A "big success" last year for the 'plan before your party' summer campaign with the local police will be coming back.
"Kids had so much fun throwing sponges."
Children will also have a range of new entertainment available. Food will also be available in the premises.
And there's much more to see, Kelly said.
"I want to showcase locals and want this fair to be a reflection of our community. I would love people to come and see children getting creative, quality food and stalls and our big push on sustainability," she said.
Last year, Kelly said the event attracted a "huge amount of visitors".
"I was totally not expecting this so this year there is some pressure to maintain the level of enjoyment," she said.
Last year, the team recorded more than 600 people visiting during the first 10 minutes of the opening.
More information: The Summer Fair is tomorrow 10am to 4pm. Wilson Park, Citrus Ave, Waihi Beach. Open to all ages. Entry: $2/person and free for under 12.
