Machinery & Mobile Plant Insurance NZ

What Machinery Insurance Typically Covers

Machinery insurance in NZ can include physical damage cover for accidental loss or damage to the machine itself, third-party liability while the machine is operating as a tool of trade, transit cover between sites, and optional extensions for hired-in plant, goods on hook, machinery breakdown, and loss of income during repairs.

What's covered depends heavily on which policy type the machine is placed in and which optional extensions have been confirmed in the schedule. Ancillary attachments, buckets, augers, blades, are often subject to sub-limits as a percentage of the machine's insured value. Mechanical breakdown is typically a separate cover from physical damage.

Talk to your broker about whether each extension applies to your situation, and confirm the position in writing before you rely on it.

What Affects Your Machinery Insurance Premium

Several factors influence what you'll pay for machinery insurance in NZ:

• Machine type and value: Higher-value machines and those with specialist components cost more to replace, which is reflected in the premium. Agreed value policies typically cost more than market value policies.
• How the machine is used: High-risk operating environments, forestry, demolition, underground work, attract higher premiums than lower-risk applications. Machines that are hired out carry additional exposure.
• Fleet size and claims history: A larger fleet with a clean claims record often attracts better rates than a single machine with a history of losses. Insurers look at the overall risk picture.
• Policy extensions selected: Optional extensions, breakdown cover, downtime cover, hired-in plant, goods on hook, each add to the premium. The right extensions are worth the cost; the wrong ones aren't worth paying for.
• Excess level: A higher excess reduces the premium. The right excess level depends on what your business can absorb without a claim, your broker can help you find the right balance.
• Location and storage: Where machines are kept overnight and how they're secured affects the theft and fire risk, which flows through to the premium.

The Problem With Machinery Insurance in NZ

Most plant owners think they're covered. They've got a policy, they pay the premium, and they assume the machine is sorted. Then something goes wrong, a rollover, a fire, a breakdown on a remote site, and they find out their claim sits in a gap between two policies that each point to the other.

That's not bad luck. That's a placement problem.

Machinery insurance in NZ is genuinely complicated, not because insurers make it that way on purpose, but because heavy equipment doesn't fit neatly into a single insurance category. A machine can be a vehicle (when it's travelling on the road), a tool of trade (when it's digging, lifting, or grading on site), and a business asset (when it's sitting in the yard). Different policy types respond to different situations, and if the wrong one is doing the heavy lifting, you'll find out at claim time.

At Gerrards, we come across this. A business owner comes to us after a declined claim or a big jump in their renewal premium. We look at their schedule and find a digger sitting on a commercial motor policy that excludes tool-of-trade operations, or a harvester on a material damage policy with no transit cover. The machine was insured. It just wasn't insured correctly.

The Three Policy Homes, and Why It Matters Which One You're In

Every piece of plant you own or operate belongs in one of three places. Getting the placement right is the foundation of everything else.

Mobile Plant Policies

These are purpose-built for heavy equipment used as a tool of trade. They're designed around how machines actually work, operating on site, moving between jobs, being hired out, carrying loads on hook. Many mobile plant wordings include extensions for things like goods on hook insurance, hired-in plant, ancillary attachments, and finance payment protection. Some extend to cover loss of income if a machine is off the road for an extended period.

For most contractors and plant operators, a specialist mobile plant policy is the right home for their equipment. But "specialist" doesn't mean "automatically complete", the extensions that matter most are often optional, and they need to be specifically requested and confirmed in the schedule.

Commercial Motor Policies

Many commercial motor wordings define a "vehicle" broadly, machines on wheels, tracks, or rollers are often included. That means a digger or a telehandler can end up on a commercial motor policy, sometimes deliberately, sometimes because it was the path of least resistance at renewal.

The catch? Commercial motor policies are built around road use. When a machine is operating as a tool of trade, digging, grading, lifting, some commercial motor wordings limit or exclude liability cover for that activity. The physical damage section may still respond, but the liability position can be exposed. Check the tool-of-trade definition in your policy wording carefully. It matters.

Material Damage Policies

Plant can also sit on a material damage or business assets policy as a scheduled item. This works reasonably well for equipment that stays in one place, a fixed generator, a workshop press, a stationary pump. For mobile plant that travels between sites, operates on public land, or gets hired out, a material damage policy often leaves gaps around transit, third-party liability, and tool-of-trade operations.

Machine Types: Where Each One Usually Belongs

Different machines have different risk profiles, and that affects both placement and the specific cover questions you need to ask. Here's how we think about the main categories.

Excavators and Diggers

Excavators are one of the most widely used pieces of plant. They work hard, they operate in high-risk environments, and they're expensive to repair or replace. Excavator insurance and digger insurance both belong on specialist mobile plant policies in most cases, the tool-of-trade liability exposure alone makes a commercial motor policy a poor fit for most operators.

Key questions: Are your attachments (buckets, augers, hydraulic hammers) covered as part of the machine, or do they need to be scheduled separately? Many plant wordings cap ancillary equipment at a percentage of the machine's insured value, if your attachment inventory is significant, check whether that cap creates a gap.

Tractors and Agricultural Machinery

Tractor insurance sits at an interesting intersection, tractors are registered vehicles, they travel on public roads, and they operate as tools of trade. Some agricultural operators put them on commercial motor policies. Others use specialist plant wordings. The right answer depends on how the tractor is used and what other equipment is in the fleet.

Harvester insurance is a separate conversation. Harvesters are high-value, seasonally critical machines with specific risks around foreign object ingestion and crop-related damage. Some plant wordings include specific extensions for agricultural implements, worth asking about.

Telehandlers, Skid Steers, and Loaders

Telehandler insurance and skid steer loader insurance are both areas where the goods-on-hook question comes up regularly. If your machine lifts loads that belong to someone else, you need to know whether damage to those loads is covered, and under what conditions. It's not automatic.

Cranes

Crane insurance is one of the more complex placements in the plant world. Cranes carry significant liability exposure, they often operate under contract conditions that impose specific insurance requirements, and the goods-on-hook risk is front and centre. A standard plant policy may not be sufficient without specific extensions confirmed in the schedule.

Bulldozers and Roading Plant

Bulldozer insurance and roading plant insurance share a common challenge: these machines work in environments where underground services damage is a real and expensive risk. If your machine strikes a buried cable, pipe, or conduit, is that covered? Many standard policies exclude it. Underground services damage cover is a specific extension worth discussing with your broker.

Forklifts

Forklift insurance is often treated as an afterthought, forklifts are common, they're relatively familiar, and some operators assume they're covered under a general business policy. The goods-on-hook exposure (damage to loads being carried) and the third-party liability risk in busy yards make proper placement important.

Dump Trucks and Tip Trucks

Dump truck and tip truck insurance straddles the road/site boundary more than almost any other machine type. These vehicles travel on public roads, operate on site, and carry loads. The policy home question, commercial motor or specialist plant, needs to be answered carefully, and the tool-of-trade liability position needs to be confirmed.

The Cover Questions Plant Owners Get Wrong

Beyond placement, there are specific cover questions that come up repeatedly. These are the areas where gaps are most commonly found.

Agreed Value vs. Market Value

How your machine is valued at claim time matters enormously. Market value settlements can leave you significantly short, especially for older machines that have been well-maintained and are worth more to your operation than the market would suggest. Agreed value machinery insurance locks in a settlement figure upfront. It costs more in premium, but it removes the argument at claim time.

Dry Hire and Wet Hire

If you hire your machines out, the insurance position changes. Dry hire and wet hire insurance are distinct situations, dry hire (machine only) and wet hire (machine plus operator) carry different liability profiles, and not all plant policies automatically extend to hired-out equipment. Check your policy wording, and check whether the hire agreement you're signing creates any obligations around insurance that your current policy doesn't meet.

Hired-In Plant

The flip side: if you hire machines in from another party, what happens if you damage them? Hired-in plant insurance covers your liability for damage to equipment you don't own but are responsible for. Some plant policies include this as an extension, but it's often subject to conditions around written hire agreements and maximum periods. Don't assume it's there. Confirm it.

Machinery Breakdown

Physical damage cover responds to accidents, collisions, fires, rollovers. It doesn't respond to mechanical or electrical breakdown. Machinery breakdown insurance is a separate cover, and for high-utilisation machines, it's worth serious consideration. A major mechanical failure on a critical piece of plant can be just as financially damaging as an accident.

Downtime and Loss of Income

When a machine is off the road, the cost isn't just the repair bill. It's the jobs you can't complete, the hire costs for a replacement, the contracts at risk. Machinery downtime cover addresses this, but it's almost always an optional extension, and it typically comes with conditions around minimum repair periods. Ask about it before you need it.

Road Cover and Transit

Most mobile plant policies cover machines on site. What about when they're travelling between sites? Mobile plant road cover and machinery transit insurance address the gap between the yard and the job. If your machines travel on low-loaders or under their own power on public roads, confirm how your policy responds during transit.

Financed Machinery

If a machine is under a finance or lease agreement, the financier has an interest in it, and that creates specific insurance obligations. Insuring financed machinery isn't just about having cover; it's about having the right cover, with the financier's interest noted correctly, and understanding what happens to a settlement if there's still money owing on the machine.

Attachments

Buckets, augers, compactors, hydraulic hammers, plant attachments insurance is an area where the gap between what owners assume and what's actually covered can be significant. Many plant wordings include ancillary equipment up to a percentage of the machine's insured value. If your attachment inventory exceeds that threshold, the excess needs to be scheduled separately.

The Mobile Plant vs. Commercial Motor Question

We've touched on this above, but it deserves its own mention. Mobile plant vs. commercial motor is a genuine placement decision with real consequences, particularly around tool-of-trade liability. If you're not sure which policy home your machines are in, or why, that's worth a conversation.

When a Claim Gets Declined

If your machinery claim has been declined, don't accept it as the final word. Machinery claim declined situations are often recoverable, especially where the decline is based on a policy interpretation that a broker can challenge. At Gerrards, we advocate for clients at claim time. That's not something a direct insurer can do for you.

A Practical Checklist: What to Confirm With Your Broker

Before your next renewal, work through this list. If you can't answer yes to all of these, there's a conversation to be had.

• Policy home confirmed: Is each machine in the right policy type for how it's used?
• Tool-of-trade liability: Is third-party liability covered while the machine is operating as a tool of trade?
• Attachments scheduled: Are all ancillary attachments covered, and does the cap in your policy wording create a gap?
• Agreed value confirmed: Do you know how your machine will be valued at claim time?
• Hired-out cover: If you hire machines out, does your policy extend to hired equipment?
• Hired-in cover: If you hire machines in, are you covered for damage to them?
• Transit cover: Are your machines covered while travelling between sites?
• Road use confirmed: If machines travel on public roads under their own power, is that position clear?
• Breakdown cover: Do you have separate cover for mechanical or electrical breakdown?
• Downtime cover: If a machine is off the road for an extended period, is there cover for lost income or hire costs?
• Finance noted: If machines are financed, is the financier's interest correctly noted on the policy?
• Underground services: If your machines work near buried services, is that risk addressed?

What Gerrards Does Differently

We're an independent brokerage. We don't work for any insurer, we work for you. That means when we place your plant fleet, we're comparing options across up to 20 insurers to find the right policy home for each machine, not the easiest option or the one that pays us the best commission.

At renewal, we review your schedule. Machines get added, sold, upgraded, and hired out, and policies that made sense two years ago can develop gaps without anyone noticing. We look for those gaps before they become claim problems.

And if a claim does go sideways, we fight for you. A direct insurer has a conflict of interest at claim time, they're both your insurer and the one deciding whether to pay. We don't have that conflict. Our job is to get you the best outcome, and we'll push back on a decline or a low settlement when the case supports it.

That's not marketing. That's just how a broker should work.
