The wife of an anti-whaling protester says she's had no contact with him since he boarded a Japanese whaling ship four days ago.
Peter Bethune reportedly wanted to present a bill for what he says was the deliberate ramming of his high-speed craft, the Ady Gil, in the Southern Ocean by a ship from the Japanese whaling fleet.
Sharyn Bethune says she's been told her husband is under 24 hour surveillance and has been treated for a cut to his hand.
She says the Ministry of Foreign Affairs says the Japanese whalers intend to take her husband back to Japan, a journey which could take four to six weeks.
Foreign Minister Katsuya Okada said earlier Mr Bethune will be handed over to the Coast Guard when the ship reaches Japan and could face charges.
