More than 2000 tonnes of liquid and solid waste has been disposed of from the Rena disaster so far, Maritime New Zealand says.
Good weather has been aiding salvage efforts this week, although swells are forecast to increase later in the week, with a change in the weather to northeasterly winds.
Twenty containers were removed from the stricken vessel, which has been grounded on the Astrolabe Reef off Tauranga since October 5, bring the total number of containers removed to 165.
Maritime New Zealand said there has been no change to the state of the vessel overnight, and while a light sheen of oil extends from the vessel, no black oil is visible.
So far, 960 tonnes of waste has been disposed of from shoreline cleanup operations.
