Sheds are disappearing in West Auckland, with two of the structures going missing within days of each other.
St Dominic's School in Blockhouse Bay had their community "sharing" shed stolen over the holidays.
The thieves took the entire shed and its contents, which contained items dropped off to be given to families in need.
Principal Daniel Pepper said the loss of the shed was "a bit sad really".
"It was a great opportunity for the children to see us giving back, I'm sad and disappointed."
