It started with free chocolate and ended with people pledging to eat their leftovers.
University of Otago postgraduate food science students Meghan Bennet, Hannah Cox, Felicity Prendergast and Dominic Shepherd held an event at the university to encourage students to reduce their food waste.
They had games, a pledge wall, a smoothie bike and a communal fridge and pantry.
Ms Bennet estimated about 400-500 students took part in the event over the day.
“We are really pleased.
“Our supervisor, who is running the paper, was really stoked.”
There were about 250 pledges on the pledge wall, which included to eat leftovers and buy less food at the supermarket.
The smoothie bike, borrowed from WellSouth, was a highlight.
Miss Bennet said the group offered people free food and talked to them about food and plastic waste.
They were “blown away” to learn the perfectly good food would have otherwise gone to the dump.
The group has to write a report on the event and will be assessed on it.
