proportion should be paid by central government, and what proportion by Hawke’s Bay ratepayers?”
“Should homeowners behind stopbanks pay a targeted rate, and if so how should ability to pay be considered?”
“What is your policy if insurance becomes unavailable or unaffordable in flood-prone areas?”
“Should government fund protection indefinitely, or should some areas eventually transition to managed retreat?”
“How will flood protection decisions affect schools, roads, hospitals, and the regional economy—not just individual properties?”
A family-focused way to compare policies
You might weigh each party’s position against four things:
- Household affordability now: rates, taxes, insurance, mortgage pressure.
- Long-term security: whether your children can safely remain in the community.
- Fairness: whether costs are paid by local beneficiaries, all taxpayers, or individual owners.
- Certainty: whether there is a clear plan for future floods rather than repeated emergency decisions.
The Heretaunga Plains case is particularly complex because it combines valuable agricultural land, towns and infrastructure, engineered flood defences, and exposure to major river events.
