CC's and Aztec corn chips have been cut from supermarket shelves in New Zealand and have been replaced by a locally made version of the American brand Doritos.
Bluebird Foods, which makes the chips, is understood to have conducted blind taste tests in which Doritos proved more popular.
The company denies the move is to cut costs. Bluebird Party corn chips have also been discontinued.
All three brands are being removed from shelves and an advertising campaign to announce Doritos has begun.
A long-time customer, who did not wish to be named, expressed anger over the changes.
