Central Kids Rewi Street kindergarten had four plant boxes filled with growing vegetables, but on Tuesday, October 18, nine broccoli and cauliflower disappeared.
The previous Sunday a stake was taken from the kindergarten's growing lemon tree.
Some of the vegetables were found on the road by staff the next morning and the tree stake is yet to be returned.
The community garden was established on the footpath outside Central Kids Rewi St kindergarten in June this year to share fresh produce with those in need.
"We've got the theory that if someone needs the vegetables, they take it," Central Kids Rewi Street teacher Michelle Anthony says.
