Fuel partner change - effective 1 August 2019
As a valued cardholder I want to let you know about an upcoming change to the AA Smartfuel programme.
Today we have announced that AA Smartfuel has ended its partnership with Caltex, effective 1 August 2019, due to competitive commercial reasons.
But the great news is that by the end of July we will announce our new fuel partners who combined with BP will provide more than 300 sites nationwide.
AA Smartfuel continues to grow strongly with New Zealanders earning a record $132 million in fuel discounts last year.
AA Smartfuel is the only rewards programme that enables New Zealanders to accumulate the biggest fuel discounts simply by shopping with some of NZ’s leading brands, including BP, Countdown, Contact Energy and most recently ASB Credit Cards.
In the meantime you can continue to earn and redeem AA Smartfuel discounts at Caltex up to and including 31 July 2019.
Yours sincerely,
Scott Fitchett
Managing Director
AA Smartfuel Limited
A quick Google search says BP has 210 stations in NZ so my pick for the new provider will be smaller provider like Gull or Allied Petroleum. Don't think it'll be Waitomo as they look like they are going for the least-overhead price as possible (given they are still undercutting Wellington stations significantly).
As for Caltex dropping Smartfuel one can only assume they are bringing in Fly Buys/Airpoints since they are owned by Z Energy or Z Energy will dissolve the Caltex brand into Z
Edit: A quick look at Caltex's Facebook page say they are bringing in the "pumped" discounts that Z have
