About us

Our business has been providing motor services in Auckland for over 35 years and has built a reputation for expertise in vehicle repairs. We are committed to serving the best interests of our customers through sound advice, reliable workmanship and fair pricing. Based in Onehunga, we provide general mechanical services, as well as specialist services for diesel engines and vehicle air-conditioning systems.

We receive diesel work from customers around the Greater Auckland region and beyond, and are also used regularly by other non-specialist garages to assist with diesel work. We are MTA assured, giving you protection and peace of mind that high standards of professional service are maintained and monitored. We therefore subscribe to all MTA policies and practices and our work is fully guaranteed. Our customer service programme is under constant development as we seek to further improve the services we offer, and to this end we actively seek and welcome feedback from our customers. Morrison is owned and managed by the husband and wife team of Miles and Rachel Crellin

Whether you are travelling around town, off-road, or to the far end of the country our goal is to get you there safely and reliably. Please call us today for obligation free advice and estimates - the team at Morrison look forward to assisting you with the repair and maintenance of your vehicle.



    Our business and family vehicles have been faithfully serviced by the team at Morrisons for the last nine years. The service and quality of diagnosis is second-to-none which is why we travel from West Auckland to have them perform even everyday tasks.  My wife and daughter have also found the honesty and integrity of the staff gives them complete confidence when they're advised of a needed repair that has been diagnosed during a regular service. The recent move to their new, larger facility has been a major upgrade and we highly recommend this business

    I just wanted to tell you how happy we are with the excellent service we get from Morrison Diesel. Our 2006 Ford Transit motorhome now sings like a bird. I love the way Miles takes care to diagnose the problem, how he explains the best way to tackle our maintenance issues and is ably assisted by the capable Rachel. We don't live nearby, but it's worth crossing town to get the sort of service and technical skills that Miles has.

    We are a local business based in Onehunga and have been using Morrison Diesel Specialists for many years. Their servicing & mechanical support on our vehicle fleet has been fantastic and is vital in keeping our trucks on the road. Prompt communication and same day turn around on work is what keeps us coming back. From all the team here at Won-Door New Zealand we thank you very much.

    Excellent mechanics with petrol motors as well as diesel. Have looked after our family for several years and their service has always been top grade. I highly recommend them as a company that goes beyond the usual in order to look after their customers. Thanks for looking after our cars.
