Most New Zealanders think of car ownership in terms of the purchase price. The real number — the one that matters — is what the car costs you every year to keep on the road. For many households, it’s their second-biggest expense after housing.
A cheap used car ($8k purchase) typically costs $5,000–6,500/year all-in. A mid-range car ($18k) costs $7,000–9,000/year. A newer car ($35k) costs $10,000–14,000/year. Depreciation and insurance are the biggest costs — not petrol. Most New Zealanders underestimate car ownership costs by 40–60%.
Every Cost You Need to Count
1. Depreciation
Depreciation is the largest single cost for most car owners — but it’s invisible because you don’t write a cheque for it. It’s the value your car loses each year.
| Car age | Typical depreciation rate |
|---|---|
| New car, Year 1 | 15–20% of purchase price |
| Years 2–3 | 10–15% per year |
| Years 4–7 | 8–12% per year |
| 8+ years | 5–8% per year (slows on older cars) |
A $35,000 new car loses roughly $5,500–7,000 in Year 1 alone.
2. Insurance
| Coverage type | Typical annual cost |
|---|---|
| Third party only | $300–450 |
| Third party, fire & theft | $400–600 |
| Comprehensive (older/cheaper car) | $600–900 |
| Comprehensive (newer/more valuable car) | $900–1,800 |
Providers: AA Insurance, AMI, State, Tower, Youi, Trade Me Insurance. Get at least 3 quotes — rates vary significantly. Young drivers (under 25) pay a premium.
3. Warrant of Fitness (WoF)
WoF inspections are required every 12 months for vehicles less than 6 years old, and every 6 months for older vehicles (pre-2000 models).
- WoF inspection: ~$55–70 (varies by provider)
- Repairs to pass: Budget an additional $100–500/year for minor repairs (tyres, brakes, lights, windscreen chips)
4. Registration
Vehicle registration is renewed annually through NZTA.
- Registration (12 months): $108.64
- ACC levy: Included in registration fee — covers injury in accidents
5. Petrol
Petrol cost depends heavily on kilometres driven and engine size.
Assumptions: Regular 91 petrol at $2.50/litre
| Annual km | Fuel economy (L/100km) | Annual petrol cost |
|---|---|---|
| 10,000 km | 7L/100km | $1,750 |
| 15,000 km | 7L/100km | $2,625 |
| 20,000 km | 8L/100km | $4,000 |
| 15,000 km | 10L/100km (SUV/older) | $3,750 |
Average NZ driver covers around 13,000–15,000 km/year.
6. Servicing and Maintenance
| Vehicle age | Annual service estimate |
|---|---|
| Under 5 years (basic service) | $250–400 |
| 5–10 years (minor/major alternating) | $400–700 |
| 10+ years (higher risk of repairs) | $600–1,500+ |
Budget more for older vehicles — timing belts, suspension, brakes, and cooling systems all need attention as mileage increases.
7. Tyres
A set of 4 tyres costs $400–1,000 depending on size and brand, and lasts 40,000–60,000 km. At 15,000 km/year, expect to replace tyres every 3–4 years.
Annual tyre cost (amortised): $120–300/year
8. Parking and Tolls
- Auckland CBD parking: $5–25/day depending on location
- Wellington parking: $4–20/day
- NZ motorway tolls: Northern Gateway (Auckland) around $3–4 per trip, Tauranga Eastern Link ~$3.50
- Annual parking (commuter): $0 (free parking) to $3,000+ (paid CBD parking)
This cost varies enormously by location and work situation.
Full Annual Cost Model — Three Scenarios
Scenario 1: Cheap Used Car ($8,000 purchase price)
Example: 2012 Toyota Corolla, 130,000 km, purchased outright
| Cost item | Annual amount |
|---|---|
| Depreciation (~6% of $8k) | $480 |
| Insurance (comprehensive) | $700 |
| Registration | $109 |
| WoF + minor repairs | $250 |
| Petrol (13,000 km, 7.5L/100km) | $2,438 |
| Servicing | $500 |
| Tyres (amortised) | $175 |
| Total | $4,652/year ($388/month) |
Note: If you financed this car, add interest cost. If you drive more, petrol climbs.
Scenario 2: Mid-Range Used Car ($18,000 purchase price)
Example: 2018 Mazda CX-5, 60,000 km, purchased with a $10k deposit + $8k personal loan at 10.5%
| Cost item | Annual amount |
|---|---|
| Depreciation (~9% of $18k) | $1,620 |
| Insurance (comprehensive) | $900 |
| Registration | $109 |
| WoF + minor repairs | $150 |
| Petrol (13,000 km, 8.5L/100km) | $2,763 |
| Servicing | $450 |
| Tyres (amortised) | $200 |
| Loan interest (~$8k @ 10.5%, 3yr) | $1,380 |
| Total | $7,572/year ($631/month) |
Scenario 3: Newer Car ($35,000 purchase price)
Example: 2022 Toyota RAV4, 25,000 km, purchased with $10k deposit + $25k loan at 9.5%
| Cost item | Annual amount |
|---|---|
| Depreciation (~12% of $35k) | $4,200 |
| Insurance (comprehensive) | $1,200 |
| Registration | $109 |
| WoF (annual) | $100 |
| Petrol (15,000 km, 8.5L/100km) | $3,188 |
| Servicing | $400 |
| Tyres (amortised) | $250 |
| Loan interest (~$25k @ 9.5%, 5yr) | $2,850 |
| Total | $12,297/year ($1,025/month) |
EV Alternative — Is It Worth It?
Electric vehicles (EVs) have higher purchase prices but substantially lower running costs.
| Cost item | Petrol car | EV equivalent |
|---|---|---|
| Fuel/charging (15,000 km/yr) | ~$3,000 | ~$600–900 |
| Servicing (fewer moving parts) | $400–700 | $150–300 |
| Registration | $109 | $109 |
| WoF | $100 | $100 |
| Insurance | Similar | Similar |
EV running cost saving: $2,000–3,500/year vs petrol, but EVs typically cost $10,000–20,000 more to purchase. The break-even point is typically 5–8 years depending on how much you drive.
Popular NZ EVs: MG4, BYD Atto 3, Nissan Leaf (used), Tesla Model 3. The government EV clean car discount has been reduced since 2023 — check current NZTA clean car programme terms.
Car Affordability Rule of Thumb
A commonly used guide:
- Car value: should not exceed 20% of your annual gross income
- Annual running costs: typically 10–15% of the car’s purchase price
At a $70,000 salary, that means a car value up to $14,000. Annual running costs of $1,400–2,100 (excluding petrol). Add petrol and reality looks more like $4,000–6,000/year total.
