"It's not just us at Opuawhanga, but [nearby] Otonga has been hit as well, so people from there may want to be part, and even folks from Whananaki."
Ms Dempster said the area was getting great coverage from senior constables Gavin Benney and Russell Rawiri from their nearest police station at Hikurangi.
"But they can't be everywhere all the time. We've got to do something about it ourselves and organise to keep an eye out for each other," she said.
Some locals had got to the stage that they were scared to go out for fear they'd return to find something else stolen.
She said police had told her there had been suspicious cars - one green and the other white - that had been seen regularly cruising the area and people should keep an eye out for them.
