Fuel thefts from a North Otago farm last week highlight the need for farmers to be security-conscious.
Federated Farmers rural security spokesman Miles Anderson said it was a constant battle to protect farming properties.
He was responding to news that both a 1000-litre and a 400-litre petrol tank were emptied on an Enfield farm, west of Oamaru.
Farmers needed to be careful where they installed items like fuel tanks, Mr Anderson said.
