100 Airpoints Dollars™

Get 100 bonus Airpoints Dollars™ when you switch to Mercury using promo code 100AIRPOINTS.  Terms apply.

Here are just some of the great reasons to join Mercury:

  • Earn Airpoints Dollars™ when you pay your Mercury bill
  • Get 10% prompt payment discount and save an extra 2% with bills by email, and direct debit
  • GEM, a tool to track your usage, manage and predict your power bill

How accurate is the estimate?

We can give you the most accurate bill estimate when you provide details of your energy usage from a previous bill. If you don't have a bill handy, we use the average of similar households in your area to give you an estimated monthly cost.

Do prices include GST?

Our prices exclude GST as this is the industry standard. However we've included the GST in the total Estimated Costs figure to give you a better idea of your total bill.

For more information on what makes up our prices, see here.

What's included in this plan?

The current plan is based on our best rates with no contract.

What's the difference between standard and low energy users?

Low energy users tend to use fewer than 8000 kWh per year and typically only have 1-3 people at home - or are really energy efficient! Standard energy users usually use 8000+ kWh per year and usually have 4+ people at home - or there might be some energy hungry items at home.

Can I get gas?

Mercury offers mains piped gas together with electricity on a dual fuel discount of 15c/day. The summer and winter estimations in this form do not include this discount - this will be applied when the sign up process is complete.

Piped Gas is only available in the North Island. We do not offer LPG or gas only plans at this time.

Can I edit my information after signing up?

Yep! If you have entered incorrect information by mistake you don't have to complete this form again. Simply reply to your confirmation email and we'll update your details for you. Or, as soon as your switch is complete (usually within 2 weeks) you will be able to log into My Account to check and edit your details as needed.

Can I earn Airpoints Dollars™ on my monthly bill?

Yes, you can earn Airpoints Dollars™ on both your electricity and gas spend each month. For more information read our Airpoints™ FAQs.
