Comparison sites

How we order them: sites that pay us a commission come first and carry the label Partner link. The others pay us nothing and we list them because more choice helps you. Where the regulator runs its own comparison tool, you find it on this page too.

What happens after you click

On the comparison site you enter your address and usage and see plans. Nothing is agreed at this point.
If you decide to switch, the site or power company asks for your name, address, ICP number and email, sometimes a phone number. That is normal: a switch cannot be arranged without them.
The new power company does the rest, including telling your old one. Your power stays on, and if a company approached you uninvited you have 5 working days to cancel.

How to compare power plans honestly in New Zealand

Compare with your real usage and ICP number: Billy and Powerswitch show the plans actually available at your address.
Look at the daily charge and the unit rates together. Low user plans end on 1 April 2027, so low users should compare standard plans now.
Check your current plan for a break fee before leaving a fixed term early.
Time-of-use plans need a smart meter that records half-hourly data; if you do not have one, the new company may charge to install it.
Compare the power part of a bundle on its own: a good broadband deal can hide a poor power price.
Signed up after a cold call or door knock? You have 5 working days to cancel under the Fair Trading Act.

Facts, not promises

How switching works in New Zealand

Switching power company is free and takes 3 to 4 days on average. Your power is not cut off; only the company that bills you changes.
Your new power company arranges the switch. You do not need to contact the old one, but cancel any direct debit to it.
Billy (run by the Electricity Authority) and Powerswitch (run by Consumer NZ) compare plans at your address and can start a switch for you.
If you sign up after a cold call or door knock, you have 5 working days to cancel under the Fair Trading Act. Check fixed-term plans for break fees before leaving early.
Your lines company and its charges stay the same whichever retailer you choose; retailers compete on the energy price, daily charge and service.
If a complaint is not resolved by your retailer, Utilities Disputes handles it for free (0800 22 33 40).

Count the total yearly cost

Not just the price per unit but also the daily charge. With low usage the daily charge can decide, especially after low user plans end in April 2027.

Check the fixed term and break fee

Fixed term, break fees and prompt payment discounts. Set up the contract alert.

Never agree at the door

A real switch starts when you choose it. Never give your ICP number or bank details to someone who knocked on your door or cold-called you.

Common questions

Which comparison site should I use?

Billy and Powerswitch both show the plans at your address and can start a switch. Other sites compare participating power companies. Enter your usage into two of them and compare the results.

What should I have ready?

Your latest bill: last year's usage in kWh, your ICP number, your plan name and daily charge. Half-hourly smart meter data gives the best answer for time-of-use plans.

Is switching safe?

Yes. Your lines company and meter stay the same and the power is not switched off. The new power company arranges the switch, which takes 3 to 4 days on average.

How does Switchly earn money?

If you go to a comparison site through a link marked Partner link and use its service, that site pays us a commission. The service and the price are the same for you. Commission does not influence our articles. It does influence the order on this page: paying partners come first and free alternatives follow.
