Thieves are targeting vehicles under the cover of night in some areas of Napier.
Detective Sergeant Glenn Restieaux from the Hawke's Bay Police Tactical Crime Unit said Napier Hill and Napier South were areas "of highly reported thefts".
"In the last two weeks of May up to June 3 there were 40 thefts from vehicles reported in Napier," he said.
"About a quarter of reported thefts are from unsecured vehicles. Offenders are smashing windows and using instruments to open the door".
Georges Dr, Nelson Cres and Vigor Brown St were just some of the roads being blitzed.
