A resident in the area, Kevin Middleton, whose property borders the gully, was disgusted by the vandalism. "They (the students) had aesthetically made the area a lot brighter. When this sort of hooliganism occurs we all pay the price."
He's right, of course.
And that's what is so disturbing about acts of vandalism.
The perpetrators aim to destroy or undermine efforts to improve the world around them.
Unable, or unwilling, to contribute they seek to tear something down.
Otumoetai College principal Dave Randell is calling for anyone with information on the attacks to come forward.
"It's not just the financial cost, but all the time and effort that has gone into these projects only to have some idiots come along and ruin it."
It's important to note that the vandals have not won.
If anything, such attacks can draw communities closer together.
Mr Middleton took it upon himself to clean up the area and replant some of the trees after he saw what the vandals had done.
Hopefully, in the near future, the students will be able to help replant the area to show those responsible how pointless and insignificant their actions were.
