Police are keeping an open mind on the whereabouts of two men wanted in connection with a kidnapping case though inquiries are focusing on the Queenstown region.
They are still looking for Joshua Veint and Pita Wilson after three men were abducted in the Queenstown area last week. A young Queenstown woman is also missing.
Two of the men, Andrew Lee and Casey Johnston, were allegedly abducted on Wednesday, but released soon after.
A third man, Joseph Armstrong, was found by police on Sunday night and needed medical treatment for head injuries.
Inspector Olaf Jensen said police were now also gravely concerned for the safety of Lilly Boden who has been missing since last Tuesday.
