"It has been incredible," Merenia said.
"In the first three days of this campaign we filled three boxes, and calculated each box had 40 to 45 cans in each."
She thought the massive increase of cans might have been because a rock painting craze that many people were involved with.
People have been painting rocks and leaving them in various public places for others to find.
Two representatives from the Salvation Army, Lieutenants' Sarah and Andrew Green, collected the boxes of cans on Thursday and took them to the foodbank which is based in Magrath Ave, Paraparaumu Beach.
