Last month at Whanganui High School, the call went out for cans of food and non-perishable goods for City Mission Foodbank.
It was a school house competition but also an effort to help those in need.
By the end of the can drive on Friday, the students had amassed 3789 cans and grocery items, enough to fill an office. On Monday, the collection was delivered by trailer to its destination.
"Last year [the school] gave 600 cans in total," says Myles Simpson, one of the school prefects and co-head of community. "We made sure it was a house competition."
After that, he says, it was all about promotion, using every digital and analogue facility available to get the word out and encourage students to bring in cans for the cause.
