Our role in fuelling New Zealand

Crude oil bought by our customers is shipped to our deep-water port at Marsden Point, near Whangarei for refining into high-quality transport fuels. As a toll refiner, we process a range of crude oils imported from offshore markets to produce premium and regular petrol, diesel, aviation and kerosene and fuel oils for our oil company customers.

Most of our fuel production travels via our purpose-built 170-kilometre pipeline to Wiri in South Auckland for storage and distribution by road. The balance is transported by coastal tanker to destinations throughout New Zealand.
