We like to reward our customers with something a little more wonderful when they join Mercury on an Open Term, 1 year fixed price offer. Lots of words, we know! But here's everything you need to know about the Offer. Grab a cup of tea and have a read!


  1. This offer is available to:
    1. non-Mercury residential customers in the Christchurch network area who join us ("Joiners"); and
    2. sign up for electricity on a 1 year fixed price offer and are accepted as a Mercury customer in accordance with Mercury's standard terms and conditions.

Your Fixed Price Offer

  1. By taking up this Offer, you will receive a discount on your electricity. By this, we mean you'll unlock a discount on Mercury's standard headline rates for your daily fixed and variable/inclusive usage charges for electricity. For the avoidance of doubt, the discount won't apply to the Electricity Authority levy, GST, or any special or service charges.

  2. Your discount is available for 1 year from the date we accept you as a Mercury customer ("Offer Period"), as long as you remain a Mercury customer on this offer.

  3. You will revert to standard Mercury prices at the end of the Offer Period, unless Mercury offers you, and you accept, a new fixed price offer before the end of the Offer Period.

  4. This offer is Open Term meaning no Early Termination Fee will apply if you cancel your fixed price offer in line with our Standard Terms and conditions during the Offer Period.

  5. If you move property during the Offer Period, please contact us before you move and:
    1. You can take your fixed price plan with you so long as your move is within the same network and your new property has the same meter type; or
    2. If we are unable to transfer your fixed price offer to your new address, you will be transferred to standard Mercury prices.
  1. Your fixed prices are based on your current meter type.
    1. If your meter type changes, where possible, we will put you on the fixed price offer for your new meter.
    2. If your current meter set up is incorrect, we will place you on the correct pricing plan that matches your meter.
  1. The fixed price offer does not include GST, and any of the Mercury Service Fees. Any subsequent change to the NZ Government GST rate, and Mercury Service Fees within the Fixed Price Term will apply.
  1. If you choose to move to a plan that includes solar generation rates for electricity during the Offer Period:
    1. Your fixed price offer will automatically be terminated; and
    2. Your electricity supply will be moved to standard Mercury prices.
  1. Please note that while the rates for individual parts of your fixed price may change, we will make sure the total price remains fixed in line with this plan.
  1. Unless we tell you otherwise, you cannot combine this offer or pricing plan with any other Mercury offer or pricing plan.
  2. The Offer is not transferable or redeemable for cash.
