Thieves are using vehicles stolen from Hawke's Bay to carry out night-time break-ins at shops in inland towns.
Cigarettes, alcohol, clothing and machinery are among items stolen and Dannevirke Police Sergeant Tony Lesueur said six burglaries were connected.
"When you put it all together over Manawatu, Tararua and Hawke's Bay it's a fairly significant lot of stealing, and it's concerning because it has been going on for so long and a high value of property has been taken."
He said the first incident was at the Dannevirke Four Square in July.
Then, on September 13, around $14,000 worth of cigarettes was stolen from Dannevirke New World. The stolen vehicle seen in security footage was later found burnt out in Flaxmere.
