Working safely around electricity
Whether at work or play, always look out for power lines
Electricity can ‘jump’ from power lines, so getting yourself or equipment too close to power lines can cause property damage, serious injury or death. Read on for information about staying safe around power lines.

Working near power lines
If you are working around power lines, you will need to follow several key rules which are laid out in the New Zealand Electrical Code of Practice for Electrical Safe Distances (NZECP 34:2001).
5.2.1 The distance between any live overhead electric line and any part of any mobile plant or load carried shall be “AT LEAST 4.0 METRES”, unless the operator has received written consent from the overhead electric line owner allowing a reduced distance.
5.3.1 Mobile plant or any load carried shall not operate above the conductors of any overhead electric line unless the operator has received written consent from the overhead electric line owner to work above the overhead electric line.
Working near underground cables
Getting a clear picture of where underground cables are located is essential for staying safe and preventing damage to the network. Click here to learn more about working near underground cables.

Accidents involving electricity
Vehicle or mobile plant accidents involving electricity
If you are outside the vehicle:
- Stay clear of power lines (at least 10 metres).
- Warn others of the danger.
- Call 111 for assistance.
If you are inside the vehicle:
- If you can do so safely, carefully drive to a safe distance from all electrical hazards before exiting the vehicle.
- Call 111 for assistance.
- The safest thing you can do is stay in your vehicle until emergency crews arrive to assist you.
- If the vehicle cannot move for any reason and you need to exit the vehicle because of a life-threatening danger (such as fire), jump as far away as you can, keeping both feet together when you land. Continue to jump until you reach safety. This video includes a demonstration of what to do in this situation.
Aircraft safety – wire strike
Any aircraft flying below 500 ft is at risk of a wire strike, but helicopters are especially susceptible due to the nature of the work they do. Wire strike is preventable, but only with a well-planned safety programme to identify hazards and put mitigations in place. For more information on wire strike, visit the CAA website.
Boating safety
Boat operators should ensure they are always aware of power lines and cables while on the water and at boat ramps. Always remember to:
- Look for signs which make the location of underwater cables before dropping anchor.
- Remain vigilant for overhead power lines if your boat has a mast.
- Lower your mast at the boat ramp before heading home.
