Does servicing at an independent workshop void your warranty?
Servicing at an independent workshop does not automatically void a warranty. Here is what the Motor Trade Association says, and what records to keep.
Read article →The short answer
Follow the schedule in your owner's handbook, which sets service intervals by time and distance, whichever comes first. Many manufacturers suggest roughly once a year for everyday driving. Heavy use, short trips, towing, dusty roads and older vehicles with no service history can justify servicing sooner, and electric vehicles still need a regular check.
There is no single service interval for every car. A new petrol hatchback, a hard-working diesel ute and an electric SUV all have different needs, and the right answer is written in the handbook for your particular vehicle. Here is how to work it out, and how to tell when sooner is smarter.
Start with the manufacturer's schedule
Your owner's handbook or service book sets a schedule, normally in months and kilometres, such as every 12 months or 15,000 km, whichever comes first. Both limits matter. Low-mileage cars still need servicing on time, because oil degrades, rubber ages and fluids absorb moisture whether or not the odometer moves.
Many manufacturers suggest roughly one service a year for typical driving. Some set longer or shorter intervals, and the type of service can alternate (a minor service one year, a major service the next). If you do not have the handbook, tell us the make, model, year and rego and we can work out the schedule.
When to service sooner
Schedules often have a "severe" or "heavy-use" category, and plenty of New Zealand driving falls into it. Consider servicing sooner if your driving involves:
- Lots of short trips where the engine rarely warms up fully.
- Stop-start city traffic, which is hard on engines, brakes and transmissions.
- Towing or carrying heavy loads, including work utes and vans.
- Dusty, muddy or salty conditions, which clog filters and corrode parts.
- Hot or cold extremes and long idling.
Petrol, diesel, hybrid and electric
Petrol and diesel engines depend on clean oil and filters. Diesels, especially in commercial use, often benefit from careful attention to oil and fuel filters. Hybrids have a conventional engine, so they need engine servicing too, plus checks on the hybrid system and brakes. Electric vehicles have no engine oil to change, but they still need brake fluid, coolant, cabin filters, tyres, suspension and the 12V battery looked at; see Do electric cars need servicing?
Used, imported or no history?
If you have just bought a used car, particularly an import with an unknown history, assume the main service items are due until you can prove otherwise. A baseline service resets the clock: fresh oil and filters, fluids checked and the safety items inspected. If the engine has a timing belt, find out when it was last replaced. See engine and cam belt work.
Service versus WOF
A WOF and a service are different things, and passing one does not mean you can skip the other. A WOF is a pass-or-fail safety check on the day. A service is maintenance that keeps the vehicle reliable. With WOF intervals getting longer for many newer vehicles from November 2026, regular servicing becomes the main thing between you and a failed inspection. See the WOF changes explained.
Signs you should not wait
- A warning light on the dashboard. See what warning lights mean.
- New noises, vibrations or a pull when braking or steering.
- Oil, coolant or other fluid on the ground under the car.
- Hard starting, rough running or a drop in fuel economy or EV range.
Frequently asked questions
Is it once a year or every 10,000 km?
Whichever your manufacturer specifies, and usually whichever limit you reach first. Many suggest about once a year for everyday driving, but the handbook for your vehicle is the authority.
Does a low-kilometre car still need a yearly service?
Yes. Oil, brake fluid and coolant age with time as well as distance, and rubber parts perish. Time-based intervals exist for exactly that reason.
How often should an electric car be serviced?
Follow the manufacturer's schedule, which is commonly about yearly. Even with a long interval, a yearly check of brakes, tyres, suspension, coolant and the 12V battery is worth doing.
What if my car has no service history?
Treat the main items as due and book a baseline service. We will inspect the car, replace what is needed and tell you what to expect next.
