A fishing vessel that spilt diesel into the sea near Stewart Island last week is heading to Lyttleton to undergo repairs to its fuel tank and hull.
The Sureste-700 struck rocks near an area known as The Neck on 26 April, spilling diesel from a ruptured tank.
The vessel has been berthed in Timaru to have the damage assessed and all diesel and water removed from it.
Regional harbourmaster Jim Dilley says it will head to the drydock in Lyttelton for repairs this weekend.
The Canterbury regional council says it will work with the vessel's operators to minimise potential environmental effects.
