Rotorua's Pataka Kai, an open pantry initiative encouraging the sharing of excess kai, is bringing local communities together but some are taking advantage of the generosity.
Organiser Jasmin Wairau said several of the Pataka Kai spots had been temporarily closed because someone was clearing out the groceries.
She said organisers were trying to work out a system to ensure everyone got a fair deal.
"Someone, and we suspect it is probably one person, has been going around all the Pataka Kai and clearing them out. In the weekend I put about 8kg worth of fruit out and within 10 minutes the whole box had been taken. That doesn't benefit the whole community.
"It's disappointing for the others who need to use it. The idea is not to come and do your weekly shop, it's for when you're in those times of need. It should be give and take, if it was working properly there should not be empty shelves - we want to redeliver that message.
