Mr Purdie questioned why the Auckland health service was putting the responsibility on shop owners. "Why aren't the teachers the lolly police then?"
While he described the proposal as "pointless", if something like it went ahead in Northland it likely would not impact him much as most of his revenue came from Lotto.
Another store owner, who did not want to be named, said it should be parents not the shopkeepers' responsibility.
Northland medical officer of health Clair Mills said obesity in Northland children was a huge problem.
"Given the challenge of reducing obesity in our community, it is important that conversations and debate on issues like restrictions on the sale of fizzy drinks and lollies is happening," Dr Mills said.
While the DHB did not have a firm position on the recommendations in the Auckland plan, it was interested in looking at any approach to reducing obesity that would be effective and equitable, she said.
"We are facing an epidemic of diabetes and obesity-related ill health in Northland," Dr Mills said. While one in four children were overweight, one in eight were obese.
