"Without them we would not have been able to do what we wanted to do. They have made a huge difference to our shop."
Mount Maunganui College head of arts Mike Linklater said painting the mural was made part of the students' end-of-year activities.
"Painting a mural was an activity the students chose," Linklater said.
"It is a win-win. The students' skill levels have improved hugely, this is something they have never done before."
Linklater said the students had painted flowers, teddy bears and other individual characters on the mural.
"There is even a minion thrown in there too."
He said the students had spent three days painting the mural and were expected to be finished soon.
