A resource has been developed to help community groups run water-only events.
In the six months since the first water-only event took place - the Paetamariki Primary Schools Kapa Haka competition run by Upokongaro School in September 2016 - the Whanganui, Rangitikei and Ruapehu districts have seen increasing numbers of event planners opting for water only.
Whanganui District Health Board's nutrition and physical activity health promoter Karney Herewini is applauding the response.
"The work that's been undertaken with water-only schools has highlighted an opportunity for the water-only initiative to extend outside of the school gates," Mr Herewini said.
"It's great to see our community being proactive about making the healthier choice easier for everyone."
