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. Which Hawke's Bay flood-protection works are already funded or underway, and which are still future options or election promises? Who is responsible for delivering each?
Hawke’s Bay flood protection: what is funded, what is being built, and what remains undecided?
New Zealand general election: 7 November 2026 · Information checked to 16 October 2026
For a homeowner on the Heretaunga Plains with school-age children, the key distinction is between work that already has committed funding and a delivery programme, and longer-term proposals that could change the level of protection your home receives.
The important finding is that Hawke’s Bay already has a substantial, government-and-council-funded flood-protection programme underway. But the bigger question of how the region should protect the Heretaunga Plains over coming decades is still being considered. Those are two different things, and a promise to improve long-term resilience is not the same as funding a particular stopbank or drainage project.

1. The major funding already committed
North Island Weather Event (NIWE) flood-resilience programme
$256.5 million
Central government
$209 million
About 81%
Hawke’s Bay Regional Council (HBRC)
$47.5 million
About 19%
Programme funding for multiple flood-resilience projects across Hawke’s Bay, not a single project or a dedicated allocation for every home on the Heretaunga Plains.
The programme covers new flood defences, upgrades to existing stopbanks, pump stations and improved river-level and rainfall monitoring. HBRC is responsible for delivering most of these projects, with Hastings District Council delivering the Havelock North project. Wairoa has a separate $70 million Crown-funded allocation within the wider programme arrangements described by HBRC.

2. Projects already funded or underway
These are the main projects to distinguish from future proposals. The status below reflects HBRC’s project updates available in October 2026.
Complete
Waiohiki stopbank
A new 1 km stopbank and stream realignment have been completed. The scheme is designed to manage a flood with a 1% annual exceedance probability (AEP), rather than to guarantee protection against a Cyclone Gabrielle-scale event.
Responsible: HBRC, with central-government co-funding.
Source: Waiohiki project update. Waiohiki
Under construction
Pākōwhai flood defences
An 8.5 km flood-resilience network involving stronger existing stopbanks, new stopbanks and flood walls, and stream realignment. Earthworks were underway in multiple sections in August 2026. Forecast completion is in the second quarter of 2027.
Responsible: HBRC, with central-government co-funding.
Source: Pākōwhai project updates. Pākōwhai
Main works complete
Ōhiti Road | Ōmāhu local protection
About 2.1 km of stopbanks and bunds, road raising, drainage upgrades and erosion protection have been built to reduce flood risk around 11 previously high-risk properties. Final checks and reinstatement remained after main construction.
Responsible: HBRC, through the NIWE programme.

Near completion
Whirinaki
Residential and industrial stopbanks, drainage improvements and a raised section of State Highway 2. In August, HBRC reported the beach-side stopbanks were about 90% complete, with remaining works and road resealing scheduled around September–November 2026.
Responsible: HBRC, working with contractors including Fulton Hogan.

Under construction
Pōrangahau
A 1.7 km system of stopbanks and flood walls, built in stages on both sides of the river. HBRC reported construction progressing across all five sections in July 2026. The project is intended to reduce risk for 79 properties.
Responsible: HBRC; Galbraith Earthmovers is the main contractor for the northern works.
Source: Pōrangahau project updates. Pōrangahau
Enabling works underway
Ōmāhu Upper and Lower stopbanks
Approximately 2.8 km of stopbank along the Ngaruroro River is being upgraded and strengthened, with an additional 700 mm of freeboard incorporated into the design. Enabling works began in September 2026; the main construction phase was expected to finish around Christmas.
Responsible: HBRC; Galbraith Earthmovers is the main construction contractor.

Enabling works underway
Brookfields Lower stopbank, Awatoto
A 3.6 km stopbank upgrade along the Tūtaekurī River to address weaknesses identified in post-Cyclone Gabrielle flood modelling. Vegetation removal and site preparation began in September 2026, with main construction expected from October 2026 to April 2027.
Responsible: HBRC; Goodmans is the construction contractor.

Other funded works to know about
The programme also includes:
- Waipawa stopbank upgrade: an existing defence being upgraded to the updated regional standard.
- Pump station upgrades at Pākōwhai and Awatoto (Mission): designed to strengthen drainage and flood-management capacity.
- Regional telemetry upgrades: improved monitoring of rainfall and river levels to support earlier warnings and flood response.
- Havelock North flood resilience: delivered by Hastings District Council rather than HBRC.
- Wairoa flood mitigation: a separate major project with a $70 million Crown funding allocation.
These are all part of the wider funded programme, although their individual construction and completion milestones differ. The programme’s stated overall target is to have all construction works started by the end of 2026 and complete the programme by mid-2027.

3. What is still a future option, rather than a committed build?
This is arguably the most important distinction for someone deciding how to vote.
A. The long-term future of the Heretaunga Plains flood scheme
Not yet decided
HBRC’s Reimagining Flood Resilience project examined what flood protection should look like in the future following the Independent Flood Review after Cyclone Gabrielle. Community feedback and technical advice were presented to councillors on 29 July 2026.
The council has explicitly said that no decisions have yet been made on the future flood-protection options. These are to be developed and considered through its 2027–2037 Long Term Plan, with public consultation expected in 2027.
Responsible: HBRC, including decisions about future investment, scheme design and regional funding.

B. A higher or more comprehensive standard of protection
Investment decision pending
The major Heretaunga Plains and Upper Tukituki schemes have generally been designed around a 1% AEP flood standard, with an exception for Taradale, where the stopbank was raised to a 1-in-500-year level of service in 2022. HBRC is now considering what the schemes should look like and how they should perform in future.
Further stopbank raising, additional defences, catchment-wide measures or other interventions would need to be assessed, designed and funded. They should not be treated as approved construction projects merely because they are being considered.
Responsible: HBRC for regional scheme planning and investment; central government may have a role if additional national funding is proposed and approved.

C. The future cost to ratepayers
Not yet settled
The 2027–2037 Long Term Plan is the next major opportunity to determine which long-term options proceed, how much investment is justified and how the costs should be shared. The council has said the consultation will cover costs and trade-offs.
For your household, this matters because a future flood-protection project can be technically feasible without having its final funding package or rate impact approved.
Responsible: HBRC sets regional scheme and rating decisions through its formal planning processes. Central government determines whether any additional Crown contribution is made.

One legal detail is worth keeping in mind: the special Hawke’s Bay Flood Protection Works Order in Council provides a faster consenting pathway for specified recovery projects. It is not, by itself, a funding guarantee for every future flood-protection idea. Hawke's Bay flood protection worksSevere Weather Emergency Recovery (Hawke's Bay Flood Protection Works) Order 2024
4. What is an election promise, and who can actually deliver it?
As at 16 October 2026, I can verify the existing NIWE commitments and HBRC’s formal future-planning process. I have not established a sufficiently specific, independently verifiable set of 2026 party promises that names additional Heretaunga Plains flood-protection works, with amounts and delivery dates, to present a party-by-party comparison responsibly.
That distinction matters: a general promise to improve flood resilience does not establish that a particular stopbank, floodway, pump station or whole-scheme upgrade has funding approved.
Here is how to assess claims made during the campaign:
| What a candidate or party says | What to check |
|---|---|
| “We have funded flood protection.” | Is there a named project, a confirmed dollar amount and an identified Crown or council funding decision? |
| “We will build higher stopbanks.” | Which river or reach, what design standard, what engineering and consent work, and when? |
| “We will provide more central-government funding.” | Is this a costed policy commitment, a campaign announcement, or money already appropriated and contracted? |
| “We will protect homes from future floods.” | Does the policy explain residual risk, drainage, evacuation, maintenance and what happens in events beyond the design standard? |
| “We will make flood insurance more affordable.” | Is there a specific insurance or risk-sharing policy, or is the claimed benefit simply an expectation that lower risk may improve insurers’ decisions? |
Who has the power to act?
- Central government: can commit national funding, set legislation and national policy, and decide whether to support additional large-scale investment.
- Hawke’s Bay Regional Council: is the principal decision-maker for regional flood-control schemes, stopbanks, river management, pump stations, scheme investment and associated regional rates.
- Hastings District Council: has delivery responsibility for the Havelock North project and has its own responsibilities for local infrastructure and land-use planning.
- Insurers: make their own underwriting, excess, premium and coverage decisions. Completing a stopbank does not automatically oblige an insurer to lower a premium or offer cover.
For campaign-specific promises, the most useful comparison is between the official party policy, the candidate’s own statements and the relevant council’s published project and funding documents. A commitment should be described as an election promise until there is evidence that the necessary funding and delivery decisions have been made.
5. What this means for your home, insurance and household budget
There are three separate questions to keep in view.
- Does the work protect your property specifically?
A project nearby may strengthen one part of the river system without eliminating floodwater arriving from another direction or from surface-water drainage. Ask for the latest property-specific flood hazard assessment, including the modelled depth and extent of flooding with the completed works in place.
- Will it change your insurance?
Ask your insurer or broker in writing whether the completed project and updated hazard modelling would affect your premium, excess, flood exclusions or renewal terms. Do not assume a council’s improvement in flood-risk classification automatically changes an insurer’s assessment.
- Who pays for the work and ongoing maintenance?
Check the difference between the initial construction subsidy and the long-term cost of maintaining the scheme. For example, HBRC states that the Pōrangahau network’s expected operating and maintenance costs will be funded 70% through a targeted rate on local property owners and 30% through the general rate. That is a project-specific arrangement, not a universal rate split for the Heretaunga Plains. Pōrangahau
Also, a 1% AEP design standard is not a guarantee that a flood will occur only once every 100 years. It means there is a 1% chance of an event of that magnitude being exceeded in any given year. Larger events and other flooding mechanisms remain possible. WaiohikiAugust 2025
6. A practical checklist for your voting decision
Before the 7 November election, I would look for clear answers to these questions from candidates and parties, without assuming that any particular party’s proposal is preferable:
- Delivery: Will the existing $256.5 million programme be completed to its stated timetable and budget? Who will be accountable for delays or cost overruns?
- Long-term protection: What specific proposals do they support for the Heretaunga Plains scheme beyond the currently funded works?
- Funding: How much additional Crown funding, if any, is proposed? How much would be funded by regional or targeted rates, and over what period?
- Residual risk: Will proposals address surface-water flooding, drainage, river management and evacuation as well as stopbank height?
- Insurance and property risk: Will they support better property-level flood information and a clear process for communicating how completed works change assessed risk?
- Transparency: Will they publish costs, design standards, construction milestones and independent assessments of what the protection can and cannot achieve?
The key upcoming decision is HBRC’s 2027–2037 Long Term Plan. The 2026 election can affect the national government’s willingness to fund future works, but the longer-term regional scheme choices and rate implications still need to go through the council’s decision-making process.

- Ministry for the Environment — Hawke’s Bay flood-protection works and consenting framework
The bottom line is that substantial flood-protection construction is already funded and happening, but the future level of protection for the wider Heretaunga Plains—and how much households will ultimately pay for it—remains an open decision. For your family, it is worth separating evidence of completed and contracted work from promises about the next generation of flood defences.
