Thieves have been targeting isolated rural properties in the Tararua District, and police are warning farmers to be more vigilant.
Tararua response manager Dave Fraser said there had been a run of burglaries reported in the area, and it appeared the thieves were driving a long way to do so.
"They're targeting quite isolated farms out in the likes of Waitahora and Mangatainoka," he said.
Items stolen include farm equipment and vehicles, and it was unknown whether they were being stolen to order.
It was not the first time police had warned of thefts from rural properties, as there was a spate of burglaries involving equipment and fuel late last year.
