Refining NZ is slashing processing rates at Marsden Point to match a sharp drop in fuel demand as the country goes into lockdown from midnight tonight.
The plant, which produces about 75 per cent of the country's petrol, diesel and jet fuel, is halting all non-critical work and will see its daily workforce drop from 600 to about 200 tomorrow. Workers remaining on site will be a mix of staff and contractors focused on operations, emergency services and core maintenance.
The company, 43 per cent-owned by the major oil companies, is working with those customers to determine a revised schedule of crude oil deliveries, allowing for tankers already on the water.
Upgrade work underway on the site's hydrocracker will continue and should be completed in about two weeks. But another work programme scheduled for April and May, including the first inspection and catalyst replacement for the $365 million Te Mahi Hou petrol making unit commissioned in 2015, will be deferred.
Managing director Paul Zealand said the refinery's processing facilities will be operated on a rotating basis to continue fuel production at substantially lower rates. Safety-critical work will continue but all other work will be suspended.
