A new company has been set up to carry out much of the contracting work at Marsden Pt Oil Refinery after Refining NZ changed the way it uses contractors at the country's only oil refinery.
The change sees four firms - McKay Electrical, Culham Engineering, Industrial Site Services and United Civil Construction - set up a new company, Maintenir Ltd, to take on the contracting work.
Refining NZ chief executive Sjoerd Post said the changes will save the company money and increase profits for shareholders, many of whom live in Northland.
However, Mr Post said, there was no guarantee the savings would be passed on at the pumps as that was a decision for the companies the refinery sold its fuel to.
He said the announcement of the changes was made to the 14 companies that contract work at the refinery last week, after the refinery reviewed its contracting process.
