Dr Visser said she was closely monitoring the young whale and had international orca expert Jeff Foster on his way to New Zealand to provide assistance and advice on the best way forward.
Mr Foster has previously led the capture of Springer the orca and returned her back to her pod.
He also worked in Iceland as part of a multimillion-dollar effort to prepare the killer whale Keiko from the 1993 movie Free Willy for release into the wild.
Dr Visser said Mr Foster would be flying in at first light tomorrow and would be out on the water with the orca tomorrow afternoon.
How the orca has become separated from its pod would be pure speculation, Dr Visser said.
