Important information for Z Energy customers

From 22 July 2025, Z Energy becomes part of the Meridian Energy whānau. We’re currently working hard in the background to match you with a plan that suits your situation. Once this has been confirmed you will receive an email from us with your new pricing and plan. In the meantime, you'll remain on your current rate with Z Energy. 

We’ll begin moving Z Energy customers over to Meridian from 22 July 2025. There are quite a few of you, so we’ll be doing this in stages to make sure everything goes smoothly. Before your power plan is switched to Meridian, we’ll send you an email with your new rates and the plan we’ve matched you to, so you’ll always be across what’s happening.

No, we are taking care of it all in the background. You'll receive an email in the coming weeks from Meridian letting you know what your new plan is. Once you’ve received this, you’ll also get a welcome email from Meridian letting you know your account has been switched over.

Yes, you can move to another retailer at any time.

You’ll get a welcome email from Meridian once your account has been transferred. This email will include your new account number. Until then, your power supply will remain with Z Energy. You don’t need to do anything, we’re handling the switch for you.

We’re taking the time to match you with a plan that best suits your needs. If you’re not happy with the plan that we have chosen for you once the switch to Meridian is complete, our team of energy experts is here to help. Just have your account number handy, it’ll be in your welcome email and we’ll work with you to find a better fit.

Your account will move no sooner than 12 business days after receiving your transition email. You’ll get a welcome email confirming the switch date and your new Meridian account number. 

You’ll receive a welcome email when your move to Meridian is complete. This will likely be within 12-25 working days of receiving your plan detail email.

Not at all. Your electricity supply will continue as usual during the transition.

Once your account transfers to Meridian, your Z Energy contract ends and Meridian’s terms and conditions will apply. You’ll receive at least 12 business days' notice before the change takes effect.

It’s likely because our records show you have more than one property or ICP with Z Energy. Each property is treated separately, so you’ll receive a separate email for each one. 

If you think this might be a mistake, please get in touch — we’ll be happy to check it out for you. 

We appreciate your proactiveness but for now there’s nothing you need to do, we are taking care of it all for you in the background and you will receive an email once your move is complete.
