Thirty-one per cent of New Zealand adults are obese - the third highest rate in the developed world - and 11 per cent of children.
Local dentists also say it sends a strong message about the impact sugary drinks have on children's teeth.
Lead dentist at Lumino The Willows, Paul Blears, says the move is a step in the right direction.
His practice sometimes deals with children coming in with 10 to 12 cavities each "and it's all down to the stuff they are drinking".
Of course, this move alone will not solve the country's obesity problem.
It's a good first step and ensures that health authorities are making a stand on the issue.
A Ministry of Health adviser says it is important health boards have a leadership role in these healthy food policies. They have certainly achieved that.
Hopefully, the stance taken by the Ministry of Health will add more fuel to the debate over healthy eating.
In a perfect world, every individual would take charge of their diet and get regular exercise.
However, if one-third of adults in this country are obese then that points to a wider systemic problem.
