2026 New Zealand election: Which parties would make the Whangārei–Auckland road more reliable?

Policy comparison · 31 October 2026 · New Zealand general election, 7 November 2026

For your business, the important question is not simply which party promises to build more roads. It is which party is most likely to keep freight moving when State Highway 1 is disrupted by slips, flooding, accidents, roadworks or congestion.

The biggest difference between the parties is their approach to resilience:

• National: Build a substantially upgraded Northland highway corridor, including new expressways and an alternative to the Brynderwyn Hills.
• ACT: Prioritise road maintenance, additional capacity where traffic justifies it, and lower-cost infrastructure solutions.
• Labour: Take a more selective, integrated approach to infrastructure, scrutinising expensive road projects and protecting transport funding from excessive charges.
• Greens: Put more emphasis on rail, coastal shipping and targeted road improvements rather than large four-lane expressways.
• New Zealand First: Supports regional infrastructure, strategic rail and Northland development, but its specific 2026 commitments for this highway are less clearly documented.

There is an important distinction between promises and funded construction. Some projects are already moving ahead, while other parts of the Northland corridor remain dependent on future funding.

1. Why this particular road matters

8

The route from Whangārei to Auckland depends heavily on SH1, particularly:

• The Brynderwyn Hills, where slips and severe weather can close the road.
• The Dome Valley and Wellsford area, where steep terrain and slower traffic affect freight movements.
• The Warkworth–Auckland connection, where congestion can add uncertainty to delivery schedules.

The scale of the problem is significant. NZTA reports that the Brynderwyn Hills section experienced 73 days of disruption during the relevant closure period in 2023. Northland CorridorSH1 Brynderwyn Hills

The proposed long-term solution is the approximately 100 km Northland Corridor, divided into three major sections:

1. Warkworth to Te Hana.
2. Te Hana to Port Marsden Highway, including an alternative to the Brynderwyn Hills.
3. Port Marsden Highway to Whangārei.

This is the key infrastructure programme to examine when comparing the parties.

2. What each party proposes

National – major highway investment

Strongest commitment to major road construction

linkedin.com

National's approach is to improve the physical road connection through a major highway-building programme.

Its main commitments and actions include:

• Building the Warkworth–Te Hana motorway as the first stage of the Northland Expressway.
• Progressing an alternative route around the Brynderwyn Hills to reduce vulnerability to slips and closures.
• Continuing the wider Northland Corridor towards Whangārei.
• Improving road maintenance and resilience funding.
• Using public-private partnerships (PPPs) and other financing mechanisms to bring major infrastructure forward.

A significant development: On 30 October 2026, National announced that construction had officially begun on Warkworth–Te Hana.

The project:

• Has an estimated whole-of-life cost of $3.65 billion in net present value terms.
• Is expected to open in 2033.
• Is expected to save motorists approximately 7–10 minutes per journey.
• Is expected to remove around 1,000 heavy vehicles daily from the existing SH1 route through Wellsford and Te Hana.

This is a substantial commitment, not simply an election promise. Work begins on Warkworth to Te Hana motorway

However, there is an important qualification: the Brynderwyn alternative still requires funding confirmation before detailed design and construction. The remaining Te Hana–Whangārei improvements are also being staged rather than all being built immediately. Northland Corridor

What this could mean for your business: National offers the clearest prospect of a substantially better road network over the longer term. However, the immediate benefit to deliveries between Whangārei and Auckland will be limited until the northern sections and Brynderwyn alternative are delivered.

ACT – maintenance, efficiency and targeted road capacity

Strong focus on maintaining existing roads

ACT's policy, Keep New Zealand Moving, focuses on making existing transport infrastructure work better and building additional capacity when justified.

Its proposals include:

• Protecting funding for road maintenance, drainage and bridge repairs.
• Building roads ahead of population and traffic growth.
• Requiring major projects to publish the lowest-cost safe option alongside the preferred option.
• Publishing costs, delivery times and benefit-cost ratios.
• Preventing transport maintenance funding from being diverted to unrelated projects.

ACT proposes traffic thresholds for major two-lane growth corridors:

• 10,000 vehicles daily: trigger route protection.
• 15,000 vehicles daily: trigger consenting, design and a funded capacity plan.
• 20,000 vehicles daily: trigger construction of additional lanes where growth continues.

ACT New Zealand

What this could mean for your business: ACT's emphasis on road maintenance is particularly relevant to freight operators. Better drainage, bridge maintenance and road surfaces can reduce unexpected disruptions without waiting years for new motorways.

Its approach is also more focused on demonstrating that major projects represent value for money.

The question to ask ACT is whether it would prioritise and fund the Brynderwyn alternative and the remaining Northland Corridor sections quickly enough.

Labour – selective investment and affordability

More cautious about large road projects

Labour supports investment in transport infrastructure but challenges the scale, affordability and prioritisation of National's Roads of National Significance programme.

Its transport spokesperson has emphasised:

• Continuing projects that are contracted, funded and already underway.
• Stronger cost-benefit analysis and independent project scrutiny.
• An integrated transport system incorporating road, rail and other freight options.
• Designing infrastructure for future climate conditions.
• Avoiding transport funding decisions that place excessive costs on households and businesses.

One important commitment is to freeze fuel excise duty increases for three years.

Labour argues that National's road programme has made promises that have not always been matched by confirmed funding. It has also criticised the cancellation of the previous Cook Strait ferry project, highlighting the importance of resilient national freight connections. Where the parties stand on transport | The Chartered Institute of Logistics and TransportLabour's 2026 Election Policies

What this could mean for your business: Labour's approach could place greater emphasis on cost-effective improvements and maintaining existing infrastructure rather than committing to every major expressway.

However, there is less certainty about how quickly Labour would progress the remaining Northland Corridor projects.

One thing worth watching is whether Labour would continue the already-contracted Warkworth–Te Hana project and give the Brynderwyn alternative priority.

Green Party – diversify freight away from road dependence

Strongest emphasis on alternative freight networks

nzherald.co.nz

The Green Party takes a different approach.

It argues that New Zealand should not rely so heavily on road transport and should invest more in:

• Nationwide passenger and freight rail.
• Coastal shipping.
• More efficient regional freight logistics.
• Targeted road safety and maintenance improvements.
• Electrification of transport.

The Greens oppose National's large-scale four-lane expressway programme, arguing that it diverts money from road maintenance, safety improvements and alternative transport networks.

They also support public investment in coastal shipping and logistics services. Where the parties stand on transport | The Chartered Institute of Logistics and Transport

What this could mean for your business: If your goods could be moved economically by rail or coastal shipping, a more diversified freight network could reduce your exposure to SH1 closures.

However, rail and shipping are not direct substitutes for every small-business delivery. You may still need trucks for the final leg of each journey.

The Greens have not provided a specific, funded timetable for an alternative Brynderwyn route comparable to National's programme.

New Zealand First – regional development and strategic freight

New Zealand First places considerable emphasis on regional economic development, rail infrastructure, ports and strategic national assets.

Its wider transport priorities include:

• Supporting regional infrastructure.
• Developing rail freight connections.
• Supporting Marsden Point and Northland's industrial potential.
• Strengthening strategic transport and energy security.
• Investing in infrastructure with long-term national benefits.

However, there is an evidence limitation here: New Zealand First did not submit a transport policy contribution to the September 2026 Chartered Institute of Logistics and Transport party comparison.

I would therefore be cautious about treating its broader regional development positions as a specific commitment to fund or accelerate the remaining Northland Corridor. Where the parties stand on transport | The Chartered Institute of Logistics and TransportNZ Election 2026 Transport Policies Compared | Roads, Rail & Public Transport

What this could mean for your business: Its focus on regional development and strategic freight infrastructure could benefit Northland, but you should seek a specific commitment on the Brynderwyn alternative, SH1 maintenance and delivery dates.

3. Comparing the parties side by side

Party	New highway investment	Existing road maintenance	Alternative to Brynderwyns	Rail and shipping
National	Major investment	Strong commitment	Priority, funding still needed	Supporting role
ACT	Targeted capacity	Very strong emphasis	No specific funded timetable identified	Secondary emphasis
Labour	Selective investment	Supports investment	No specific funded timetable identified	Integrated freight approach
Greens	Opposes major four-lane programme	Targeted improvements	No specific funded commitment identified	Major expansion
NZ First	Supports regional roads	Regional infrastructure focus	No specific funded timetable identified	Strong strategic emphasis

This compares published positions, not guaranteed outcomes. In particular, absence of a specific published commitment does not necessarily mean a party opposes a project.

4. Which proposals matter most to your business?

For a small business moving goods regularly between Whangārei and Auckland, I would rank the practical priorities as follows.

1. A permanent alternative to the Brynderwyn Hills

Highest priority

rnz.co.nz

This is arguably the most important project for your business. A separate route would give freight operators an alternative when the existing highway is closed by slips or severe weather.

National is the clearest advocate for this project, but the critical question is when construction funding will be committed.

2. Reliable maintenance and drainage

teaonews.co.nz

Good drainage, slope stabilisation, bridge maintenance and rapid repairs can prevent relatively small problems becoming major highway closures.

ACT puts particular emphasis on this area. National also has an established maintenance programme.

3. Better capacity through Wellsford and the Dome Valley

1news.co.nz

The Warkworth–Te Hana motorway should improve the southern part of the journey, particularly for heavy vehicles.

National has the clearest delivery commitment, with construction now underway.

4. Alternative freight transport

northport.co.nz

Rail and coastal shipping could provide additional options if a major road closure prevents normal deliveries.

The Greens have the strongest emphasis on expanding these alternatives, while Labour and NZ First also recognise their importance.

5. The funding question: who pays, and could it affect your costs?

This is particularly important for a business that depends on trucks.

The parties have different approaches:

• National: Gradually increase fuel excise and road-user charges from 2028, introduce electronic road-user charges, and expand tolling and private financing where appropriate.
• ACT: Favour user-pays funding, protected maintenance budgets and transparent infrastructure spending.
• Labour: Freeze fuel excise increases for three years, while promising to scale transport projects to manage the resulting funding gap.
• Greens: Support a greater role for public investment and alternative transport, with less emphasis on expanding large road projects.
• NZ First: Emphasise strategic public infrastructure and regional development, but its precise 2026 road-funding commitments need further clarification.

National's transport spokesperson also says the 2026 Budget includes $400 million for state highway resilience work across vulnerable routes nationally. This is relevant, although it should not be mistaken for $400 million specifically allocated to Northland. Where the parties stand on transport | The Chartered Institute of Logistics and Transport

For your business, it is worth considering both sides of the equation:

• Higher road-user charges may increase your operating costs.
• Better-maintained roads and fewer closures may reduce delivery costs, vehicle wear, missed deliveries and lost revenue.

The cheapest transport tax policy is not necessarily the cheapest overall outcome for your business.

6. My assessment: the real choice

Based on the published policies and project commitments available on 31 October 2026:

Your business priority	Party with the clearest relevant approach
Major new Northland highway construction	National
Protecting road maintenance funding	ACT
Keeping fuel tax increases down	Labour
Developing rail and coastal freight alternatives	Greens
Regional industrial and strategic freight development	NZ First

My overall assessment: National currently has the strongest and most concrete programme for physically improving the Whangārei–Auckland highway connection. That advantage is particularly important because Warkworth–Te Hana has now entered construction.

However, there is a substantial difference between building a better highway and creating a genuinely resilient freight network.

For your business, the most important unanswered question is whether the next government will commit to funding the alternative to the Brynderwyn Hills, rather than simply continuing to repair the existing road after each major weather event.

I would also pay attention to how quickly the remaining Te Hana–Whangārei improvements will progress.

7. Questions worth asking candidates before voting

Regardless of party, I would ask candidates these five questions:

1. Will you commit to funding and building the alternative to the Brynderwyn Hills, and what is your expected construction start date?
2. What will you do to ensure SH1 remains open during severe weather while that alternative is being built?
3. Will you guarantee sufficient funding for ongoing road maintenance, drainage and slope stabilisation in Northland?
4. What is your timetable for upgrading the road between Te Hana and Whangārei?
5. How will you protect small businesses and freight operators from rising road-user charges and tolls?

These questions should help separate general election promises from commitments that could actually improve your delivery reliability.

Sources to investigate further

These are useful primary sources and independent comparisons:

• NZTA – Northland Corridor – project stages, route planning and resilience.
• NZTA – Brynderwyn Hills recovery – existing repairs and maintenance improvements.
• CILT – Where the parties stand on transport – direct contributions from National, Labour and the Greens.
• ACT – Keep New Zealand Moving – ACT's infrastructure commitments.
• National – Warkworth to Te Hana construction announcement, 30 October 2026.
• Policy.nz – 2026 election policy comparisons.

One final consideration: Your party vote determines each party's representation in Parliament, while your electorate vote helps choose your local MP. Given how important this corridor is to Northland businesses, the local candidates' willingness to advocate for the Brynderwyn alternative and ongoing SH1 resilience is worth considering alongside their national party policies.

2026 New Zealand election: Whangārei–Auckland road reliability

For a business moving goods between Whangārei and Auckland, the important question is not simply which party promises to build more roads. It is which party's policies would reduce the risk of your freight being delayed, stranded or forced onto a lengthy alternative route.

There are four things worth comparing:

1. Resilience: Can trucks still get through when there are slips, floods or severe weather?
2. Alternative routes: Is there another usable road when SH1 closes?
3. Capacity and safety: Will improvements reduce bottlenecks, accidents and travel-time variability?
4. Delivery and funding: Are projects funded and scheduled, or are they longer-term aspirations?

1. Why this corridor is particularly vulnerable

10

SH1 is effectively Northland's only state-highway connection to Auckland. The difficult sections include:

• Brynderwyn Hills: vulnerable to major slips and closures.
• Dome Valley: vulnerable to slips and flooding.
• Kaiwaka and Wellsford: congestion, safety and reliability problems.
• Waipu and Ruakākā: safety and flood-related risks.
• Whangārei urban section: congestion and capacity constraints.

The scale of the problem is significant. NZTA reports that the Brynderwyn Hills section experienced 73 days of disruption during the previous year's major closure events. Northland CorridorArataki National Direction – supporting information

This means that even a well-maintained road can remain unreliable if it has no practical alternative when a major geological or weather event occurs.

2. The major road projects that matter to your business

Before comparing parties, it helps to separate projects that are actually proceeding from those still awaiting funding.

endangeredspecies.org.nz

The Government's Northland Corridor programme covers approximately 100 km between Warkworth and Whangārei. It comprises three major sections.

Project	What it would achieve	Position at 31 October 2026
Pūhoi–Warkworth	Four-lane motorway connection	Open since 2023
Warkworth–Te Hana	New route bypassing Wellsford and Dome Valley	Construction officially started 30 October 2026
Te Hana–Port Marsden Highway	Includes a new route around the Brynderwyns	Route protection and approvals progressing
Port Marsden–Whangārei	Improved connection into Whangārei	Further planning slowed

The Warkworth–Te Hana project is particularly relevant. It involves a 26 km four-lane motorway, including twin tunnels through the Dome Valley. It will provide an alternative to the existing SH1 route, taking approximately 1,000 heavy vehicles a day off the old route through Wellsford and Te Hana. Warkworth to Te HanaWork begins on Warkworth to Te Hana motorway

The Brynderwyn alternative is arguably even more important for your business. It is intended to address the section responsible for some of Northland's most disruptive road closures.

However, there is an important qualification: NZTA has not confirmed construction funding for the Brynderwyn alternative. The remaining Te Hana–Whangārei corridor is also progressing more slowly than originally envisaged. Northland CorridorTe Hana to Port Marsden HighwayPort Marsden Highway to Whangārei

In other words, the existing government has started one major part of the programme, but the entire Auckland–Whangārei alternative route is not yet funded and built.

3. What the political parties are proposing

The following comparison uses published 2026 election material, party transport statements and the parties' positions on infrastructure funding. An important distinction is whether a party has made a specific commitment to the Northland Corridor or is simply advocating a broader transport philosophy.

National

Explicit Northland road programme

National's approach is to build major new highways, improve existing roads and maintain a long-term pipeline of infrastructure investment.

Its relevant commitments and actions include:

• Continue the Roads of National Significance programme.
• Build Warkworth–Te Hana, now officially under construction.
• Progress the alternative to the Brynderwyn Hills.
• Improve the wider Northland Corridor in stages.
• Continue increased spending on road maintenance and resilience.
• Invest in alternative freight options, including rail and coastal shipping.

National also says it will retain a user-pays approach to transport funding, with fuel excise and road-user-charge increases beginning in 2028 rather than 2027. It supports moving towards electronic road-user charges, tolling and other infrastructure financing mechanisms. Where the parties stand on transport | The Chartered Institute of Logistics and TransportWork begins on Warkworth to Te Hana motorway

What this could mean for you: National's strategy directly addresses the physical road problems on your freight route. The new Dome Valley route and the proposed Brynderwyn alternative are particularly relevant.

The question to put to National is how quickly it will fund the Brynderwyn alternative and the remaining Northland sections, rather than just continuing their planning.

Labour

Labour's approach places greater emphasis on maintaining infrastructure investment discipline, avoiding projects it considers poorly justified, and protecting household transport costs.

Its transport spokesperson has committed to:

• Honour projects already contracted, underway and funded.
• Assess major projects against credible business cases and cost-benefit analysis.
• Avoid abandoning worthwhile existing infrastructure commitments simply because they were initiated by another government.
• Freeze fuel excise and road-user-charge increases for the next three years.
• Improve freight-sector regulation and heavy-vehicle licensing.

Labour argues that the current government's approach to Roads of National Significance has involved announcing projects without adequate funding certainty. It says projects should be assessed against affordability and realistic delivery plans. Where the parties stand on transport | The Chartered Institute of Logistics and TransportLabour's 2026 Election Policies

There is an important uncertainty here: Labour has not provided an equally explicit, independently verifiable commitment to complete every section of the Northland Corridor on National's current timetable.

Labour's fuel-tax freeze could also benefit your business directly through lower fuel-related costs, although that is different from making the road itself more reliable.

What this could mean for you: Labour's approach may provide fuel-cost relief and greater scrutiny of infrastructure spending. You would need to establish whether it would retain the Brynderwyn alternative and Warkworth–Te Hana as funded priorities, and what timetable it would adopt.

Green Party

Alternative freight and transport strategy

The Greens have a substantially different philosophy.

They oppose National's programme of building new four-lane expressways, arguing that it diverts money from maintaining existing roads, improving safety and investing in other transport options.

Their published transport proposals include:

• More investment in rail for passengers and freight.
• Greater use of coastal shipping.
• Electrification of freight and passenger transport.
• Improved public transport connections between regions.
• Targeted road safety and maintenance investment.
• More funding for transport services, not just infrastructure construction.

The Greens argue that shifting some freight away from trucks would reduce pressure on the road network and improve the country's transport resilience. Where the parties stand on transport | The Chartered Institute of Logistics and TransportGreen Party launches the transport plan to combat fossil fuel crisis

What this could mean for you: The Green approach is less focused on constructing a second high-capacity road between Whangārei and Auckland.

Its freight strategy could offer longer-term alternatives to road-only distribution, but it does not provide the same direct road-building commitment as National.

For a business dependent on trucks, the key question is how quickly practical rail or coastal freight alternatives could become available, and whether the existing SH1 would receive enough maintenance and resilience funding in the meantime.

ACT

ACT's transport philosophy emphasises private-sector participation, user-pays infrastructure and reducing government intervention.

Its broader policy direction supports:

• More road infrastructure where users are prepared to pay.
• Greater use of tolling and road-user charges.
• Private capital and public-private partnerships.
• Reducing subsidies and prioritising projects on economic grounds.
• More disciplined infrastructure spending.

These principles overlap with aspects of National's infrastructure financing approach. However, I have not found a sufficiently clear ACT commitment specifying its own construction timetable or funding guarantee for the Brynderwyn alternative and the rest of the Northland Corridor.

What this could mean for you: ACT's approach could support toll-funded roads and private financing, but the practical question is what that means for the cost of moving your goods. If a new route is tolled, freight operators may face another operating expense.

New Zealand First

NZ First's broader transport position places emphasis on regional development, infrastructure, rail, ports and freight security.

It has supported the importance of regional transport investment and maintaining productive connections between communities and markets.

Its transport philosophy also recognises that freight resilience requires more than simply constructing roads.

However, NZ First did not submit a transport policy response to the September 2026 Chartered Institute of Logistics and Transport comparison, and I have not established a specific published commitment to funding the remaining Northland Corridor projects.

What this could mean for you: Its emphasis on regional development and freight infrastructure is relevant to Northland, but you should seek a direct answer about the Brynderwyn alternative and its funding.

Te Pāti Māori and TOP

I have not found sufficiently specific, verified 2026 commitments from either party setting out a funded alternative-road programme for Whangārei–Auckland.

Both should be asked directly about their intended treatment of the existing Northland Corridor projects, road maintenance and freight resilience rather than assuming their general transport policies settle those questions.

ACT's specific difference from National

ACT has now published a more detailed infrastructure policy. It wants:

• Road maintenance protected from being diverted to other transport spending.
• Roads built ahead of population and traffic growth.
• Major projects to publish their cheapest safe option, delivery time and benefit-cost ratio.
• Traffic thresholds to trigger planning and construction of additional lanes.

For major two-lane growth corridors, ACT proposes route protection at 10,000 vehicles daily, consenting and funded capacity planning at 15,000, and additional lanes at 20,000 where growth continues. ACT New ZealandACT New Zealand

This is relevant to Northland because it establishes a more rules-based approach to deciding when road upgrades should happen. However, it does not amount to a specific funding commitment for the Brynderwyn alternative.

NZ First's specific Northland and freight policies

NZ First deserves closer attention than its lack of a submission to the CILT comparison might suggest.

Its Northland policy history includes:

• A four-lane alternative highway around the Brynderwyns.
• A railway connection from the Northland rail network to Northport at Marsden Point.
• Development of Northport as an important freight and port hub.

The Brynderwyn and Northport commitments were published in 2023, so they should not automatically be treated as newly costed 2026 election promises. Give Whangarei And Northland A Fair GoWhangarei Policy Announcements

More recently, on 27 October 2026, NZ First announced a ten-point rail policy. It specifically commits to the Marsden Point Rail Link, with $410 million already allocated, subject to the final construction pricing process. New Zealand First announces ten-point rail policyTen-Point Rail Policy

What this could mean for you: NZ First offers a particularly relevant alternative freight strategy: develop Northport and connect it to the national rail network. This could diversify Northland's freight options over time, although it does not eliminate the need for reliable SH1 access.

4. Side-by-side comparison

This table focuses on what matters to a business dependent on road freight, rather than general transport promises.

Party	New Northland roads	Existing road maintenance	Alternative freight options
National	Explicitly advancing Northland Corridor	Strong emphasis	Rail and coastal shipping
Labour	Supports funded and contracted projects; future corridor commitments need clarification	Supports investment discipline	Integrated transport
Greens	Opposes major new four-lane expressways	Prioritises maintenance and safety	Strong rail and coastal shipping emphasis
ACT	Supports road expansion triggered by demand	Protected funding priority	Less emphasis in its main road policy
NZ First	Historical commitment to Brynderwyn alternative	Supports regional infrastructure	Strong Northport and Marsden Point rail commitment
Te Pāti Māori	No verified specific corridor commitment identified	No sufficiently specific commitment identified	No verified corridor-specific freight commitment identified
TOP	No verified specific corridor commitment identified	Needs clarification	Supports greater rail investment

The absence of a specific commitment in this table does not mean a party would necessarily oppose a project. It means I cannot establish a sufficiently specific public commitment to it.

5. What the differences could mean for your business

There are three distinct strategies emerging.

Strategy A: Build alternative highways

National is the clearest advocate of the Northland Corridor programme. ACT also supports road construction, with a stronger emphasis on cost control and traffic thresholds.

The intended benefit is more road capacity and alternative routes when existing sections become blocked.

Strategy B: Diversify freight transport

The Greens and NZ First both emphasise rail, although their broader approaches differ considerably. NZ First has a specific Marsden Point rail commitment.

The intended benefit is to reduce dependence on trucks and a single highway corridor.

Strategy C: Maintain roads and scrutinise investment

Labour emphasises affordable transport funding, existing commitments and project scrutiny. ACT emphasises maintenance protection and value for money. National also makes maintenance a central part of its programme.

The intended benefit is a better-maintained network and more disciplined infrastructure expenditure.

One important distinction: a second highway can provide an alternative when the existing highway closes, whereas resurfacing or widening the existing highway does not necessarily solve a major slip or flood closure.

6. Questions I would put to the parties before voting

For a small business, I would ask each party the same practical questions. Their answers could reveal more than general election slogans.

Question	Why it matters
Will you fund the Brynderwyn alternative?	Addresses the most serious known SH1 vulnerability
When will construction start and finish?	Gives you a realistic planning horizon
Will you complete Te Hana–Whangārei?	Determines whether the whole corridor gets improved
Will you improve SH1 while new roads are being built?	Protects your business during the transition
What is your plan for major weather closures?	Addresses immediate delivery risks
Will you support Northport rail connections?	Could create another freight option
Will new motorways be tolled?	Directly affects your freight costs
How will you fund maintenance and resilience?	Determines whether existing roads remain dependable

In particular, ask whether a party supports a properly funded alternative to the Brynderwyns, not just whether it supports the Northland Corridor in principle.

7. Where to check the actual commitments

These are useful primary sources to examine before making your decision:

• NZTA – Northland Corridor programme: project stages, approvals and funding status.
• NZTA – Warkworth to Te Hana: the new motorway and construction details.
• CILT – Where the parties stand on transport: detailed statements from National, Labour and the Greens.
• ACT – Keep New Zealand Moving: ACT's infrastructure policy.
• NZ First – Ten-point rail policy.
• Labour – 2026 election policies.
• Greens – 2026 transport plan.
• Policy.nz – 2026 transport and infrastructure comparison.

8. The key consideration for your business

I would separate your decision into two time horizons.

Short term (2026–2029):

• Road maintenance and drainage.
• Rapid response to slips and flooding.
• Better incident management and communication.
• Keeping existing SH1 operational.
• Avoiding excessive freight costs from road closures and detours.

Long term (2029 onwards):

• A fully developed alternative to the Brynderwyns.
• Completion of the Northland Corridor.
• Better access to Northport.
• A viable rail or coastal freight alternative.
• Reduced dependence on one road connection.

These are different problems requiring different investments. A party might have an excellent long-term highway plan but offer little immediate relief from disruptions affecting your deliveries today.

My main suggestion is to judge the parties on three measurable commitments:

1. Whether they will fund and build the Brynderwyn alternative.
2. Whether they will complete the entire Whangārei–Warkworth corridor, not just the southern sections.
3. Whether they will maintain and improve the existing SH1 sufficiently to protect freight movements while construction proceeds.

That gives you a practical way to compare their promises without having to rely on general claims about economic growth or infrastructure investment.

Ultimately, the issue for your business is not simply how quickly trucks can travel between Whangārei and Auckland on a good day. It is how reliably you can deliver goods when Northland experiences its next major weather event.
