However, the survey has been dismissed by many principals in Otago and Southland.
Green Party health spokeswoman Sue Kedgley said more than 60% of the 50 schools surveyed were still selling pies, hot dogs and biscuits as a staple part of their school menus, and 64% were selling cakes and slices.
Ms Kedgley said such food undermined children's ability to learn in class and their long-term health. It also undermined the new guidelines, she said.
‘‘There have been some significant improvements, with the sale of pies, hot dogs and chips down by 14%, and 20% fewer schools selling cookies, chocolate and cake. But there is still no fruit on the menu of 40% of the schools surveyed, and 14% do not offer rolls or sandwiches.''
While some schools were clearly improving in response to the school guidelines issued last year, others urgently needed to do more if they were to make the grade by June 1, she said.
‘‘Many parents are facing economic challenges, so price is an important consideration in lunch choices. The best and most costeffective option is for parents and children to make healthy school lunches at home".
Another concern was many canteens were still operating for a profit, and this often came at the expense of children's health.
‘‘It's obviously cheaper to heat up frozen pies than to provide fresh fruit and filled rolls.''
However, Otago Southland Secondary Principals Association chairman Mike Corkery dismissed the survey and said it was nothing but electioneering.
‘‘There are all sorts of circumstances which schools must take into account. We don't need the food police from Wellington to decree what schools can or can't sell in canteens.
‘‘Schools should choose and work through their own policies on what food should be sold. Let them get on with it,'' he said.
