Vandals have poured herbicide over a Whangarei bowling green then walked all over the pristine surface.
Each day the damage becomes more evident as the grass dies away to brown patches then black spots on the green canvas. The attack has been described as a "kick in the guts for club members" by Onerahi Bowling Club president Ian Bowick.
"It's upset everyone at the club and this comes after five burglaries at the clubhouse since last December. It's like a personal attack on the club members," Mr Bowick said.
"At least with the burglaries you can fix up a window and that's it. The green is the club's greatest asset and every day we look out and see the damage."
He said the older membership were very upset as the picture of the damage became clearer. Mr Bowick is not sure when the vandals hit the green but a member first noticed something off about the surface on April 8.
