Otago Federated Farmers says the farming community is anxious to see police investigations into rustling resolved to end speculation about the scale of the stock thefts and who might be involved.
Police are investigating reports of a large scale stock rustling ring operating in inland Otago, through the wider Central Otago and Upper Clutha areas.
In the most recent reported cases, more than 150 sheep were stolen in the Cromwell area and 200 pregnant merino ewes from Ribbonwood Station near Omarama last month.
Otago Federated Farmers president Michael Lord says there is a lot of speculation but he is confident that if organised rustling is going on, police will deal with it.
He says if anyone thinks they may have been involved unwittingly they should get in touch with police.
Mr Lord says people could have bought stock cheaply or been asked to kill stock on behalf of someone else.
