Giggles erupted among the stalks on Wednesday as children and adults darted through Whenuakura School's new Maize Maze near Patea.
The maze will be open for business next week, and there will be a community barbecue today for the official opening.
A once-empty paddock next to the school has been transformed with the donated help of local businesses, organisers said.
"The school's got a paddock," board of trustees chairman Joe Crawford said. "There was a big, old, ugly hedge running through it, and we chopped that out, flattened out the paddock."
They decided to put in the maze as a fundraiser for the school. Waverley Harvesting donated time and use of its machinery, while Peko Contracting sprayed the area. Ravensdown provided fertiliser and Farm Source and Pioneer donated seed.
