Building near power lines
Roofing, scaffolding and building
Whether you’re a property developer, surveyor, builder, scaffolder, roofer – or even just putting up a fence, sign, a marquee or laying a driveway – it’s important to know the rules around building near power lines.
From design through to construction, you must follow the minimum safe distances from power lines set out in the NZ Code of Practice (NZECP34 – Electrical Safe Distances).

What NZECP34 – Electrical Safe Distances covers
The code covers all types of building and excavation – permanent or temporary – near power poles and lines, including but not exclusive to:
- Portable buildings and marquees
- Using scaffolding
- Building fences
- Digging/laying a driveway
- Raising ground levels
- Erecting signs
- Artificial shelter belts and canopies
All work must be a safe distance away from overhead lines.
The minimum distance between a structure and an overhead line varies depending on the voltage the line is carrying.
The structure needs to be clear of lines both underneath and to the side.
