The New Zealand Dental Association and Alcohol Healthwatch have both weighed in after a PAK'nSAVE "Good Health Week" promotion included unhealthy foods like fizzy drink, beer, chips and noodles.
Foodstuffs admitted that some of its PAK'nSAVE stores acted inappropriately after images were posted online of signage at the Porirua and Hamilton stores.
A Foodstuffs spokesperson confirmed they were part of a week-long promotion which is now complete, saying "all stores were issued with a template for price signage which has, in these particular instances, not been used appropriately".
Dr Nicki Jackson of Alcohol Healthwatch said discounting alcohol in this way was irresponsible.
"I strongly believe that if PAK'nSAVE Porirua were seriously concerned about the good health of their customers, they wouldn't be selling these alcohol products for $1.15 per standard drink and not having such enormous advertising of these discounted products," Dr Jackson said.
"Especially in low socio-economic areas that are already suffering high levels of alcohol-related harm.
"The day we allowed beer and wine to be sold in our supermarkets, we opened the door to these kinds of mistakes being made - alcohol has become so normalised as a result, as if it is any other product requiring promotion.
Dr Donna Kennedy of the New Zealand Dental Association said the NZDA was "very concerned" to see what had happened.
"There are nearly 40 teaspoons of sugar in a single 1.5 litre bottle of soft drink," Dr Kennedy said.
"One bottle alone contains more than three times the WHO recommended daily limit for sugar for an adult, and more than six times the daily limit for children.
"We strongly suggest PAK'nSAVE reconsider their promotion of sugary drinks as a healthy product."
