Thanks for being part of the Winter Energy Study with Mercury and Kāinga Ora.

We want to give you a heads up that we’re making a change to the Study Terms & Conditions.

Here’s what you need to know: we’re reducing the notice period for changes to the Study and your participation in the Study from 90 to 30 days.

This means that if we’re making changes to the Study, how it works or how you’re taking part in the Study, we’ll let you know about these changes 30 days in advance.

View the full updated terms. These will apply from 07 March 2024.

We hope that you enjoyed the first year of the Study. We're getting all set up for Capped Period 2 in Winter 2024. Stay tuned and you'll hear from us sometime in March about your 2024 cap details.

If you have any questions about your Mercury account, we're here to help. No matter what's going on, we're here to support you. Just call us on 0800 10 18 10.
