Former Australian Greens leader Bob Brown is to take over running Sea Shepherd's imminent Antarctic anti-whaling campaign.
Watson, 62, who is wanted by Japan under an Interpol "red notice", remains at sea aboard the group's flagship, Steve Irwin.
The Steve Irwin docked at Timaru on Saturday to take on fuel, but Watson switched to another vessel before his ship arrived in port.
He said that 35 years after he founded the group he was resigning from all paid positions, as well as the captaincy of the Steve Irwin, and would remain onboard as an observer of the campaign.
