What We Do

NETcon is an industry leader when it comes to operating and maintaining electricity networks in the South Canterbury region. We look after a dynamic network that covers the area between the Rangitata and Waitaki Rivers, from the coast inland to Mount Cook.

It’s an environment that often requires innovative thinking to meet some tough challenges, but we are an ambitious organisation with a focus on continuing to be the best in all we do!

We’re based in the spectacular town of Timaru, a truly beautiful part of the country, with seriously mint views of snow-capped mountains on one side and the scenic Caroline Bay on the other.

With pure dedication to providing superior service, clients can consistently expect a solid commitment to quality work, on time and on budget. We pride ourselves on being able to provide tailored solutions every time. 

Alpine Energy is one of NETcon’s major clients and our experienced technicians, line engineers and electricians provide the expertise required to operate and maintain Alpine's electrical distribution infrastructure, including a variety of essential plant and equipment. Our priority is to provide a safe and reliable electricity network through construction, maintenance and vegetation management services.
