AUCKLAND, June 14 - To mark Men's Health Week, which runs through to Sunday, Kelston Boys' High School has had a "walk for water", raising funds for a new water fountain and for water bottles.

Last year, the Health and Education ministries made an announcement to encourage schools to provide students with water and milk only.

The NZ Dental Association and Auckland-based Hapai Te Hauora say Education Minister Nikki Kaye should make water-only a requirement at all New Zealand schools.

Hapai Te Hauora chief executive Lance Norman says his organisation has long been against sugary drinks in schools.

"Given their high Maori and Pacific roll, we're especially pleased to see a school like Kelston Boys' leading the way," he said.

"We hope the minister takes note and demonstrates leadership in supporting water-only schools."

Since last June, NZDA dentists have backed schools having just water available.

"Kelston Boys' is a great example here," NZDA spokesperson Dr Rob Beaglehole said. "But the minister could step up and have an impact on the health of all students."
