The Canterbury Regional Council is responding to an oil spill from a fishing vessel that ran aground on the south coast of Banks Peninsula.
It said all four crew were recovered by helicopter on Sunday night.
The fishing vessel, which was aground at Red Bluff, had about 10,000 litres of diesel and 400 litres of hydraulic oil on board.
The regional council said initial aerial observations showed oil was spilling towards Shell Bay and neighbouring bays, but it could not yet say how much.
