The hazardous operation to remove toxic fuel from stricken container ship Rena resumes.
Calm weather now is allowing salvage teams to park a fuel tanker barge close to the ship - grounded off the New Zealand coast.
Officials say they have a window of five days to remove the remaining 1200 tonnes of oil.
But the desperate race to pump the fuel has been hindered by technical problems, bad weather and a heavily listing vessel.

"We've got complexity, heaped on top of complexity, heaped on top of complexity. So, it's not a simple job."
Nearby beaches may look back to normal but authorities have discovered that many beaches have a layer of oil hidden just beneath the surface.
Around 350 tonnes of oil from Rena has already spilled into the sea.
