Help your dearest go further

No matter where you live in Aotearoa, you can share your virtual litres with up to 5 of your friends, family or use them yourself. For whatever reason or need that arises, Sharetank is the perfect solution by having pre-purchased fuel at your best local Z price.

Share with up to five people

You have the option of sharing your virtual litres with your teenage kids, giving you peace of mind they won’t be stranded, or perhaps your grandma only uses her car twice a month and you want to make sure she’s fuelled up and ready to go. Whoever you share with and whatever your situation, we've got your back. Of course, you also still have the option to keep your entire Sharetank to yourself.

Share everywhere, use anywhere

Have your kids flown the coop? Perhaps you’re living in Tauranga but they’re in Timaru. Or you can add pre-paid litres in Cambridge and then fill up yourself in Christchurch. How you use your litres at Z is up to you!

Managing your account

Z App has a simple and clear dashboard for you to keep track of your account in real time. You can check your rewards, fuel balance, savings and keep track of your spend. You can also manage who has access to your tank at any one time and see what they've used.

Every transaction secure

Your payment details are kept securely in the Z App. Every litre you purchase is handled within the app.

We all need a little extra sometimes, and on our bonus litres days you are rewarded with free litres when you pre-buy 150L or more.
