It follows a bunch of rubber mats stolen from outside the courts at the beginning of the season.
"We had them at the main entrance of the courts, to stop the gravel coming in. I don't know what people are doing.
"I think the mats were stolen for a purpose, but the parking signs, I guess people are just being funny. What are they going to do with them, put them on their front lawn?"
In 2019, Rotorua Netball had to fork out an extra $500 before the season started after the "disappointing" theft of one of its brand new goal post from the Westbrook courts.
A mere five months later, three "keep off the grass" signs were also allegedly stolen.
STOLEN: Our "Keep off the grass" signs - three of them! So maybe you had a party and you didn't want people parking on...

Thompson said aside from the rubbish bins, there wasn't much more that could be stolen.
"You can return all the items without question to the gates."
