COF Pre-Checks & WOF Checks,
Auckland
Silverdale Mechanical Engineering carries out thorough pre-inspection checks designed to give your vehicle its best chance of passing the official inspection — first time, with no nasty surprises.
Two inspections apply in New Zealand. The Certificate of Fitness (COF) is the inspection for heavy vehicles — including trucks, buses, coaches and other heavy vehicles — while the Warrant of Fitness (WOF) applies to light vehicles such as cars, SUVs, vans and utes. Our workshop knows the difference, and we check the right things for the right vehicle class.
Our mechanics inspect and rectify issues before you go for the official COF or WOF, covering brakes, safety systems, steering and suspension, lights and the other common causes of failed inspections. It's a straightforward way to avoid wasted inspection fees and repeated trips.

Vehicle WOF Checks
COF pre-checks are a speciality of our workshop. As heavy vehicle specialists we service trucks, buses, coaches and plant machinery every day, so we know exactly what an inspecting officer looks for — brakes, steering, suspension, chassis condition, lights, tyres and safety equipment.
For WOF checks we apply the same thorough approach to cars, SUVs, vans and utes — including the motorhomes and camper vans we service regularly. Whether your vehicle is a heavy truck heading for its COF or a family car due for its WOF, our pre-check helps prevent a fail and keeps your vehicle safe and compliant.
Where issues are found, we can quote and rectify them in our Silverdale workshop — often before the official inspection — so you head to the testing station with confidence.
