  • Refining NZ operates 24 hours a day, seven days a week, 365 days a year processing a wide range of crude oil types to produce premium and regular petrol, diesel, jet fuel, fuel oil, roading bitumen and sulphur.
  • The refinery was significantly upgraded and expanded in the 1980s. Further investment since 2005 has lifted capacity and capability further with around $735m invested in expansion projects, including the $365m Te Mahi Hou project which replaced a 1960s semi-regeneration platformer with a CCR (Continous Catalytic Reforming platformer).
  • The refinery has a crude oil capacity of 135,000 barrels a day.
  • The refinery produces around 58% of New Zealand petrol demand, around 85% of New Zealand Jet fuel demand and around 67% of New Zealand’s diesel demand.


  • The crude oils and feedstocks that are refined into transport fuels at Marsden Point are owned by our oil company customers. Crude is delivered from around the world to the Marsden Point jetty predominately from the Middle East and South East Asia.
  • Petrol, Diesel and Jet fuel destined for Auckland and the Waikato is pumped through the RAP (Refinery to Auckland Pipeline) to a terminal at Wiri. The throughput is typically around 320,000 litres per hour, enough to fill the tanks of 8,000 cars every hour.
  • Petrol and diesel for Northland is delivered by road from a truck loading facility opposite the refinery. Petrol, diesel, jet fuel, fuel oil and bitumen for the rest of New Zealand is transported via coastal tankers. Naphtha for petrol production and some fuel oil are exported. Sulphur and some bitumen is delivered by road.


  • As a toll refiner we have two main income streams – processing fee income and pipeline fee income. Further fees are paid by customers for refining their crude oil and other feedstock into final products. Fees are paid by customers for pumping refined products via Refining NZ’s pipeline to Auckland.


  • Refining NZ employs around 400 staff and has an extended team of around 250 local contractors. Contractor numbers are flexible and are dependent on the level of maintenance and repair required at any time.
