Customers of a Christmas saving scheme are upset they can't spend their money at a supermarket as they had hoped to.
Hampsta, which started in 2008, has cut Countdown as a participating retailer.
Countdown says it was Hampsta that made the decision to remove it as the scheme's sole grocery outlet.
Customers say Hampsta isn't giving them information.
Consumer New Zealand chief executive Sue Chetwin says the company needs to be more up front.
"They should do that and they should perhaps let their customers know if they are in any negotiations with a supermarket given that probably quite a lot of their customers have actually joined them. You know, they do want to be able to buy groceries for Christmas."
Ms Chetwin says Hampsta's terms and conditions mean its customers could only take their saved money out before the start of September.
Hampsta says it's working on a replacement offer but isn't saying anything else.
