Rural property owners need to make sure all buildings and vehicles are locked and secure, police say.
The warning follows reports of suspicious people spotted in the Renwick and Rapaura Rd areas.
Constable Andrew Holdaway, of Blenheim, said police had been getting more reports of suspicious people and vehicles seen on properties in rural areas, with about seven cases reported during the past two weeks.
He urged people to report all suspicious behaviour immediately.]
