Burglars targeting cigarettes and tobacco in Hawke's Bay may be supplying an underground black market, police say.
Since late July, local dairies, Four Square stores, service stations and discount tobacco specialists have been targeted by accomplished thieves, taking all they can get their hands on.
They were striking regularly and acting fast, often getting in and out within a matter of minutes.
"We are getting approximately two to three burglaries targeting commercial premises every week to 10 days," Detective Sergeant Craig Vining said. "Cigarettes and tobacco are the primary target, cash and other items may be targeted if they are on hand at the time."
The rate of offending was increasing, with two Four Square stores and a discount shop in Hastings hit overnight on Wednesday last week.
