Electrical projects

built to run your operation, not just switch it on

From hazardous area wiring to EV charging infrastructure, We deliver electrical project work for Waikato's commercial and industrial operators, and stay on as your long-term electrical partner once the job is done.

What we do
Hennessy handles the full range of electrical project work for commercial and industrial sites: hazardous area wiring, EV charger installation, general electrical installation, and brownfields or greenfields builds. We work on live industrial sites, new builds, and everything in between, for clients who need the job done right the first time and a team they can call again next time.

How our process works

Step 1 - Scope

We visit your site, understand your operation, and map out the electrical requirements against your production schedule, safety requirements, and budget.

Step 2 - Design

Our team designs the electrical solution around your site constraints, whether that's a hazardous area, a live production line, or a new build from the ground up.

Step 3 - Install

We deliver the project with qualified, EWRB registered electricians, working to minimise disruption to your operation.

Step 4 - Support

We don't disappear after commissioning. Hennessy stays on as part of your operational team, ready for the next project, maintenance call, or expansion.

Proof in the field:
Waitoa Protein Plant

When Waitoa Natural Proteins needed a full electrical build for their new greenfield protein plant, they brought Hennessy on for the long haul, not a single job. Over 36 months, our team delivered the complete electrical scope: switchboards, motor control centres, safety systems, and power distribution for a 24/7 industrial facility.

"The team at Waitoa has been impressed by the sheer quantity of electricians we have on the project to deliver the expertise required, and the 'can do' attitude of our team as we have been able to accommodate all of their design changes to date." - Glen Loft
