When you plan to work near overhead lines or power poles you must follow the minimum safe distances as set down by New Zealand Electrical Code of Practice - NZECP 34:2001 Electrical Safe Distances.
Follow the four metre rule: All work activity must be kept at least four metres from overhead lines. If you need to work closer to our overhead lines you must get a Close Approach Consent.
You can also arrange to get your power temporarily disconnected, for example if you are going to be working on a roof close to where the power lines connect to the house.
Just call your electricity retailer before you start to arrange a time for a temporary power disconnection (your electricity retailer will tell you if any charges apply). Your electricity retailer will arrange to reconnect your power supply once you have finished working in that area.
