Of all the challenges facing Far North oyster farmers, it is thieves who are driving them to distraction.
Mike and Janet Fleming, who own the 4.2-hectare Flamingo Oysters farm at Ota Point, on Whangaroa Harbour, say thefts from their business alone have cost them thousands of dollars over recent years. And thefts were becoming more frequent.
"The farmers are fed up with it," Mr Fleming said.
One raid on their farm had cost them 45 sticks, more than 5000 oysters, while the latest incident, on November 5, was so brazen the thieves continued to load their haul, worth about $300, on to their vehicle even as the Flemings confronted them.
A resident whose property overlooks the bay had called the Flemings to say three people in a small boat were taking oysters from the farm. The Flemings and their son "exchanged words" with the trio, then followed them several kilometres and notified police in Kaeo.
