Transporting Machinery Between Sites

What Machinery Transit Insurance Typically Covers

Cover varies between policies and insurers, but a well-structured plant transit policy generally addresses:

• Physical loss or damage to the machine while being loaded, transported, and unloaded
• Salvage and recovery costs when a machine needs to be winched, lifted, or recovered after an incident
• Debris removal and clean-up following a load failure or vehicle rollover
• Hazardous substance incidents where emergency services attend a spill involving your machine or its fluids
• General average liability for Cook Strait ferry crossings under maritime law
• Third-party liability arising from a transit incident on a public road

What's included depends on the specific policy wording and any extensions in place. Some of these items are standard inclusions. Others are optional extensions that need to be specifically arranged. That's why it pays to have a broker review the detail, not just the headline cover.

What Affects the Premium for Machinery Transit Insurance

Several factors influence what you'll pay for transit cover on your plant:

• Type and value of machinery: heavier, higher-value machines carry more risk and typically attract higher premiums
• Frequency of transit: how often machines are moved, and over what distances, affects the overall exposure
• Routes used: urban routes, remote roads, and Cook Strait crossings each carry different risk profiles
• Transport method: whether machines are moved on purpose-built floats, general trailers, or under their own power on public roads
• Claims history: previous transit incidents or plant claims will be factored into the premium
• Cover structure: the scope of extensions included (salvage, recovery, hazardous substance, general average) affects the overall premium

Every business is different. The best way to understand what you'll pay is to get a quote based on your specific operation.

When the Machine Leaves the Site, the Risk Doesn't

Most contractors think about insurance in terms of what happens on the job. The excavator breaks down. The digger damages a buried service. The skid steer tips on uneven ground. All real risks, all worth covering.

But here's what often gets overlooked: the journey between sites.

Loading a 20-tonne excavator onto a float, hauling it down State Highway 1, crossing the Cook Strait, and unloading it at the other end, every one of those steps carries genuine exposure. And not all plant policies treat transit the same way. Some cover it well. Others have gaps that only become obvious when you're standing on the side of the road watching your machine being winched out of a ditch.

This is what machinery transit insurance in NZ is actually about: making sure the cover follows the machine, not just the site.

What Can Go Wrong in Transit

It's easy to underestimate transit risk because moving a machine feels routine. You've done it dozens of times. But the exposure is real.

The Machine Comes Off the Float

It happens. A tie-down fails, a corner is taken too fast, the load shifts on a gravel road. When a machine comes off a float at speed, you're not just looking at damage to the machine itself. You're looking at road damage, potential injury, damage to other vehicles, and the cost of getting the machine recovered and transported to a repairer.

Salvage and recovery costs can be substantial, particularly for larger plant. Some plant policies include an extension that covers reasonable salvage, recovery, and re-siting costs when a claim is accepted, but the scope of that cover varies. Check whether yours does, and whether there's a cap that might leave you short on a large machine.

The Float Rolls

A fully loaded low-loader rolling on a bend is a serious incident. The machine is damaged. The float may be written off. There's debris across the road. And if the machine carries hydraulic fluid, diesel, or other substances, you may have a hazardous spill to deal with on top of everything else.

Some motor vehicle policies include specific cover for hazardous substance emergencies, the kind where Fire and Emergency New Zealand attends and is authorised to charge for their response. That's a real cost that can catch operators off guard. Worth checking whether your policy addresses it, and to what extent.

Debris and Clean-Up

When a load comes off or a vehicle rolls, the road doesn't clean itself. Debris removal and site clean-up costs can add up quickly, especially on a busy road where traffic management is involved. Not every policy treats these costs the same way. Some include them as part of the loss. Others treat them as a separate item with separate limits. Know which you're dealing with before something happens.

Crossing Cook Strait: General Average and Why It Matters

If you're moving plant between the North and South Islands, you're putting your machine on a ferry. And that introduces a concept most contractors have never heard of: general average.

General average is a principle of maritime law. In simple terms, if a vessel encounters an emergency and cargo has to be jettisoned or sacrificed to save the ship and the remaining cargo, all cargo owners share in the loss, proportionally. Even if your machine is sitting safely in the hold and nothing happens to it, you could still be required to contribute to the losses of other cargo owners.

It sounds obscure. It isn't. It's a real liability that arises from the contract of carriage and the governing law of maritime transport.

Some motor vehicle and plant policies include an extension that covers general average costs you're legally required to meet when your machine is in transit between places in New Zealand. If yours doesn't, and your machine crosses Cook Strait regularly, that's a gap worth closing.

Talk to your broker about whether this applies to your situation.

Oversize Loads and Pilot Vehicle Requirements

Moving large plant on public roads in New Zealand requires compliance with oversize load rules. Depending on the dimensions and weight of the load, you may need permits, pilot vehicles, and specific route approvals. These aren't optional, they're legal requirements.

From an insurance perspective, non-compliance matters. If you're moving an oversize load without the required permits or pilot vehicles and something goes wrong, your insurer may have grounds to decline or reduce your claim if the breach contributed to the loss. Policies typically require that the vehicle and load are operated in accordance with all applicable laws and regulations.

This isn't about catching people out. It's about making sure the way you operate matches the assumptions your policy is built on. If you're regularly moving large plant on public roads, it's worth having a conversation with your broker about how your policy responds, and whether there are any conditions you need to be aware of.

The Gap Between Plant Insurance and Transit Cover

Here's something worth understanding: a plant insurance policy and a transit policy aren't the same thing, and they don't always overlap cleanly.

A standard contractors' plant policy, the kind that covers your machinery on site, is primarily designed to cover the machine while it's working. Some policies extend naturally to cover transit between sites. Others have conditions or exclusions that limit cover during loading, transport, or unloading.

The question to ask is: what exactly does my policy cover when the machine is on the float?

• Is the machine covered for physical loss or damage during transit?
• Does cover apply during loading and unloading, or only while moving?
• Are salvage and recovery costs included if the machine needs to be winched off the road?
• Is there any cover for debris removal or clean-up costs?
• Does the policy address hazardous substance incidents?
• Is general average covered for Cook Strait crossings?

If you can't answer those questions with confidence, that's a sign the policy needs a closer look.

A Practical Checklist: Before You Move the Machine

Before your next float move, run through these:

• Confirm your plant policy covers transit: not just on-site operation
• Check how loading and unloading are treated: some policies have specific conditions around this
• Review salvage and recovery provisions: know whether these costs are included and whether there's a cap
• Understand your hazardous substance exposure: particularly relevant for machines carrying fuel or hydraulic fluid
• Check general average cover if crossing Cook Strait: this is a real maritime liability
• Ensure your oversize load permits are in order: non-compliance can affect a claim
• Confirm the float operator has appropriate insurance: their liability doesn't automatically protect your machine
• Know your excess: recovery and repair costs on a large machine can be significant

This isn't an exhaustive list. Every business is different, your policy needs will depend on your specific circumstances. But it's a starting point.

How Different Machines Create Different Transit Risks

Not all plant is the same, and transit risk varies accordingly.

An excavator is one of the most commonly transported machines in New Zealand. They're heavy, they're tall, and they need to be properly secured. A machine that's not correctly loaded is a risk to everyone on the road, and a potential claim waiting to happen.

A digger, whether that's a mini excavator or a larger tracked machine, has similar considerations. Smaller machines are sometimes transported on trailers that aren't purpose-built for the task, which can create additional exposure.

A bulldozer is typically one of the heavier loads you'll move. The float requirements are significant, and the consequences of a load failure are serious. Transit cover for dozers needs to account for the full recovery and re-siting cost, which on a large machine can be considerable.

A skid steer loader is often moved more frequently than larger plant, sometimes multiple times a week. That frequency of transit exposure means the question of whether transit is properly covered matters more, not less.

And if your machine travels on public roads under its own power, rather than on a float, that's a different risk profile again. Mobile plant road cover addresses the specific liability and damage exposure that arises when plant is driven on public roads, and it's worth understanding how that interacts with your main plant policy.

What Gerrards Does Differently

When you go directly to an insurer, you get their policy. That's it. There's no one in your corner checking whether the transit provisions are adequate, whether the salvage cover is realistic for the size of your machines, or whether a Cook Strait crossing creates a gap in your cover.

At Gerrards, we work across up to 20 insurers. That means we can compare how different plant policies treat transit, and find the one that actually fits how you operate. We're not pushing a single product, we're finding what works for your situation.

And at claim time, that independence matters. We advocate for you, not the insurer. If there's a dispute about whether a transit incident is covered, you want a broker in your corner who knows the policy wording and knows how to push back.

We also review policies annually. Premiums change. Policy terms change. The way you operate changes. An annual review catches the gaps before they become expensive surprises.

Getting the Right Cover

Machinery transit insurance in NZ isn't a single product with a standard set of terms. It's a combination of policy provisions, extensions, and conditions that vary significantly between insurers and policy types.

The right approach is to start with how you actually operate: how often do you move machines, what routes do you use, do you cross Cook Strait, what size and type of plant are you transporting, and who's doing the transporting?

From there, a broker can identify the gaps in your current cover and find the policies that address them.
