Consumers have vented their frustration at the lack of chips in some bags of Bluebird's Mega Value Snack Packs - with some even finding bags without any chips in them.
The packs, which contains 22 packets of chips from their Ready Salted, Grain Waves and Twisties range, is a common filling for lunchboxes around the country.
Some have taken to Bluebird's Facebook page to complain.
"I open up a pack of Grainwave chips and there is just 6 tiny chips in there," one person said.
"Just doing kids lunches and opened brand new 22 snack pack and found a whole pack of chips empty! My mega value not so value now."
Bluebird responded to some posts on Facebook explaining that chips are sold on weight not volume and are filled to the weight printed on the outside of the packet.
But complaints haven't been limited to just the small packs of chips.
"So I decided to buy some Poppa Jacks and they were 1/4 full.. What do you call that??" another person said.
"Not a happy customer."
Consumer NZ say those who are left without any product should seek a refund.
"Consumers who've purchased the product and found no chips in one of the bag are entitled to a refund," they say.
"The same would apply if the bags were significantly underweight."
Bluebird has been contacted for comment.
Another woman took to Facebook to explain she isn't happy with the lack of crisps in her packet.
"[I] just opened a bag of chips and there is only like a 3rd of what there should be in it. For someone who is highly addicted to your salt & vinegar thin cut chips I'm not happy."
