To report a fault call MainPower on 0508 60 70 80.

MainPower regularly completes maintenance and upgrade work on our electricity network. This can result in planned power interruptions. We appreciate that outages are inconvenient; our staff work as quickly and safely as possible to minimise any inconvenience to customers.

MainPower’s electricity network is one of the most reliable in New Zealand, however we do experience unplanned power outages due to a number of reasons. Did you know that one third of MainPower’s fault call outs are caused by trees and branches interfering with power poles and wires, particularly in times of high wind and snow? To find out more see our Trees and Power Lines page.

MainPower’s priority is to maintain continuity of supply and to notify customers of planned interruptions in accordance with our Connection Agreement. When power supply is disrupted, either due to a planned or unplanned interruption or when disconnection is requested by the retailer or an agency other than the customer, every effort is made to ensure human life is not threatened and that legislative and regulatory requirements are met.

Make sure your home and business is prepared to manage power outages – keep a torch and battery radio handy and charge your mobile phone often.

During an outage, or when we have to turn the power off to work on the power lines, generators can be used to run lights and appliances. If you have a generator, please follow general safety guidelines and never use a generator indoors. MainPower can provide advice on what kind of generator is suitable for your situation.

 


Frequently Asked Questions

  • How do I find out about planned power outages?

    If you will be affected by a planned outage, your electricity retailer will send you a letter in advance, so you can make other arrangements.

    Planned outages are also listed on our website, visit the planned outages page.

  • What should I do during a planned power outage?
    • Treat all electric lines as live during the power outage period. Power will be restored as soon as the work is completed which might be earlier than the time specified.  
    • If you have medical support equipment that is dependent on electricity, be ready with your back-up plan to maintain the use of your equipment.
    • Shut off or disconnect all sensitive equipment (computers, televisions etc.) before the outage begins, to reduce the risk of damage from power surges that can occur when power is restored.
    • Minimise the opening of fridge/freezer doors to maintain the temperature. Food will keep for at least one day if seals are in good condition.
    • Turn off any major appliances like washing machines or heat pumps, prior to the outage. This will prevent them from unexpectedly coming on when the power is restored.
    • Make sure all heat-producing appliances (for example, ovens, irons and hair straighteners) are turned off. This will minimise any fire hazard if the power is restored while you’re away.
    • Notify your alarm and phone company as alarm phone systems can be affected.
    • Make sure you know how to override or manually operate security gates and automatic garage doors.
    • If you have a generator, please follow general safety guidelines and never use a generator indoors.
