"Walk for Water is a fantastic way for everyone to come together and show that enough is enough and lead the way by showing that although Havelock North has faced adversity, the community is stronger together," he said.
"Those who have been sick are on the road to recovery but our water isn't".
Although there had been a lot of focus on Havelock North, the impact of the crisis is much wider with businesses and homes across Hastings district having to drink chlorinated water.
"Many people have been stuck at home sick or caring for the sick and it's time we came out together in a show of solidarity that shows how important the issue of safe water is to our community," Mr Barber said.
"Many say this is a one-off incident, but we need to make sure that this never happens again and that we can drink from our taps in full confidence that it's clean, unchlorinated water," Mr Harvey said.
The idea to create a community movement came up at a community water forum on Monday, gaining momentum after the Water Crisis public meeting hosted by Hastings District Council, Hawke's Bay District Health Board and Hawke's Bay Regional Council.
The walk is being supported by Ngā Marae o Heretaunga as well as Ngati Kahungunu Iwi.
Organisers hope to get school sport teams involved, because they were significantly impacted with winter sport competitions cancelled during the crisis.
