The incidents have happened on Sunday nights on Highsted, Veitches and Cavendish Rds in Bishopdale and Casebrook.
Highsted Rd resident Christina Davey was watching TV when a rock was thrown through her window about 10pm.
“I was sitting on the couch watching TV and it happened right behind me,” she said.
Miss Davey called 111, and was told by police it was wilful property damage. They did not investigate it further.
“I don’t sit in front of that window anymore, I’m just so pleased my son was in bed asleep,” she said.
Christchurch North Community Patrol chairman Sam Hall said the patrol had noticed an increase in thefts and burglaries in Bishopdale.
“It has been pretty bad lately, but give it a month and they’ll be somewhere else,” he said of problems across the north-west suburbs.
In August, the patrol reported 52 suspicious vehicles, 10 incidents of suspicious behaviour, found five stolen cars, performed multiple welfare checks and reported 108 pieces of graffiti throughout suburbs across the north west.
But police say they are not aware of anything out of the ordinary in regards to crime in the area.
Senior Sergeant Roy Appley said he was not aware of any specific issues in Bishopdale until the Nor’west News spoke to him about the incidents of rocks through windows.
“Rocks through windows is not a normal occurrence, but residents should know there is a sergeant and five constables specifically focused on Bishopdale and the north west,” she said.
He said communication was “working well” between the community patrol and police.
