About This Data
Summary
- Whether you're buying a used car or new car, arranging finance, or comparing insurance, many drivers wonder how long the car will actually last.
- To help answer this question, we've analysed the Ministry of Transport's official vehicle fleet data to give you data-based New Zealand answers.
- The data used in this guide is sourced from actual odometer readings when vehicles leave the New Zealand fleet (scrapped, exported, or deregistered) and outlines how far different types of cars travel before they turn the last corner. You can access the dataset on the Ministry of Transport's website.
Key Findings (from 2025's published NZTA data)
- Average petrol car lifespan: 195,134 km
- Average diesel car lifespan: 242,140 km (+47,000 km more than petrol)
- Utes and vans last longest: 249,427 km average
- New Zealand-new vehicles outlast used imports by 21,000 km (as to be expected given they start their life as a new car)
- Larger engines last longer: 3000cc+ vehicles average 225,042 km
- The average New Zealand vehicle age is 14.8 years, and 63% of the cars on our roads are 10+ years old
- NZ has one of the oldest car fleets in the developed world: Average age 14.8 years - 4+ years older than Australia (10.6 years) and over 5 years older than the UK (9.0 years) based on overseas government fleet reports.
- Cars are lasting shorter lives than five years ago: Petrol vehicles scrapped in 2023 averaged 17,000 fewer km than in 2019; diesels dropped a massive 21,000 km.
- Diesel power pays off big: Diesel cars and utes outlast petrol ones by ~47,000–54,000 km on average - that's 24–28% more life.
- Rural vs City: Southland tops the country with nearly one vehicle per person (996 per 1,000 residents), while Wellington has the lowest at just 706.
- Old cars ply our roads: 43% of the fleet is 15+ years old
- Used Japanese imports still dominate: 41% of all light vehicles arrived second-hand - down from a 2007 peak of 49%, but still massive by global standards and the main reason our fleet stays so old.
- Big engines = big longevity: Vehicles with 3000cc+ engines average 225,000 km - 30,000+ km more than small city cars under 1350cc, thanks to highway-friendly use and tougher builds.

About This Data
- All statistics in this guide come from the Ministry of Transport's official New Zealand Vehicle Fleet Statistics, published annually in November/December.
- Next update expected: December 2026 (when new fleet statistics are released)
Car Lifespan by Vehicle Type
The table below shows how far different types of vehicles travel before being removed from the New Zealand fleet register. The 'average odometer at disposal' is the final reading recorded at the vehicle's last warrant of fitness before it was scrapped, exported, or otherwise deregistered.
Important: Diesel vehicles and light commercial vehicles (utes, vans) significantly outlast petrol passenger cars. If you're doing high kilometres or need a work vehicle, these numbers support choosing a diesel ute or commercial vehicle - they're built to last.

| Vehicle Type | Average Lifespan | Notes |
|---|---|---|
| Light commercial vehicles (utes & vans) | 249,427 km | Built for heavy use |
| Diesel vehicles | 242,140 km | +47,000 km vs petrol |
| NZ-new vehicles | 213,930 km | +21,000 km vs used imports |
| Light passenger vehicles (cars) | 195,723 km | Overall average |
| Petrol vehicles | 195,134 km | Most common fuel type |
| Used imports (Japan) | 193,123 km | Arrive with 50,000-100,000km already |
How Engine Size Affects Lifespan
Bigger engines tend to last longer. This isn't because small engines are badly made - it's about how the cars are used. Larger vehicles arguably often do more highway driving and less stop-start urban work. They're also typically owned by people who drive longer distances.
| Engine Size | Average Lifespan | Typical Models |
|---|---|---|
| 3000cc+ (large SUVs, V6/V8) | 225,042 km | Land Cruiser, Patrol, Highlander |
| 2000-3000cc (mid-size) | 212,180 km | Camry, Accord, CX-5, RAV4 |
| 1600-2000cc (compact) | 196,850 km | Corolla, Civic, Mazda3, Golf |
| 1350-1600cc (small) | 178,452 km | Fit/Jazz, Swift, Yaris, Demio |
| Under 1350cc (city cars) | 162,753 km | Micra, Alto, i10, Spark |
Cars are Not Lasting as Long (But Average Age is Increasing)
The data confirms that car lifespans have been declining over the past five years - vehicles scrapped in 2023 had lower odometer readings than those scrapped in 2019. We don't have valid insights to suggest why this is the case right now.
Know This: Diesel lifespans dropped by 21,000 km over five years; petrol dropped by 17,000 km. This matters for anyone buying a high-mileage vehicle - the remaining useful life may be shorter than historical averages suggest.

| Year | Diesel | Petrol | NZ-New | Used Import |
|---|---|---|---|---|
| 2019 | 263,150 km | 212,173 km | 232,607 km | 209,336 km |
| 2020 | 260,896 km | 208,995 km | 230,221 km | 205,815 km |
| 2021 | 258,987 km | 206,525 km | 228,860 km | 202,730 km |
| 2022 | 252,265 km | 202,501 km | 225,792 km | 197,989 km |
| 2023 | 242,140 km | 195,134 km | 213,930 km | 193,123 km |
Know This: Vehicles have been ageing steadily since 2000. Back in 2000, the average vehicle was under 12 years old. Now it's nearly 15; that's three years added to the average age over two decades - and it's still climbing.
| Year | Avg Age | 10+ Years | 15+ Years | 20+ Years |
|---|---|---|---|---|
| 2000 | 11.8 years | 46% | 24% | 9% |
| 2005 | 12.3 years | 52% | 28% | 10% |
| 2010 | 13.5 years | 57% | 34% | 14% |

New Zealand's Vehicle Fleet - Age of Cars and Must-Know Information
Our table outlines what New Zealand's light vehicle fleet looks like (as at December 2024). We aim to help you understand where your car fits and emphasise that driving an old car is normal, as supported by data.
Know This: New Zealand has one of the oldest vehicle fleets in the developed world. If you're driving a 15-year-old car, this is not unusual - you're in the largest age bracket.
As the tables outline below, nearly half the fleet (43%) is 15 years or older. This arguably has some practical implications:
It also means the second-hand market has plenty of older vehicles - so prices reflect this reality.

As the tables outline below, nearly half the fleet (43%) is 15 years or older. This arguably has some practical implications:
- Parts availability becomes an issue for some models
- Safety features lag behind modern standards, and
- Fuel efficiency is generally worse.
It also means the second-hand market has plenty of older vehicles - so prices reflect this reality.
| Statistic | Value | Context |
|---|---|---|
| Total light vehicles registered | 4,309,833 | Population: 5.29 million |
| Average vehicle age | 14.8 years | One of oldest fleets in OECD |
| Vehicles 10+ years old | 63.5% | 2.74 million vehicles |
| Vehicles 15+ years old | 43.3% | 1.87 million vehicles |
| Average km driven per year | 10,623 km | Per vehicle average |
| Petrol vehicles in fleet | 68.5% | 2.95 million vehicles |
| Diesel vehicles in fleet | 21.4% | 923,050 vehicles |
| Electric & plug-in hybrid | 2.6% | 113,121 vehicles |
| Vehicle Age | Number | % of Fleet | Cumulative |
|---|---|---|---|
| 0-4 years (newest) | 695,187 | 16.1% | 16.1% |
| 5-9 years | 876,897 | 20.3% | 36.5% |
| 10-14 years | 870,374 | 20.2% | 56.7% |
| 15-19 years | 952,517 | 22.1% | 78.8% |
| 20+ years (oldest) | 914,858 | 21.2% | 100% |
Which Cars Are Oldest? Age by Type and Origin:
Not all vehicles are equally old. Based on the data:
- NZ-new diesels (mostly utes) are the youngest category at under 10 years average.
- Used import diesels are the oldest at over 22 years - many were manufactured in the early 2000s or late 1990s.
- The pattern is clear: NZ-new vehicles are younger, used imports are older.
- Diesel utes bought new are the youngest category because businesses replace them regularly. Used import petrol cars - the backbone of NZ's affordable car market - are by far the oldest.
| Vehicle Category | Average Age | Context |
|---|---|---|
| NZ-new petrol vehicles | 13.5 years | Youngest petrol category |
| NZ-new diesel vehicles | 9.7 years | Youngest overall (many utes) |
| Used import petrol vehicles | 18.1 years | Bulk of older fleet |
| Used import diesel vehicles | 22.3 years | Oldest category |
| Electric vehicles (BEVs) | ~3 years | Almost all recent imports |
Used Imports - What You Need to Know
New Zealand is one of very few developed countries that allows mass importation of used vehicles. About 41% of our fleet arrived as second-hand imports, mostly from Japan. This shapes everything about our vehicle age profile.
Used imports peaked at 49% of the fleet in 2007 and have been slowly declining. This is because of tighter import standards (up until 2026 per this article from newsroom), the Clean Car Discount (which ended in 2023), and rising incomes making new cars more accessible. However, our view is that 41% is still a massive proportion by international standards.

Understanding Why New Zealand's Vehicle Fleet is So Old (and What it Means for Drivers)
Three factors create New Zealand's uniquely old fleet:
The result of these factors means New Zealand's average vehicle age is around 14.8 years, compared to 10.6 years in Australia and 9.0 years in the UK based on overseas government fleet reports.
What This Means for You
For Car Buyers
For Car Insurance
For Car Finance
- Used import policy: We're one of the very few developed countries that allow mass importation of used vehicles. About 41% of our fleet arrived second-hand from Japan, already 5-8 years old. Then they stay on our roads for another decade or more.
- High new car prices: Small market + isolation = expensive new cars. When new vehicles cost more, people buy used and keep them longer.
- Limited public transport: In every city, most New Zealanders genuinely need a car for daily life. When you must have transport, you keep your car running even when it's old — because there's no alternative.
The result of these factors means New Zealand's average vehicle age is around 14.8 years, compared to 10.6 years in Australia and 9.0 years in the UK based on overseas government fleet reports.
What This Means for You
For Car Buyers
- Older cars are normal - don't assume a 15-year-old car is automatically a bad buy
- Factor in remaining lifespan - a petrol car at 150,000 km has limited life left
- Parts availability becomes an issue for vehicles over 20 years old
- Safety features on older cars lag significantly behind modern standards
- More information: Buying a used car
For Car Insurance
- Agreed value is often better than market value for older cars in good condition
- Market values for 15+ year old cars can be unpredictable
- More information: Compare car insurance
For Car Finance
- Match your loan term to the vehicle's remaining useful life
- Be careful about taking a 5-year loan on a car that might only last three more years

Vehicle Ownership by Region
Vehicle Ownership by RegionVehicle ownership varies significantly across New Zealand. Rural and provincial regions tend to have higher ownership rates (more vehicles per person) because public transport options are limited. Urban centres like Wellington and Auckland have lower per-capita rates due to better public transport and higher housing density.
The table below is ordered by vehicle ownership rate (highest to lowest per 1,000 population).
New Zealand average: 815 vehicles per 1,000 population (4,309,833 total vehicles)

The table below is ordered by vehicle ownership rate (highest to lowest per 1,000 population).
New Zealand average: 815 vehicles per 1,000 population (4,309,833 total vehicles)
Key Regional Insights
- Southland has the highest ownership rate (996 per 1,000) — nearly one vehicle per person. Rural areas with limited public transport require personal vehicles.
- Wellington has the lowest rate (706 per 1,000) — likely due to compact urban form and reasonable public transport options.
- Auckland has low per-capita ownership but dominates total numbers — 31% of all vehicles are registered in Auckland.
- South Island provincial regions consistently show higher rates — Canterbury, Nelson/Marlborough, and West Coast all exceed 900 per 1,000.

Frequently Asked Questions
How many kilometres should a used car have?
We suggest you use 10,600 km per year as your baseline. For example, a 10-year-old car "should" have roughly 106,000 km. Significantly less (say, 60,000 km) suggests light use and prompts the question of why it was driven so little.
Significantly more (say, 150,000 km) means heavy use - this is not automatically bad, but you will need to inspect more carefully and check the service history for consistent maintenance.
For Japanese used imports, add the km they arrived with. A car showing 95,000 km that arrived with 60,000 km has only done 35,000 km on NZ roads - about 3 years of average driving, regardless of how old it is.

Is 200,000 km too many for a car?
It depends entirely on the vehicle type:
Important: The raw number doesn't tell you much; instead, the vehicle type does.
- Petrol car at 200,000 km: You're at or beyond average lifespan (195,000 km). Major components are, unless they've already been replaced, statistically at end-of-life. Whatever the condition, you need to budget for significant repairs or be prepared to replace the car soon.
- Diesel car at 200,000 km: You're around 80% of the average lifespan for a diesel car per our tables above (242,000 km). Expect 40,000+ km of normal use remaining. Despite what appear to be huge odometer readings, this is a mid- to late-life diesel, not an end-of-life one.
- Diesel ute/van at 200,000 km: You're at around 80% of average lifespan (249,000 km). These vehicles regularly run to 250,000-300,000 km with proper maintenance. Still has plenty of working life.
Important: The raw number doesn't tell you much; instead, the vehicle type does.
Why do diesel cars last longer than petrol?
Three factors combine:
- Engineering: Diesel engines are built heavier-duty to handle higher compression ratios. This means stronger blocks, heavier internals and more robust construction overall.
- Usage patterns: Diesels tend to do more highway driving (where they're most efficient) and less stop-start urban work. Highway km is easier on engines than city km.
- Maintenance culture: Many diesels are commercial vehicles where downtime costs money. Owners maintain them properly because they can't afford breakdowns. The average diesel gets better care than the average petrol car.
Should I buy a used import or a New Zealand-new vehicle?
Neither is automatically better - to make a decision, you'll need to calculate the value:
Our View: A cheaper used import with shorter remaining life might cost more per year than a more expensive New Zealand-new car with longer remaining life. Or, depending on the calculations, it might cost less. The numbers vary by specific vehicle - please don't make any assumptions when it's easy to make the calculations.
- Estimate the remaining life for each option
- Divide the purchase price by the remaining life (in years) to get the cost per year
- Compare the cost per year, not just the purchase price

Or, depending on the calculations, it might cost less. The numbers vary by specific vehicle - please don't make any assumptions when it's easy to make the calculations.
How long should my car loan be?
If you're considering car finance, please be aware that the shorter the loan period, the less interest you'll pay. This means higher repayments but savings overall. For the purposes of using lifespan data, you'll need to calculate remaining life as average lifespan minus current km, divided by 10,600, then choose a loan term at least 2 years shorter.
For example:
Important: If a lender offers you a longer term, that doesn't mean it's sensible or helpful - they're secured against the car, but you are personally liable for it, which means you'll need to clear the balance no matter what happens to the vehicle later on.
For example:
- Petrol car at 100,000 km → ~9 years remaining → maximum 7-year loan
- Petrol car at 150,000 km → ~4 years remaining → maximum 2-3 year loan
- Diesel ute at 150,000 km → ~9 years remaining → maximum 7-year loan
Important: If a lender offers you a longer term, that doesn't mean it's sensible or helpful - they're secured against the car, but you are personally liable for it, which means you'll need to clear the balance no matter what happens to the vehicle later on.
What annual mileage should I tell my insurer?
Car insurance policies need to have the correct information to be valid, so you must tell them the truth. Check your last two WoF certificates for actual odometer readings and calculate your real annual km. If you don't have records, estimate conservatively based on your driving pattern:
Know This: Underestimating to get a lower car insurance quote is unwise, as it can void your cover or reduce your payout when you need it most. Our guide to saving on car insurance has more information.
- Work from home and retired: 5,000–7,000 km
- Short commute: 8,000–10,000 km
- Average commuter: 10,000–15,000 km
- Long commute/trades: 15,000–20,000+ km

Why do larger engines last longer?
It's correlation, not just causation. Larger engines appear in vehicles that are:
For example, a 3.0L engine in a Land Cruiser designed for 300,000 km is a different proposition from a 1.0L engine in a city car designed for 150,000 km - the engine size reflects the vehicle's purpose and build quality. However, a well-maintained small engine can outlast a neglected large one, so our data isn't a rule.
- Used for highway/touring driving (easier on engines)
- Often built more robustly overall (Land Cruiser vs Yaris)
- Owned by people who can afford proper maintenance
- Designed for longevity rather than just economy

Is it worth buying a high-mileage car?
Potentially, if:
Our View: High-mileage cars can be an excellent value if bought right. However, many New Zealanders are offered "low-mileage prices" for high-mileage cars. If the price doesn't reflect the reduced remaining life, walk away.
- The price genuinely reflects the mileage (not just slightly discounted)
- You can verify consistent maintenance (this includes service records, receipts)
- You have a budget for repairs when components reach end-of-life
- You won't finance its purchase for longer than its remaining life
- It's a vehicle type known for longevity (diesel, commercial, etc.)
Our View: High-mileage cars can be an excellent value if bought right. However, many New Zealanders are offered "low-mileage prices" for high-mileage cars. If the price doesn't reflect the reduced remaining life, walk away.
How often should I service my car to maximise lifespan?
Follow the manufacturer's schedule - they engineered the car and know what it needs. Typical intervals:
Important: The cost of regular servicing over a car's life is a fraction of the cost of a single major repair caused by skipped maintenance. An engine rebuild costs $5,000-$15,000, while regular oil changes cost $100-150 each, so it's important not to neglect any servicing.
- Oil and filter: Every 10,000-15,000 km or 12 months, whichever comes first
- Air filter: Every 20,000-40,000 km
- Spark plugs: Every 30,000-100,000 km, depending on type
- Timing belt: Every 80,000-100,000 km — this is critical and expensive if it fails
- Transmission fluid: Every 60,000-100,000 km for automatics
- Coolant: Every 2-5 years, depending on type

Do these lifespans apply to electric vehicles?
We don't have enough New Zealand data yet. EVs are only 2.6% of the fleet, and most are recent arrivals - the average age is around 3 years. With few EVs being scrapped, we don't know how long they will last overall.
However, international data suggests EV drivetrains can last 300,000+ km, but battery degradation is the key variable. A battery that's lost 30% of its range might still "work" but may not suit your needs. We will update this guide as New Zealand-specific EV lifespan data becomes available.

What about hybrid vehicles?
Hybrids (non-plug-in, like the Toyota Aqua or Prius) are well-established and have proven longevity. The combination of a petrol engine and an electric motor actually reduces wear on both: the electric motor handles stop-start driving, which's hard on petrol engines, while the petrol engine handles highway work, where it's efficient.
Many Uber and taxi fleets use Prius hybrids specifically because they last well at high km. Battery replacement is a concern, but modern hybrid batteries typically last 200,000+ km, and replacement costs have dropped significantly. We estimate that a hybrid with good battery health should last as long as, or longer than, an equivalent petrol-only vehicle.
