About Our Company

It started with an idea…

Gordon Cotter worked locally at the Power Board on the line gang along side Bob Stevens who worked there as a Power Inspector…

Our History


In 1949 Gordon Cotter decided to start a small electrical business and invited Bob Stevens to join him to do the house wiring side, electrical inspections and the like. They called their business Cotter & Stevens.

After a few years the demand for repairs to water pumps became greater in this area and there were no agents in the whole of the Wairarapa to take on this work. Cotter & Stevens were continuosly asked to repair water pumps and this became part of their daily workload.

Not long after, Cotter & Stevens became agents for GANE milking machines. Alfa Laval were looking for local agents to service their milking machines and Cotter & Stevens took on this work as well.

Over the years, the business has grown stronger and the demand for electrical and machinery has expanded with the growth of the region.


We now have a competent staff role of 18 and cover a wide variety of work from commercial and domestic electrical work, water purification and filtration, water pumping and farm water reticulation, farm and domesti irrigation. Milking machine installation, servicing, spares and repairs. Dairy effluent management, design and installation.

We also offer a full after-hours breakdown service.
