The Labour Party will make food manufacturers reduce the sugar content of processed food and use prominent labels listing how many teaspoons of sugar and salt was in a product.
Labour's health minister Annette King set out the anti-obesity policy at the party's annual conference in Palmerston North today.
She said the Government's recent obesity package was a "feeble attempt" at addressing the problem.
If Labour was in Government, it would give a time frame for industry to reduce sugar content in all processed food.
It would also require labelling on the front of a package - as happened with tobacco - that was easy for people to understand.
