Carriers Liability Insurance

When you carry goods belonging to someone else, you take on legal responsibility for those goods. If they are lost, stolen, or damaged while in your care, the freight owner will hold you liable. Carriers liability insurance covers this legal liability — and for any operator carrying third-party freight, it is as essential as the motor vehicle cover itself.

The Legal Framework — Contract and Commercial Law Act 2017

The Contract and Commercial Law Act 2017 (CCLA) governs the liability of carriers in this country. It replaced and consolidated the Carriage of Goods Act 1979 and establishes the framework under which carriers are held responsible for freight.

Under CCLA, a carrier operating under a "road carrier's risk" arrangement is strictly liable for loss or damage to goods in transit — meaning you are liable regardless of fault. Even if the damage was caused by road conditions outside your control, a third-party vehicle, or an event you could not have prevented, you remain liable to the freight owner.

A "limited carrier's risk" arrangement limits your liability to cases where the loss is caused by your negligence. Under this arrangement, you are not automatically liable — but you must prove the loss was caused by an Act of God, an inherent defect in the goods, or circumstances entirely outside your control. That defence requires you to investigate, gather evidence, and potentially litigate — which has costs and risks of its own.

Your carriers liability policy responds to both situations. It pays the freight owner's claim (up to the policy limit) and covers your legal defence costs in disputed claims.

What CCLA Actually Means in Practice

Consider two real-world scenarios that illustrate how CCLA operates:

Scenario 1: Refrigerated goods spoilage due to reefer failure. You are carrying a load of chilled dairy products valued at $180,000 for a major food distributor. Your refrigeration unit fails overnight while the truck is parked at a truck stop. By the time the failure is discovered, the entire load is above temperature and condemned. The freight owner claims $180,000. Under a road carrier's risk contract, you are liable regardless of whether the reefer failure was caused by a manufacturing defect, a maintenance issue, or an electrical fault. Your carriers liability policy — with a specific refrigeration failure extension — pays the claim.

Scenario 2: Timber contract not met due to road accident. You are running a timber load under contract to a sawmill. Your truck is involved in a serious accident on a rural highway, the load is destroyed, and the mill misses a customer delivery deadline. The timber owner claims for the value of the timber ($65,000) and consequential loss of contract. Your carriers liability policy covers the cargo claim. Consequential loss cover — if you have that extension — responds to the downstream contract loss.

These scenarios illustrate why limits need to match your actual cargo values, and why extensions (refrigeration failure, consequential loss) are not optional extras for many operators.

Choosing the Right Limit

The appropriate limit depends on the maximum value of freight you carry on any single journey. For general freight operators, $500,000 to $1,000,000 is typical. For operators carrying high-value cargo — refrigerated food, electronics, pharmaceuticals, livestock, building materials for construction projects — $2,000,000 or more may be appropriate.

Your broker should help you identify your highest realistic single-load exposure. Set your limit at at least 120% of that value — to allow for freight charges, customs duties (if relevant), and the insurer's settlement costs in addition to the cargo value itself. Underinsuring carriers liability is a common and costly mistake.

Bailment and Duty of Care

Beyond the CCLA framework, carriers owe a duty of care as bailees — parties who take temporary possession of another's property. The bailee is obliged to take reasonable care of the goods and return them in the same condition. Failure to meet this standard creates common law liability that exists independent of the CCLA framework.

This matters for situations that fall outside the CCLA scope — for example, goods held at a depot overnight, goods loaded but not yet in transit, or goods being unloaded at the delivery point. These are bailment situations: your carriers liability policy should confirm that cover applies throughout the custody period, not just when the wheels are turning.

Sub-Contracting Chain Liability

Many freight movements involve sub-contracting — a principal carrier accepts the freight contract and sub-contracts the actual movement to another operator. This creates a chain of liability. The principal carrier is liable to the freight owner under the original contract. If the sub-contractor causes the loss or damage, the principal carrier may still be liable to the freight owner and must then pursue the sub-contractor.

If you are a principal carrier using sub-contractors, your carriers liability policy should cover your liability for sub-contracted movements. If you are a sub-contractor, your own carriers liability policy covers your liability to the principal carrier. In both cases, the cover must be in place — [Transporting NZ](https://transportingnz.org.nz) recommends that all sub-contracting agreements specify minimum insurance requirements for sub-contractors.

Refrigeration Failure Extension

Standard carriers liability covers physical loss or damage to goods — not spoilage caused by equipment failure. Refrigeration failure cover (sometimes called "reefer breakdown extension") is a specific addition that covers cargo spoilage when the refrigeration or temperature-control system fails. For operators carrying chilled or frozen goods — dairy, meat, seafood, produce, pharmaceuticals — this extension is non-negotiable.

When reviewing this extension, check the policy conditions carefully. Some policies require documented evidence of regular refrigeration maintenance, temperature monitoring records, and prompt reporting when a failure is detected. Non-compliance with these conditions can result in a declined claim.

Dangerous Goods Disclosure

If you carry dangerous goods (HSNO-classified substances: Class 3 flammable liquids, Class 8 corrosives, Class 2 gases, or other regulated classes), your carriers liability policy must specifically include cover for dangerous goods incidents. Many standard policies exclude dangerous goods, or require a specific endorsement with additional information about the goods being carried.

Non-disclosure of a dangerous goods load is a material non-disclosure that can void your policy. If you are asked to carry a load and you are unsure whether it constitutes dangerous goods under HSNO, contact your broker before you load — not after an incident.

Limits, Deductibles, and the Claims Process

When a cargo claim arises, the process typically involves:

Notification: You must notify your insurer promptly — most policies require notification within a specified number of days of becoming aware of a potential claim. Late notification is grounds for reducing or declining the claim.

Cargo inspection: The insurer may appoint a cargo surveyor to assess the loss or damage before the goods are disposed of or repaired. Do not dispose of damaged goods without the insurer's agreement — this can prejudice your ability to recover.

Proof of value: You will need to demonstrate the value of the cargo at the time of loss — typically through the freight owner's invoice, shipping manifest, or customs documentation. High-value loads should have documentation ready before transport begins.

Deductible (excess): Carriers liability policies have a per-claim deductible — typically $500–$2,500 for standard freight, higher for specialist cargo. The deductible applies per incident, not per consignment item within an incident.

[Transporting NZ](https://transportingnz.org.nz) provides member guidance on claims documentation requirements — being prepared before a claim arises reduces the stress and complexity of the claims process considerably.

Reviewing Your Cover at Renewal

Carriers liability is not a set-and-forget cover. At every annual renewal, review whether your limit still reflects your current maximum single-load exposure. If you have taken on new contracts, started carrying higher-value freight, or moved into a new commodity sector (from general freight to refrigerated, for example), your limit may need to increase.

Also review the extensions in force: refrigeration failure, consequential loss, dangerous goods. If your operations have changed during the year — you started carrying ADG-classified goods, or took on a reefer trailer — make sure those changes have been reflected in mid-term policy endorsements, not discovered at claim time.

The cost of increasing a carriers liability limit from $500,000 to $1,000,000 is typically modest relative to the premium — often $800–$1,500 per year additional. The difference at claim time if a high-value load is lost without adequate limit can be $500,000 or more. Talk to your broker about right-sizing the limit at every renewal.
