A new loyalty scheme combining supermarket savings with discounts at the petrol pump will be the largest in the country.
Countdown's loyalty scheme Onecard has combined with AA Smartfuel to bring together their saving schemes on one card.
The combined loyalty scheme will have 3.5 million members and overtake Fly Buys, which has 2.5 million members.
The Onecard AA Smartfuel joint programme will offer members discounts at Countdown, instant savings of 6 cents per litre at BP or Caltex when members spend $40 or more at the pump, and the opportunity to earn supermarket vouchers or accumulate additional discounts at BP or Caltex.
New Onecards will be issued to all active Onecard holders and AA members and all new Onecards, AA membership cards and AA smartfuel cards will be co-branded Onecards,
Countdown's Head of Loyalty Susan D'lima says the new Onecard programme has evolved.
''By partnering with AA Smartfuel we're opening up an instant fuel saving to Onecard holders, and enabling AA Smartfuel cardholders to accumulate fuel savings on what could be their biggest spend per week once the bills are paid.
''Together both programmes give consumers more opportunities to save whenever they swipe, on a single card, and without having to keep track of dockets.''
AA Smartfuel Director, Ian Sutcliffe, said members had been asking for a grocery partnership for some time.
``Countdown is a major addition to the family of participating retailers and it's a significant boost for consumers to be able to accumulate savings on a big weekly spend like supermarket shopping.''
Fly Buys, previously New Zealand's biggest loyalty scheme, will part ways from Air New Zealand's Airpoints scheme on October 17.
Airpoints announced new partners Mitre 10, Tower Insurance and Storage King in September when the split with Fly Buys was revealed.
In June Z Energy announced instant fuel price discounts for Fly Buys members.
