Builders and contractors are being urged to plan ahead and follow strict safety rules when working near overhead power lines.

Powerco, one of New Zealand’s largest electricity distributors, said in a media release that construction activity too close to power lines, poles and other electricity infrastructure can place workers at risk of electrocution and lead to costly project delays.

The warning was part of the company’s ongoing “building near power lines” health and safety campaign, which aims to raise awareness of minimum safe distances set out under the New Zealand Electrical Code of Practice – NZECP34.

General manager electricity Karen Frew said power lines were commonly found near construction sites, but the dangers of working too close were often underestimated.

“Whether it’s scaffolding, roofing, excavation, traffic management, temporary structures or permanent buildings, work near electricity assets needs to be carefully planned from the outset,” Frew said.

Powerco reminded workers and the public that if they were unsure about the required distance from overhead lines, they should stay at least 4m away.

Structures must remain clear of power lines both underneath and to the side.

Frew said understanding safe distance requirements early could help avoid unnecessary risks and disruptions.

“Planning helps keep people safe and can avoid costly redesigns or delays later. If you’re building or working near power lines, check the requirements before you start.”

Powerco advised anyone planning work near electricity infrastructure – including poles, stay wires and overhead lines – to seek guidance before starting.

Those working within Powerco’s network area can contact the company directly for advice, while projects outside its coverage should be referred to the relevant local electricity lines company.

Further information, including clearance requirements and network maps, is available on Powerco’s website.
