Electricity Price Change

PRICE INFORMATION.

There are different costs that make up your monthly electricity bill. This includes Mercury's charges, as well as those for generation, transmission, distribution, and metering services.

WHY DO PRICES CHANGE?

Each year, all companies along the electricity supply chain review costs and may make changes. We’re adjusting our pricing to reflect these changes to our costs.

Along the supply chain, there are costs to operate, maintain and upgrade critical electricity infrastructure. Critical electricity infrastructure includes the power stations, towers, poles, and lines that deliver electricity to your property. Upgrading critical infrastructure helps ensure you continue to receive a safe and reliable power supply now, and as New Zealand moves to a low emissions future.

CHANGES TO LOW USER PLANS

The Government, with support from the electricity sector, is currently phasing out the Low Fixed Charge Tariff regulations over a 5-year period that started on 1 April 2022. Every 30 cent increase in your daily fixed charge will result in a weekly increase of $2.10 for each year of the phase-out. Removing these regulations will create a fairer, more equitable system in the long-term.

WHEN WILL I SEE THE NEW PRICES ON MY BILL?

Depending on when you receive your bill, you may see your new pricing on your first bill after the effective date. As your prices change, you may see two sets of charges; charges at your old price, and charges at your new price. After this, your bill will appear as normal.

I'M ON A FIXED-TERM AGREEMENT. DOES THE PRICE CHANGE APPLY TO ME?

Some of our fixed-term agreements have set prices for the term of the agreement, and some of them allow for prices to be changed with 30 days notice. If you've received a price change notification, your pricing is subject to change with 30 days notice. For more information, please refer to the Offer Terms for your fixed-term agreement that were sent to you, and our General Terms.

Understanding your Bill charges

In the electricity section of your bill, you can view a breakdown of how your different charge types are calculated based on your prices, usage, and days in your billing period.

Variable charge

The actual electricity you’ve used. This is calculated by multiplying each unit you’ve used (kWh) by your variable price.

Tip: Variable charges depend on the type of electricity meter/s you have at your property e.g. Anytime or Controlled. Find out more about the types of electricity meters.

Daily fixed charge

A fixed amount each day, no matter how much electricity you use. This is calculated by multiplying your daily price (cents) by the number of days in your billing period.
