"We've had several incidents in the last two or three years and just yesterday we found that somebody had physically dug out and taken some roses," Cath Matthews said.
"This is the fourth or fifth time somebody has abused the privilege of us having that little garden there for everybody to enjoy and we're a bit annoyed, obviously."
It is the latest in a string of robberies from the garden, situated North of Kaitoke on State Highway 3, and which includes the taking of picnic chairs, the picnic table and cut flowers.
"I've had people pinching cut flowers, I actually got the police on to them and they found out who they were. We're kind of at that point now where we're wondering 'why do we bother?'
