A Rotorua principal has installed filtered water stations for students and is looking at ways to become a "water only school" following nationwide calls to tax sugary drinks.
The calls come after Britain's Treasury chief George Osborne announced a 25p (53c) per litre tax on sugary drinks.
The Ministry of Health released a statement yesterday saying it was encouraging schools to consider adopting healthy drink programmes, supporting a simple schools drinks policy of water and plain, reduced-fat milk.
According to the latest Health Survey results, one in nine Kiwi kids is obese and a further two are overweight.
John Paul College principal Patrick Walsh said the school had built two filtered water stations for students which were proving popular.
