Salvage experts are speeding up efforts to pump fuel from a sticken cargo ship - grounded on a reef more than two weeks ago - just off the New Zealand coast.
Improved weather conditions have made the salvage and coastal cleanup easier after a brief stoppage due to a tsunami warning.
(SOUNDBITE) (English) UNKNOWN CLEAN UP TEAM COORDINATOR SAYING:
"There has been a really massive earthquake at the Kermadecs, which is just basically in a straight line that way."
Volunteers returned to work on Saturday, while extra teams were being organized to coordinate greater oil pumping efforts.
SOUNDBITE) (English) MARITIME NEW ZEALAND SALVAGE UNIT MANAGER, BRUCE ANDERSON SAYING:
"One of the things that this team is doing is increasing the amount of power that they have. The more power that they have and pumps they can add into the system, the faster they can get the system going."
There are concerns the weather won't hold, and more severe conditions could cause the Rena to break in two and spill more toxic oil into the ocean.
(SOUNDBITE) (English) UNIDENTIFIED CLEAN-UP VOLUNTEER SAYING:
"It's, you know, quite stressful knowing what could happen and what has happened."
Around 350 tonnes of oil has leaked from the vessel so far and almost 90 containers have been lost overboard.
Some local beaches have reopened, but all have banned swimming.
