Truck Workshop at Thwaites

Although Thwaites are fully authorised Isuzu truck and bus service agents, it’s not uncommon to see other brands being serviced in our well-equipped Nelson workshop. We also offer servicing and repairs for motorhomes and campervans, our workshop in Nelson is all set up for all RV repairs and servicing.

Since 1998 we have built a loyal following of clientele and although the type of fleet may change within Thwaites broad client base, the commitment to service regardless of make and model has ensured relationships have remained solid.

We understand a truck off the road is lost revenue and our commitment to afterhours servicing, continual improvements with updating service equipment and ongoing specialised training of staff is what has made Thwaites a popular choice in heavy vehicle repairs in the top of the south region.

What sets Thwaites apart?

Experience: Thwaites staff have a vast amount of experience in truck maintenance, repairs and servicing with key personal working in the industry for over 40 years. We know the biggest frustration fleet managers and vehicle owners experience in the servicing industry is a lack of knowledge.

Although staff training is paramount Graeme and Bernie are the back-up to the service team, the chances are they have experienced first-hand even the obscure mechanical issues encountered in machinery servicing are very high.

Menu servicing: Fixed cost servicing is available on most vehicles. This extends further than an “A” or “B” service, this means set amounts for an oil/filter service regardless of make – ideal for a mixed fleet.

Size doesn’t matter: We can handle machinery from utes and vans to a 50-tonne truck and trailer unit.

Dedicated service vehicles: We’re equipped to come to you, wherever, whenever.

Specialised brake servicing: We have modern brake testing equipment and on-site certified brake examination capability.

Hydraulics: Thwaites has extensive expertise in the hydraulics field. As part of the one-stop shop policy, they diagnose hydraulic issues and repair faults. We have mechanical staff experienced in the hydraulics field that are active in the field and after hours workshop repairs. 

We also specialise in auto electrical and air conditioning repairs.

Isuzu parts and servicing

Being appointed as a service agent for a reputable brand such as Isuzu is not a decision a manufacturer makes on a whim.

There are many considerations to take into account; the infrastructure the business can devote to the brand, the depth of experience within the team, the commitment to parts stock and management and the devotion to ongoing training.
