We supply, service and repair marine diesel engines, generators, gearboxes and steering systems for commercial vessels and pleasure craft, with a specialist marine team ready to work anywhere across New Zealand and the Pacific.

We’ll build a programme around your equipment, your operating environment, and the manufacturer’s recommendations, then make sure it’s delivered on time, every time.
