It was most likely to be in the Bay of Islands but could be in the Whangarei area. The two men seen on board as it was leaving Parengarenga lived in Whangarei, he said.
Mr Langford, who owns Rameka Bay Oysters, was away when the $80,000 barge was taken so he moored it close to his Te Hapua home in just a metre of water. He had used it to build his oyster farm but more recently used it as a pleasure boat. The make was Coastal Explorer and it was named Facilitator II.
Mr Langford said he had gone to great lengths to track it down, contacting boating clubs, haulage firms and coastal residents. The Kaitaia aero club had even helped him carry out an aerial search of the coast from Houhora to Whangaroa.
He urged anyone who saw the barge to contact Kaitaia police on (09) 408 6500 with the file number 120823/6816. Anonymous tips can also be passed to Crimestoppers on 0800 555 111.
