This page contains data tables for oil production, transformation and consumption. It also includes some brief outlines of distribution and storage of oil products in New Zealand.
Data tables for oil
This spreadsheet contains the latest data on oil production, imports, exports, stock change, refining, and consumption in New Zealand. The tables are updated quarterly.
Revisions to previously published data: The Ministry has improved the methodology for producing oil production and consumption statistics, as well as updating some historical data. This has resulted in changes to previously-published data. These are detailed further in the Oil data tables.
Monthly oil supply statistics
The Ministry has released an experimental monthly data series containing supply-side data (excluding consumption), which can be found below. Consumption data is contained in the quarterly data series above. A decision will be made in June 2021 on whether to make the monthly series permanent.
The next publications of the monthly series can be expected on:
- 13 May 2021
- 10 June 2021
Oil reserve statistics
Oil, gas and LPG reserves statistics are available in the data tables on the Energy in New Zealand page.
Oil is New Zealand’s largest source of energy and therefore has a strong influence on our economy. Deregulation of the oil industry in 1988 removed price controls, government involvement in the refinery, licensing of wholesalers and retailers, and restrictions on imports of refined products. New Zealand exports local crude and imports both crude and refined petroleum products.
Domestic oil production
Oil is extracted from several fields in the Taranaki region. Nowadays, the Maari and Pohokura fields make up over half of domestic oil production. Maui, discovered in 1969 and beginning production in 1979, formerly provided the majority of domestic oil, but has since declined in significance.
Detailed information on current and historical petroleum permits can be found on the New Zealand Petroleum & Minerals website. This site also contains industry overviews, free technical data, maps and latest news from the industry.
While there are several producing oil fields in New Zealand, we are a net importer of oil. New Zealand’s locally-produced oil is generally exported because of its high quality and therefore high value on the international market. Australia buys most of this oil.
The Middle East tends to be our largest source of crude oil — over half generally comes from there. Russia and Asia are also significant trade sources.
A small minority of the domestic consumption of petroleum products comes through imports from foreign refineries, predominantly located in Singapore and South Korea. There are around 15-20 tanker movements per month importing crude oil, feedstocks and petroleum products to New Zealand.
The Marsden Point Oil Refinery, near Whangarei, is New Zealand’s only oil refinery. It's operated by Refining NZ. The refinery began operating in 1964, and is capable of processing enough oil to meet a majority of domestic demand.
Refining NZ processes crude oil and condensate for the 3 biggest oil companies active in New Zealand — BP, Mobil and Z Energy. Each of these companies has a stake in the refinery, with other shareholders holding a minority.
The refinery produces a full range of petroleum products: petrol — diesel, kerosene-type jet-A1, fuel oil, bitumen and other petroleum products — but not aviation gasoline or lubricants.
Sulphur is recovered as a by-product and sold as a feedstock to the fertiliser industry. Recovered carbon dioxide is sold to the beverage industry.

Oil: An Introduction for New Zealanders
This publication is designed to provide an easy-to-read background briefing for anyone who will be dealing with oil-related policy issues. These include elected officials, business leaders, non-governmental organisation leaders, researchers, students, and concerned citizens. The book does not attempt to analyse any policy issues, but rather to provide basic information that will be useful to anyone who does.
Topics covered include:
- oil production and refining technology
- the uncertainties surrounding statistics on world oil reserves and resources
- the management of New Zealand's own oil resources
- the structure and regulation of New Zealand's oil industry
- New Zealand's involvement with international efforts to promote oil security.

Consumption of petroleum products
Diesel and petrol continue to dominate petroleum product consumption in New Zealand. Diesel is the primary fuel used for commercial land transport, therefore its use is strongly linked to economic performance. Petrol consumption tends to be for private use.
New Zealand’s oil consumption statistics are primarily collected via the Delivery of Petroleum Fuel by Industry (DPFI) survey. This is a survey of fuel deliveries to economic sectors (including independent distributors) by the 4 large oil companies operating in New Zealand — BP, Mobil, Z Energy and Gull.
Independent distributors are also surveyed to allocate to economic sectors. Fuel deliveries made by independent distributors between 1990 and 2006 were estimated, as no information was available for these years.
The report Delivering the Diesel – Liquid Fuel Deliveries in New Zealand 1990 – 2008 outlines the methodology employed to perform this calculation.
Distribution and storage of petroleum products
The 3 largest domestic oil companies own bulk storage facilities throughout New Zealand and have agreements in place that allow access to each others' storage facilities. This enables them to draw stock from any location — if they have authorisation and sufficient stock in another location. This pooled storage system allows the companies to jointly manage stock levels and co-ordinate import shipments of petroleum products.
Gull operates its own independent petroleum storage terminal at Mount Maunganui. Products are transported from Mount Maunganui to Gull’s retail outlets by road tanker.
The petroleum delivery infrastructure in New Zealand incorporates:
- import vessels
- domestic coastal tankers
- port storage facilities for bulk shipments
- a 170km pipeline from the refinery to the Wiri depot near Auckland International Airport, and a Jet Fuel pipeline from the Wiri depot to the airport
- road tankers
- independent distributors who both:
- deliver petroleum products on behalf of the wholesalers
- purchase their own fuel at wholesale prices to deliver to their own customers.
