If your business is running 2020 or 2021 utes and trucks, you're likely approaching a decision point — and the numbers are shifting faster than most business owners realise. This isn't about buying new for the sake of it. It's about understanding the real cost of holding on, and whether 2026 is the right moment to act.
The hidden cost of keeping older vehicles
Most business owners think of vehicle costs in simple terms: registration, WOF, fuel, insurance. But once a commercial ute or truck crosses the 150,000km or five-year mark, a different set of costs starts showing up — and they're harder to budget for.
Total Cost of Ownership (TCO) is the number fleet managers and operators use to measure the real cost of a vehicle over its life. It includes:
Total Cost of Ownership — what it actually includes
The first three years of a commercial vehicle's life are typically the cheapest to operate. After year five, repair costs tend to increase sharply — often just as the vehicle's resale value is declining fastest. That squeeze between rising costs and falling asset value is the financial crossroads most fleet operators hit around 2025–2026 with vehicles bought in 2020–2021.
A rough way to test your own position: add up what you've spent on repairs and unplanned maintenance on your oldest ute or truck in the last 12 months. If it's approaching 15–20% of the vehicle's current market value, you're likely past the point where holding makes financial sense.
The 2026 IRD Investment Boost — what it actually means for vehicle upgrades
From 22 May 2025, IRD introduced an Investment Boost allowing NZ businesses to immediately deduct 20% of the cost of new assets as an upfront expense. Standard depreciation then applies to the remaining 80%.
In practical terms, if you finance a new $60,000 ute (ex. GST):
- You claim 20% ($12,000) as an immediate expense in the year of purchase
- Standard depreciation continues on the remaining $48,000
- This brings forward a significant tax deduction into year one, reducing your taxable income now rather than spreading it over the asset's life
This applies to new assets first available for use on or after 22 May 2025. Second-hand assets don't qualify. Always talk to your accountant before making a purchasing decision based on tax incentives. Read our full Investment Boost guide →
Resale value: why timing matters more than you think
Vehicle values in New Zealand have been through an unusual cycle. The supply disruptions of 2020–2022 pushed used vehicle prices higher than normal. That inflated value has been gradually deflating as supply normalises — meaning 2020–2021 vehicles that may have held their value well in 2022 and 2023 are now declining faster.
If you're planning to upgrade anyway, capturing your vehicle's resale value before it falls further is a real consideration. The difference between trading a 2020 Ford Ranger with 120,000km today versus in 18 months could be $5,000–$8,000 in trade value — that's effectively a larger deposit on your next vehicle finance deal.
The fuel efficiency argument
Ute and truck technology has moved quickly over the past five years. The gap in fuel efficiency between a 2020 model and a 2025/2026 equivalent — particularly in diesel engines and hybrid-assist systems — is meaningful for businesses clocking up high kilometres.
For a tradie or fleet operator doing 40,000+ km per year, even a 10–15% improvement in fuel efficiency adds up. At current diesel prices, that could represent $2,000–$4,000 per vehicle per year in savings — before you factor in the difference in servicing intervals on newer engine technology.
Downtime is the cost nobody budgets for
Of all the costs in the TCO calculation, unplanned downtime is the most damaging and the hardest to recover. A ute in the workshop for two days isn't just costing you the repair bill — it's costing you the work that didn't get done, the subcontractor you had to call in, or the job you had to push back.
Newer vehicles come with manufacturer warranties and longer service intervals. An older vehicle out of warranty is fully your risk. For sole operators or small trades businesses where one vehicle going down genuinely disrupts the whole operation, the case for keeping a newer, warranted vehicle is particularly strong.
