A Northland farming representative is encouraging those whose stock has been stolen to report it on a new website so the industry can identify hot spots.
The call comes after 86 sheep were stolen from Far North Te Paki Station and another 24 were taken from a neighbouring farm late last month.
Federated Farmers Northland Provincial president, Roger Ludbrook, said farmers needed to support "Stop Stock Theft", this country's first ever online map designed to report and track suspected stock theft.
Stock rustling reportedly costs the country $120 million a year.
Mr Ludbrook said beef and sheep farmers were already struggling with the high NZ dollar and difficult market conditions meant stock theft was just another blow to rob them of vital income.
