Experience Good Energy, on the road

Today’s plug-in vehicles are genuine factory models with all the safety and reliability that you’ve come to expect. And because almost 80% of New Zealand’s electricity generation is renewable, your plug-in could help reduce our nation’s reliance on expensive imported fossil fuels. It could save you thousands on fuel.

Help Starship save lives

If your child or a child close to you ever got sick, you'd want to know that they were going to get the best care possible. That's what the wonderful people at Starship dedicate their lives to, and here at Mercury we try to do everything we can to help.

Many hands make light work

Over the years we've helped raise over $5 million for Starship Children's Hospital alongside 30,000 customers who donate on their monthly bill - and we want to make sure that amount keeps growing.

The Level 6 Project

We pledged over $1 million to get the job done and now Level 6 not only offers world-class care to those who need it, it oozes with good energy too.
