Everything you should know about commercial vehicles & fleet servicing
A workshop perspective on what's involved, how we run the job, and what shapes the final cost.
Why commercial vehicle servicing in Hamilton needs to be different
A delivery van turning over short trips around Frankton and Te Rapa wears differently to a private SUV that does the school run twice a day. Trades utes carrying gear out to Cambridge and Morrinsville sites sit harder on their brakes, run higher on their springs, and load up their DPFs in ways that show up in the workshop, not in the owner's manual.
When your vehicle is the business, servicing has to do two jobs: keep the mechanicals right, and keep the vehicle off the hoist as much as possible. That means accurate diagnostics on the first visit, parts sourced quickly, and a workshop that knows how to prioritise a fleet job. We have serviced light commercials, vans, utes and light trucks up to 6,000 kg GVM from our Kahikatea Drive workshop for over twenty years, with authorised Bosch, Delphi and Garrett training behind the diesel side and an MTA-aligned standard across the rest. Medium rigid trucks above that weight run a Certificate of Fitness and sit on our Class 2 truck servicing page.
What our commercial vehicle servicing covers
A scheduled commercial service starts with the basics done properly: engine oil to manufacturer spec, OEM-spec oil and air filters, fuel filter (critical on common rail diesels), sump plug washer renewed, and a full multi-point inspection. From there it depends on the vehicle and its duty cycle.
For diesel work vans and utes, including the Toyota Hiace, Ford Transit, Hilux, Ranger, BT-50, Triton and D-Max, we use manufacturer-level scan tools to pull live data from the engine and transmission. We check rail pressure against expected values, watch DPF differential pressure under load, and verify EGR behaviour. Suspect injectors come out and go onto a calibrated bench for flow testing, and the same applies to high-pressure pumps. Failed components are sent to our specialist partners for rebuild where that is economical, or replaced with Bosch or Delphi reman units.
Garrett turbochargers are inspected for shaft play, oil return condition, and actuator function. Variable-geometry turbo (VGT) faults are common on hard-worked delivery and trade vehicles, and we calibrate the actuator to manufacturer spec rather than simply clearing the fault.
Brakes are inspected against load-rated specifications. Suspension components, including bushes, ball joints, leaf packs and sway bar links, are checked for wear that a private car would never show. Tyres are assessed for trade wear patterns: scrubbing on a courier van, edge wear on an overloaded ute, uneven wear from a worn front end. WOF-relevant items are flagged and dealt with before the inspection.
How a commercial servicing job runs at our Frankton workshop
You book the vehicle in, either as part of a held fleet slot or as a one-off. On arrival we open a job card with the vehicle's history, current odometer, and the brief. The vehicle goes onto a hoist and the scheduled service runs through: oil, filters, fluids, multi-point inspection, brake measurement, tyre check. The diesel side gets scanned for fault codes and live data. Anything outside the scheduled scope is quoted before we touch it.
When parts have to come out, injectors, pumps or turbos, they go to our fuel injection test room for bench testing on calibrated equipment. The data decides whether a unit is rebuilt by our specialist partners or replaced. After refit, the vehicle is road tested against manufacturer specs, and you get a written summary of work done plus what is flagged for next service.
What affects the cost
Commercial servicing cost varies more than a passenger car. The main drivers are:
- Specific vehicle needs - a Hilux service is straightforward; injector access on a tight-packed delivery van is several hours of labour before any parts touch the bench
- Duty cycle - a fleet van with carbon build-up needs more clean-up than a low-km private ute
- Parts availability - genuine Bosch and Delphi lead times can stretch on less common platforms
- Scope - one injector versus a full set is a different job; a leaking water pump or worn ball joint found during inspection is quoted and agreed before the work happens
- Diagnostic time - a scheduled service is quick; a complaint-based diagnosis adds time
For fleet contracts, we can group routine items by vehicle type and budget. For a quote on your vehicle, call (07) 847 3339 or use the contact form.
Hamilton and Waikato fleet coverage
Our commercial customers come from across the Waikato. Trade businesses from Cambridge and Te Awamutu drop off utes for logbook services. Courier and delivery vans from Hamilton's CBD and the airport corridor cycle through on scheduled maintenance. Owner-drivers from Morrinsville, Huntly, Ngaruawahia, and Raglan use us for WOF prep and diesel injection work.
Whether you are an owner-driver with one ute or running a small fleet, the Frankton workshop has the space, the tooling, and the diesel expertise to keep your vehicles working.

Common Questions
Everything you might want to know before booking.
How often should a commercial vehicle be serviced in New Zealand?
Manufacturer intervals are typically every 10,000 to 15,000 km or 12 months, whichever comes first. Heavy-use fleets, couriers, trades on rural roads, vehicles towing, should be serviced more often. We'll set an interval that matches how you actually use the vehicle, not just the book.
What's the difference between a WOF and a CoF?
A WOF (Warrant of Fitness) covers light vehicles up to 6,000 kg GVM, including most utes, vans and light commercials, and is usually inspected yearly. A CoF (Certificate of Fitness) covers heavier vehicles, including Class 2 medium rigid trucks, and is inspected every six months. The light commercials we service on this page run a WOF. For Class 2 trucks above 6,000 kg, see our Class 2 truck servicing page.
What size and type of commercial vehicles do you service?
On this page we cover light commercial vehicles up to 6,000 kg GVM, vans like the Hiace and Transit, utes like the Hilux, Ranger, BT-50, Triton and D-Max, and light trucks in that weight band. For medium rigid trucks above 6,000 kg, Hino, Isuzu, Fuso and UD, see our Class 2 truck servicing page. We don't handle Class 4 articulated rigs.
Do you work on common rail diesel fuel injection?
Yes, it's a core part of what we do. We're authorised agents for Bosch and Delphi, so we have the factory training, test benches, and service data to flow test and calibrate common rail injectors and high-pressure pumps used across most NZ commercial diesels in our fuel injection test room. Units that need rebuilding go to our specialist partners, or we fit remanufactured replacements.
Can you handle DPF and EGR problems on delivery vans?
Yes. Vans run on short urban delivery cycles often can't get the DPF hot enough to passively regenerate, which leads to differential pressure faults, limp mode, and EGR carbon build-up. We diagnose with live data, run forced regenerations where appropriate, and clean or replace where the DPF has reached end-of-life.
Do you offer fleet service contracts?
Yes. We work with Hamilton and Waikato businesses on scheduled servicing plans, scaled to vehicle count, type, and run hours. We hold service windows so your fleet cycles through with minimal disruption. Phone us with your vehicle list and we'll put together an arrangement.
How quickly can you fit a vehicle in for emergency repair?
For fleet customers we hold service windows and prioritise emergency work. For one-off urgent jobs, phone us first thing, we'll fit you in where we can. Diesel injection faults that throw a vehicle into limp mode are usually triaged within 24 hours.
What does a WOF pre-check involve?
Before a light commercial goes for its Warrant of Fitness, we work through the inspection items, brakes, steering, suspension, tyres, lights, wipers, body and chassis condition, glazing and seatbelts. Anything that won't pass is flagged and repaired first, so the vehicle clears its WOF without a re-inspection. It's the practical way to keep a work van or ute legal and on the road.
Can you work on Japanese commercial diesels like Toyota, Mazda and Mitsubishi?
Yes. Japanese diesels are the backbone of the NZ light commercial fleet. Hiace, Hilux, Triton, BT-50, D-Max and the diesel van and ute platforms, we have the tooling, scan equipment and parts access to service and repair these properly, including the common rail injection and turbo systems behind most of them.
What affects the cost of commercial vehicle servicing?
Mostly: vehicle class (light vs heavy), the labour required for the specific job (e.g. injector access on a tight-packed van is harder than on a Hilux), parts availability (genuine vs aftermarket vs reman), severity of any fault found, and diagnostic time if the vehicle came in with a complaint rather than a scheduled service. We quote up front before any work beyond the scheduled service.
Do you do pre-purchase inspections on used commercial vehicles?
Yes. If you're buying a used ute, van, or light truck, we'll inspect engine, drivetrain, brakes, chassis, and diesel injection condition, do a scan for stored fault codes, and give you a written summary. It's the cheapest insurance against buying someone else's problem.
Are you MTA-aligned and WINZ-approved?
Yes. We work to MTA-aligned standards and we're WINZ-approved for repair quotes. Both matter for fleet operators who need accountability on workmanship and for customers needing documented quotes for funding.
