Save 8c per litre with your Grey Power Membership

Challenge is proud to offer Grey Power members a minimum of 8 cents off per litre on fuel. 

Here's how it works

With My Challenge, in addition to receiving a minimum discount of 8c per litre off fuel (some South Island stores offer up to 12 cent per litre discount), Greypower members will also earn 1 Point for every $1 spent at participating Challenge stores, which can be redeemed 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. The cashier will register you on the spot with your email address. 
  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.
