It's important you're always aware of overhead lines and keep safe when working near them.
If you hit an overhead line there's a real risk of electrocution, explosion, flash over or fire.
If you're going to be working closer than four (4) metres to lines, poles or power boxes, you'll need a close approach consent. This is a legal requirement set down by New Zealand Electrical Code of Practice – NZECP 34:2001 Electrical Safe Distances.
This code of practice:
Pease note, while you're working or building near overhead lines you also need to consider what's below the ground. To avoid damage and risk of electrocution, it's important to know where power or fibre pipes and cables are before you dig. We have a step by step guide on how to safely locate unground pipes and cables before you begin digging. Find out more here.
Please ensure that structures, such as garages and extensions to houses, remain well clear of overhead lines. If a structure is too close to the lines you may need to put the power underground.
Minimum distances allowed between any new buildings and overhead lines have been set by the New Zealand Electrical Code of Practice NZECP 34:2001. Please note that the minimum safe distances will differ depending on the voltage of the overhead lines.
To find out the voltage of the lines that you are planning to build near to, please call 0800 10 40 40.
Please note that any work above an overhead line requires a working near lines consent.
If your works do not comply with Table 2 of NZECP 34:2001 (see below), specialist engineering advice will be required to confirm that the works comply with Table 3 of NZECP 34:2001 (see page 11 of The New Zealand Code of Practice for Electrical Safe Distances).
For specialist engineering advice please call us on 0800 10 40 40.
