The insurance section is the part of a car rental booking most people skim, then worry about at the counter. Words like excess, bond and liability reduction get thrown around, and it is hard to know whether you need to pay for more cover or whether you are already protected.

What basic cover usually includes
Most rental cars in New Zealand come with basic insurance built into the daily rate. It usually covers damage to the rental car, theft and damage you cause to other people’s vehicles or property, but with one important catch: the excess.
The excess is the amount you pay towards any claim if the car is damaged or stolen while you have it. On basic cover it is often several thousand dollars, so a minor scrape in a car park can still be expensive.
It is worth knowing that New Zealand has no compulsory third party insurance for drivers. If another driver hits your rental car and they are uninsured, recovering the cost from them can be difficult, which is one reason the rental company’s own cover matters.
Excess, bond and pre-authorisation
These three words often appear together, and they mean different things.
- Excess
- The most you will pay towards damage or theft under your cover
- Bond
- An amount held by the rental company at pick-up, often linked to the excess
- Pre-authorisation
- A hold placed on your credit card for the bond, released after the car is returned
A pre-authorisation is not a charge, but it does reduce your available credit until it is released, and your bank can take several working days to release it. Make sure your card has enough room on it, especially on a long trip.
Reducing your excess
Most rental companies offer one or two extra levels of cover for a daily fee. These typically:
- Lower the excess, sometimes to zero
- Reduce or remove the bond, so less is held on your credit card
- Add cover for things basic insurance leaves out, such as windscreens, tyres or lost keys
Whether it is worth paying depends on how long you are hiring for, where you are driving and how comfortable you would be paying the full excess if something went wrong. On a short city hire the daily fee adds up to little; on a month-long road trip it becomes a bigger decision.
Travel insurance, your own insurer and credit cards
You do not have to buy excess cover from the rental company. Consumer Protection points out that you may get cheaper cover through your own insurer, a motor vehicle association such as the AA, or a travel insurance package.
If you rely on one of these, check the details carefully:
- Does it cover domestic trips, not just overseas travel?
- What is the maximum it pays, and is that enough to cover the rental excess?
- Does it exclude certain vehicles or roads, such as unsealed roads?
- How do you claim? Usually the rental company charges the excess to your card, and you claim it back from your insurer afterwards.
Some premium credit cards include rental car excess cover. Read the card’s policy wording or call the provider, as there are often conditions, such as paying for the whole hire on that card.
What rental insurance usually does not cover
Even full cover has exclusions. Common ones include:
- Damage to the underbody of the car
- Driving on beaches, off-road tracks or prohibited roads, which many companies list by name in their terms
- Unlisted drivers, so make sure everyone who drives is on the agreement
- Driving under the influence of alcohol or drugs, or driving recklessly
- Personal belongings left in the car
- Returning the car late or outside the agreed hire period
Read the list of exclusions before you sign. If something matters to your trip, such as a gravel road to a holiday home, ask about it at the counter.
Injuries are a separate system
Rental insurance covers the car and other people’s property, not injuries. In New Zealand, injuries from accidents are covered by ACC, which applies to everyone in the country, including visitors. ACC’s page on what ACC covers explains the details.
Protect yourself at pick-up and return
Good habits matter as much as the cover you choose.
- Inspect the car before you drive away. Note every mark on the inspection report and take photos.
- Report damage straight away. If something happens during the hire, tell the rental company as soon as possible and take photos of the scene.
- Return it on time and inspected. Take photos of the car at drop-off, especially if you return it after hours.
If you disagree with a damage charge, tell the company. Consumer Protection notes that the Consumer Guarantees Act requires a rental car to be safe, roadworthy and fit for purpose, and that a credit card chargeback or the Disputes Tribunal may be options if a dispute cannot be resolved.
Questions to ask about rental insurance
- What is the excess on basic cover, and how much is the bond?
- What do the higher cover options include, and what does each cost per day?
- Are windscreens, tyres and lost keys covered?
- Which roads or areas are excluded?
- When is the pre-authorisation released?
