Choosing between comprehensive, third party fire and theft, and third party only doesn't have to be a guessing game. The right level depends on your car's value, your financial situation, how you drive, and where you park. This guide walks through the key factors and real-world scenarios so you can match the cover level to your situation.
Before diving into which level suits you, here's a brief summary of what each one covers. If you already know the basics, skip ahead to the factors that matter.
Comprehensive is the most complete level. It covers damage to your own vehicle (accidents, weather, vandalism), theft, fire, and liability for damage you cause to other people's property or vehicles. Most NZ insurers also bundle in extras like windscreen cover and emergency transport. Our guide to comprehensive car insurance covers the detail.
Third party, fire and theft (TPFT) covers liability for damage to others, plus theft of and fire damage to your own car. What it does not cover is damage to your own vehicle from an at-fault accident. If you crash into a fence or another car and it's your fault, you're on your own for your car's repairs or replacement.
Third party only is the most basic level. It covers damage you cause to other people's property - and nothing else. Your car has no protection against theft, fire, weather, or accidents. It exists mainly to protect you from liability if you damage someone else's vehicle or property.
For a side-by-side breakdown, see our comprehensive vs third party comparison guide. The Citizens Advice Bureau guide to vehicle insurance also has a clear overview of the three levels.
| Scenario | Comprehensive | Third Party Fire & Theft | Third Party Only |
|---|---|---|---|
| You crash into another car (your fault) | Your car and theirs - both covered | Their car only - yours is not covered | Their car only - yours is not covered |
| Your car is stolen | Covered | Covered | Not covered |
| Your car catches fire | Covered | Covered | Not covered |
| Hail or storm damages your car | Covered | Not covered | Not covered |
| Someone vandalises your car | Covered | Not covered | Not covered |
| You hit a $90,000 Tesla at a roundabout | Their car covered (liability) | Their car covered (liability) | Their car covered (liability) |
There's no universal answer to which level is best. The right level depends on a handful of personal factors that are different for every driver. Here are the ones that matter most.
Your car's current value. This is the single biggest factor. The more your car is worth, the more you stand to lose - and the stronger the case for comprehensive cover. A $25,000 car that's written off in an at-fault accident is a devastating financial hit. A $2,500 car? Much less so. We'll look at the specific value thresholds in the next section.
Your budget and financial buffer. Could you replace your car from savings if it was written off tomorrow? If the answer is no, that's a strong signal towards comprehensive cover. If you have enough set aside to buy a similar vehicle without borrowing, a lower level of cover may be worth considering. The Sorted.org.nz budgeting tool can help you assess your financial position.
Whether you have finance on the car. If you're paying off a car loan or hire purchase, your finance agreement almost certainly requires you to maintain comprehensive cover. Dropping to a lower level would breach your contract and could have serious consequences. Check the fine print before making any changes.
Where you park overnight. Your parking situation affects your theft and damage risk. A locked garage is the lowest-risk option. On-street parking in a high-crime suburb is the highest. If your car is parked in a vulnerable spot, the theft and weather protection that comes with TPFT or comprehensive becomes more valuable.
How and where you drive. City commuters in heavy traffic face higher accident risk than someone who drives short distances in a quiet town. Higher annual mileage also increases your exposure. Drivers who spend a lot of time on the road may find the accident cover in comprehensive worth the extra cost.
Your risk tolerance. Some people sleep better knowing they're fully covered, even if the numbers suggest a lower level could work. Others are comfortable taking on more risk in exchange for lower premiums. Neither approach is wrong - it's a personal call.
This framework brings together the key factors into a practical guide. It's not a set of rules - just a starting point based on how these factors commonly line up for NZ drivers.
Use the table below to find the row that closest matches your situation. If you fall between rows, that's normal - compare estimates for both levels and see whether the price difference changes the equation.
Keep in mind that every insurer prices differently. The gap between comprehensive and TPFT can be surprisingly small in some cases, which may tip the balance toward more cover even when the car's value is modest. The Consumer NZ car insurance section has useful guidance on comparing these trade-offs.
| Your Situation | Car Value | Parking | Finance? | Cover Level Worth Considering |
|---|---|---|---|---|
| New or near-new car, still paying it off | $15,000+ | Any | Yes | Comprehensive (likely required by lender) |
| Reliable family car, sole household vehicle | $8,000 - $20,000 | Garage or driveway | No | Comprehensive |
| Mid-value daily driver, some savings buffer | $5,000 - $10,000 | Garage or driveway | No | Comprehensive or TPFT - compare both |
| Older commuter car, parked on street in city | $4,000 - $7,000 | On-street, urban | No | TPFT (theft and fire cover valuable here) |
| Lower-value car, could replace from savings | $3,000 - $5,000 | Garage or driveway | No | TPFT or third party only |
| Very low-value car, easy to replace | Under $3,000 | Any | No | Third party only |
| Weekend or second car, low mileage | $3,000 - $8,000 | Garaged | No | TPFT or comprehensive depending on value |
| High-value classic or modified car | $15,000+ | Garaged | No | Comprehensive with agreed value |
Walk through these questions to narrow down the right level for you
One of the most common questions in NZ car insurance is: at what car value should you drop from comprehensive to a lower level? There's no magic number, but looking at the maths helps frame the decision.
Consider a car worth $4,000. If you're paying $850 per year for comprehensive cover with a $500 excess, the maximum payout on a total loss would be $3,500 (value minus excess). After just two years of premiums ($1,700), you've paid almost half the car's value. After four years, you've paid more than the car was ever worth.
Now consider a car worth $15,000 with the same $850 annual premium and $500 excess. The maximum payout is $14,500 - far more than the premiums you'd pay over several years. The maths are clearly different.
As a rough guide that many NZ drivers and industry commentators use, the threshold tends to sit somewhere between $5,000 and $8,000. Below $5,000, the case for comprehensive weakens significantly. Above $8,000, most drivers find the cover worthwhile. In between, it depends on the other factors we've covered - parking, budget, how essential the car is to your daily life.
The Sorted.org.nz car insurance guide makes a similar point: the key is to weigh the premium cost against the realistic payout. If the annual premium is more than about 10% to 15% of your car's value, it's worth questioning whether comprehensive is the most effective use of that money.
Don't forget that car values drop every year. A policy that made perfect sense when you bought the car may not stack up at renewal three years later. Revisit this calculation at every renewal, not just when you first buy the policy.
Abstract rules only go so far. Here are five real-world scenarios that show how different situations lead to different cover choices. These are composites based on common NZ driving situations - not specific cases.
Scenario 1: Student with a 2008 Toyota Corolla worth $4,500. Parks on the street near the university in Dunedin. No savings buffer to speak of - losing the car would mean catching the bus for months. Comprehensive costs around $950 per year; TPFT costs around $420. In this case, the car is essential even though its value is modest. TPFT provides theft and fire protection at a much lower cost, and the street parking in a student area makes theft cover particularly relevant. Third party only would leave no protection if the car was stolen. TPFT may be the practical choice here.
Scenario 2: Family with a 2021 Mazda CX-5 worth $32,000. Still paying off $18,000 on a car loan. Parked in a locked garage in suburban Hamilton. The finance agreement requires comprehensive cover - so there's no decision to make on the level. The choice here is about the details within comprehensive: agreed value versus market value, excess level, and whether to add windscreen or NCB protection. With a financed car, agreed value is worth looking into carefully - our excess guide covers how to set the right excess level.
Scenario 3: Commuter with a 2016 Honda Jazz worth $9,000. Drives 25,000 km per year on Auckland motorways. Parks in a covered carport overnight. No finance. Has $5,000 in savings. This is squarely in the zone where comparing comprehensive and TPFT estimates makes sense. The high mileage increases accident risk, which favours comprehensive. But the $9,000 value isn't enormous, and there's a reasonable savings buffer. Getting estimates for both levels and comparing the price gap is the practical approach.
Scenario 4: Retiree with a 2006 Toyota Yaris worth $2,800. Drives mainly around town in Napier, does about 6,000 km per year, and parks in a garage. Has retirement savings. The car's value is low, the mileage is low, and the parking situation is low-risk. Third party only may suit this situation well - the liability protection covers the big risk (damaging someone else's expensive car), and the $2,800 car could be replaced without catastrophic financial impact.
Scenario 5: Tradie with a 2019 Ford Ranger worth $38,000. Used for work every day, carries tools, parked on job sites during the day and in a driveway overnight in Christchurch. No finance but the vehicle is essential for income. Comprehensive is the clear fit here - the car is high-value, essential for earning a living, and exposed to higher risk from work sites and daily heavy use. Losing this vehicle without cover would mean loss of income as well as the vehicle itself.
Your cover level isn't a set-and-forget decision. Life changes, and your insurance should change with it. Here are common situations where it makes sense to revisit your level.
Times to consider upgrading to comprehensive: You've bought a newer or more valuable car. You've moved somewhere with higher theft or weather risk. You've taken out finance on a vehicle. Your car has become more essential to your daily life (new job further from home, for example). You no longer have the savings buffer you once did.
Times to consider downgrading from comprehensive: Your car's value has dropped significantly since you last reviewed. You've paid off your car loan and are no longer required to have comprehensive. You've built up enough savings to absorb a total loss. You've moved to a lower-risk area with secure parking. You've acquired a second vehicle, reducing your dependence on any single car.
The best time to review is at renewal. Most NZ policies renew annually, and your insurer will send a renewal notice a few weeks before the date. That's your prompt to check your car's current value, reassess the factors above, and compare estimates. The ICNZ consumer information page has useful resources on reviewing your cover.
One important point: if you downgrade, make sure you do it at renewal rather than mid-policy. Cancelling a policy mid-term can attract fees, and some insurers apply short-rate cancellation charges. Ask your insurer about the process and any costs involved before making changes.
Choosing the wrong cover level is one of the most expensive mistakes in car insurance - and many Kiwi drivers make it without realising. Here are the pitfalls that come up most often.
Paying for comprehensive on a car that's barely worth the annual premium. If your car is worth $3,000 and you're paying $900 a year for comprehensive, the numbers don't add up. After three years of premiums, you've paid almost as much as the car is worth. Stepping down to TPFT or third party only could save you hundreds every year while still protecting you from the biggest risk - damaging someone else's property.
Dropping to third party only and forgetting about theft. Third party only covers damage to others - and nothing else. If your car is stolen, you get nothing. If it catches fire, you get nothing. For many drivers, third party fire and theft is a better middle ground because it provides theft and fire protection at only a modest cost increase over third party only. The AA Insurance car insurance page outlines what each level includes.
Assuming your finance company doesn't require comprehensive. Almost every car loan, hire purchase, and lease agreement in NZ requires the borrower to maintain comprehensive cover for the life of the loan. Dropping to a lower level - even if the maths seem to favour it - can breach your contract. Always check before making changes.
Never reviewing your cover level after the first year. Your car loses value every year. A cover level that made sense when the car was worth $15,000 may not make sense when it's worth $8,000. Set a reminder to reassess at every renewal.
Ignoring the price gap between levels. Many drivers assume comprehensive is dramatically more expensive than TPFT, but the gap is often smaller than expected - sometimes just a few dollars per month. Without checking, you could be under-insured for the sake of a saving that doesn't amount to much. Always compare estimates for multiple levels before deciding.
Choosing based on the premium alone without considering the excess. A low premium with a $1,500 excess and a higher premium with a $400 excess can look very different when you actually need to claim. Our guide to insurance excess explains how to find the right balance.
Once you've narrowed down the right cover level, the next step is comparing what different insurers offer within that level. Not all comprehensive policies are the same, and not all TPFT policies are the same either.
Start by getting estimates from multiple insurers. On Compare.org.nz, you can enter your details once and see estimated premiums from a range of NZ insurers. This gives you a quick picture of the market. From there, visit individual insurers for actual quotes with precise pricing.
When comparing policies at the same level, pay attention to the excess (both standard and voluntary), whether the policy uses agreed value or market value, what extras are included (windscreen cover, courtesy car, roadside assistance), and the insurer's claims process and reputation. Consumer NZ publishes customer satisfaction ratings that cover claims handling.
Also look at the no-claims bonus structure. How quickly does the discount build? Does the insurer offer NCB protection? A slightly more expensive insurer with a generous NCB structure could save you more over time. Our guide to saving on car insurance covers this in more detail.
Finally, read the policy wording - especially the exclusions section. Every NZ insurer is required to make their policy document available, usually as a PDF on their website. Look for exclusions that might affect you specifically: unlisted driver restrictions, business use limitations, modifications, or geographic exclusions. Tower, AMI, and AA Insurance all publish their policy documents online.
The Insurance & Financial Services Ombudsman (IFSO) website has information on what to look for in insurance contracts and what your rights are as a policyholder.
