Save 8 cents per litre with your Grey Power Membership

Challenge is proud to serve Grey Power members – and proud to be your 100 percent “Kiwi-As” service station. Your Grey Power membership card now enables you to get a minimum of 8 cents off on fuel with Challenge! 


Important changes effective 1st December 2019

From 1st December 2019, Grey Power Members will need to be signed up to My Challenge in order to receive the full discount (between 8 cents and 15 cents per litre depending on the store you visit).  For those that are not signed up to My Challenge, the fuel discount you qualify for will be reduced to 6 cents per litre.

Then from 1st April 2020, Grey Power members will only qualify for a fuel discount if they are signed up to My Challenge.


Here's how it works

With My Challenge, in addition to receiving a minimum discount of 8 cents per litre on fuel (some South Island stores offer up to 15 cent per litre discount), Greypower members will also earn 1 point for every $1 you spend, which you can redeem for rewards in store.

My Challenge is also unique, as you can choose to support local causes in your community by donating your fuel discount or My Challenge reward points to the community groups your local Challenge has chosen to support. Signing up is simple:

  1. The next time you’re at a participating Challenge station, tell the staff at the counter that you’d like to sign up to My Challenge, and show them your Grey Power Membership Card;
  2. They can register you on the spot with your email address and it only takes a minute. 
  3. You’ll be given an exclusive Grey Power version of the My Challenge card (which is scanned instead of presenting your Grey Power Membership Card) and can start benefiting right away.
