A number of schools in the Whanganui region promote good health by encouraging children to drink only water.
And health promotion officer Karney Herewini is welcoming a move by some boards of trustees to enshrine the practice in their school policies.
In his role as nutrition and physical activity health promotion officer for the Whanganui District Health Board, Mr Herewini has been visiting schools in the region to promote the water only message.
Mr Herewini says he wishes to congratulate the Upokongaro School board which has given principal Warren Brown the mandate for the school to officially become water only.
"While the school's 91 year 1 to year 8 students and staff had been practising water only for the last 18 months it means a great deal to us to be able to officially call ourselves water only," said Mr Brown.
