Third party only is the minimum level of motor vehicle insurance available and covers damage or injury that your minibus causes to other people or their property. It does not cover damage to your own vehicle. Suitable only for very low-value vehicles where comprehensive cover is uneconomical.
Third party only insurance is the minimum level of motor vehicle cover available in New Zealand. For commercial minibus operators carrying passengers, it represents the absolute floor of legal protection — and in most practical cases, it is not sufficient on its own for passenger-carrying operations. Understanding what it covers, what it doesn't, and when it might be appropriate helps operators make responsible decisions.
What Third Party Only Covers
Third party only cover provides liability protection for damage or injury you cause to other people or their property. If your driver is at fault in an accident and damages another vehicle, third party cover pays to repair or replace that vehicle. If the accident causes injury to the other driver or passengers in the other vehicle, third party cover pays for associated claims up to the policy limit.
It also covers legal defence costs — if the other party pursues a civil claim, your insurer will defend the claim and pay any awarded damages, up to the liability limit.
This is the full scope of what third party only covers. It provides no cover for your own vehicle — not for collision damage, theft, fire, flood, hail, or any other event that damages your own asset.
Third Party Only and Passenger-Carrying Operations
For passenger-carrying operations, third party only creates a significant protection gap. It does not include passenger liability cover (claims from your own passengers), and it provides no protection for the vehicle itself. If the vehicle is essential to your operation — which it almost always is — losing it to an at-fault accident with no vehicle cover creates major operational and financial consequences.
Most advisers recommend against third party only for any active passenger transport operation. The premium saving is typically modest relative to the risk exposure, and the reputational and operational consequences of an uninsured total loss are severe.
When Third Party Only May Be Appropriate
The narrow circumstances where third party only might be appropriate: a very low-value vehicle (under $3,000 market value) that is rarely used, where the operator has the financial capacity to absorb a total loss, and where the vehicle is not essential to operations. An older minibus kept as a backup that is driven only a few times per year might fit this profile.
Even then, the absence of fire and theft cover means a vehicle stored in a yard is at risk with no protection. Most operators who consider third party only end up concluding that at least third party fire and theft is a better risk balance.
Not-at-Fault Accidents and Third Party Only
One source of confusion is the not-at-fault scenario. If another driver causes an accident that damages your minibus, you may be able to recover costs from their insurer — but only if the other driver is insured and their liability can be established. In New Zealand, where approximately 15–20% of vehicles are uninsured, there is a real risk of being hit by an uninsured driver with no recovery option. A comprehensive policy removes this dependency by covering your own vehicle regardless of fault.
Liability Limits
Third party only policies have a stated liability limit — the maximum amount the insurer will pay for a single incident. For commercial minibus operations, standard third party limits may be insufficient if a serious multi-vehicle accident results in significant property damage and injury claims. Ensuring the liability limit is appropriate for the scale and risk of your operation is important even for operators who choose the minimum cover level.

Frequently Asked Questions
Is third party only sufficient for a community minibus?
No — third party only provides no cover for your own vehicle and no passenger liability protection. For any active passenger-carrying operation, at least third party fire and theft (ideally comprehensive) is recommended. The premium saving is typically not worth the risk exposure.
What happens if an uninsured driver hits my minibus and I have third party only?
Third party only covers damage you cause to others. If an uninsured driver damages your vehicle, you have no insurance claim available — you would need to pursue the other driver personally, which may be difficult or impossible. A comprehensive policy covers your vehicle regardless of the other driver's insurance status.
What are the liability limits on a third party only policy?
Liability limits vary by policy and insurer. Standard commercial vehicle policies typically offer limits from $1M to $5M or more. For passenger-carrying operations, ensure the liability limit is appropriate for the potential scale of a serious incident — especially if international tourists or multiple passengers are involved.
Can I add passenger liability to a third party only policy?
Some insurers offer passenger liability as an add-on to third party only policies. If you are carrying passengers in any capacity, passenger liability cover is strongly recommended. However, upgrading to at least third party fire and theft or comprehensive is usually a more cost-effective overall approach.
Is third party only cover a legal requirement for minibuses?
New Zealand does not mandate a specific level of insurance for motor vehicles, but operating without adequate insurance is legally and financially irresponsible. For commercial operators, maintaining adequate insurance is also a condition of a Transport Service Licence.
