On 8 October 2026, the rules for building near overhead power lines changed. The amended National Environmental Standards for Electricity Network Activities (NES ENA) now cover distribution lines, the poles and wires that run along most Auckland streets. Since then, almost every live job we have has needed a clearance check, engagement with Vector and, in some cases, an external report.
Distribution Lines Had No National Rules
The 2009 standard covered Transpower’s national grid only. Distribution lines, which supply streets and individual properties, had no national direction at all. Each council dealt with them in its own way, and many didn’t deal with them.
The safe distances themselves have always existed. The New Zealand Electrical Code of Practice for Electrical Safe Distances (NZECP 34:2001) sets the minimum clearances between conductors and buildings, structures and earthworks. It’s mandatory under the Electricity Act 1992 and applies whether or not you hold a resource or building consent.
It is a safety code, though, not a planning instrument. The Ministry for the Environment’s own analysis accepts that developers and councils are often unaware of it, that building too close to lines remains a problem, and that subdivision can’t be managed through the code at all.
The NES ENA closes that gap by making the NZECP 34 distances a resource consent matter.
What This Means
Any development on a street that has overhead powerlines and power poles is where this is most relevant. A typical site has a pole on the street frontage, and a service line to the existing house. Because the building trigger is 30m, a pole outside the site or even powerlines across the street can put much of the site inside the rule.
Scaffolding is treated as a structure under NZECP 34. Vector’s published guidance requires a scaffold platform near its lines to have 450mm of clear access, and it won’t de-energise lines to help build a new building. A building can pass in its finished form and still fail during construction because of scaffolding.
Excavation and conductive fencing close to a pole can also need a close approach consent from the line owner before work starts.
Why Early Assessment Matters
A few years ago we had a project where the clearances couldn’t be achieved, and a s127 variation was needed to resolve it. That is the cost of finding the constraint after the design is fixed: more processing time, more cost, and a client who has already committed to a layout.
At a high level the change is sound. It highlights clearances part of the design from the start, rather than something found at building consent or on site.
How We’re Handling It
We’ve built the new requirements into our survey process so the information is available from the start. We identify the poles and lines near the site, obtain the line owner’s information, survey the required detail and provide guidance to the design team. We manage the communication with Vector and cover the required assessments in the resource consent application.
The rules are new to councils as well, and everyone is refining their process as they go. We’d rather have the assessment on file than rely on one reading of the rules holding up.
What To Do Now
Check every site for poles and overhead lines before the layout is fixed, including the street frontage and anything within 30m of where you plan to build. Get the clearance information before the design team commits to a building position. Allow time in the programme for engagement with the line owner. If a clearance can’t be met, find out early whether the answer is a design change or a change to the line itself.
