Service Lines
What we do
01 UNDERGROUND
Underground Services
Trenching, cable laying, and service connections. We run our own skilled digger crew, meaning you only need to manage one quote and one team on site.

Mains & Switchboards
Consumer unit upgrades and EV readiness. We bring older Waikato and South Auckland housing stock up to modern spec, safely verified and signed off.

Residential Renovations
Kitchen and bathroom extensions. We get the job done properly first time so you can get back to living in your home without the stress.
04 COMMERCIAL
Commercial R&M
Scheduled maintenance contracts and emergency callouts. We'll tell you what needs doing and what doesn't, keeping your site compliant and running.
05 RETAIL
Illuminated Signage
Installation and site repair for high-end retail signage. We ensure your brand remains visible and functional with precision electrical work.
06 TESTING
Compliance Testing
Periodic testing for commercial rentals. Compliant, signed off, and fully tidied up before we leave your premise.

KRIS AND THE COSINE CREW
The crew on the tools. Reliable sparkies, on the day we said.
Kris Goff leads the crew from our home base in Waerenga. With years on the tools across the Waikato and South Auckland, he saw a gap for electricians who turn up when they promise. No excuses, no missing in action.
We don't just pull cables. By having a skilled digger operator on the team, we handle the trenching ourselves for underground runs. That means one team, one quote, and one site visit to get the mains sorted.
You'll find us to be plain-spoken sparkies. We'll tell you what needs doing and what doesn't. Everything is compliant, signed off, and tidied up before we leave. Just reliable service from local tradies.
Kris and the crew turned up exactly when they said they would. No mucking around, just got the job done properly the first time.
