On site when the frame's ready. Every stage, on time.
The new build problem
- A builder needs a crew that turns up the day the frame's ready, hits the stages, and doesn't stall the rest of the trades.
- An owner needs the powerpoints where they'll actually use them, not where the standard layout dumps them.
- A build that stalls while everyone waits on the wiring.
We turn up, we plan it around how you'll live, and we keep the build moving.
One crew from pre-wire to handover. On the programme, every stage signed off, and your builder never has to chase us.
Staged around the build, not around us.
Give us a call
You or your builder. Tell us the job and the programme.
Walk the plans
We go through the plans with you, work out where power, lighting and data should go, and provision for what's coming later.
Clear quote, no surprises
A fixed price for the full fit-out, spelled out. Materials, labour, stages, all in.
Pre-wire, on time
We turn up when the frame's ready and run clean cable that passes inspection first time. Cable boxed, labelled, photographed before lining.
Fit-off and certify
Switches, powerpoints and the switchboard fitted after linings and finishes. Every circuit tested and signed off before handover, paperwork with the keys.
What we do.
Full electrical fit-out from pre-wire to handover.
- Full pre-wire, fit-off and switchboard on new homes
- Layout walked with the owner or architect before the gib goes up
- Provision for heat pumps, EV chargers, solar built in now
- Data cabling and network points
- Working in step with your builder and other trades
- Turn up when the build needs us, so it keeps moving
- Certified before handover, with paperwork for insurance and resale
Builders rebook us. That's the tell.
We slot into the programme, hit the stages, and keep the job moving.
We work in with local builders across Whanganui, and they bring us back because we hit our stages and don't hold the job up. Whether it's your own home, a spec build or a small development, we slot into the programme and keep it moving.

What builders and owners ask us.
Will you hold up my build?
No. Builders rebook us precisely because we turn up when we say and hit our stages. We slot into the programme and keep the other trades moving, not the other way round.
Can I plan for a heat pump, EV charger or solar now?
Yes. Better to provision now than retrofit later. We build in the cabling, the board capacity and the circuits for future loads at pre-wire, so adding them later is a fit-off job, not a rewire.
Do you work with my builder or do I organise it?
Either. Your builder can bring us in, or you can. Once we're on the job we deal with the builder direct so you're not managing the coordination.
