Twenty-one tonnes of oiled debris has been collected from the Tauranga Harbour following last week's oil spill.
An estimated 1500 litres of oil spilled into the harbour when a ship was being refuelled by a Mobil pipeline on Monday.
Bay of Plenty Regional Council on-scene commander Peter Buell said about 95 per cent of the oil had been contained and collected.
He said they would now be focusing on detailed work, such as cleaning oil caught between rocks at the Bridge Marina and rechecking shorelines.
