The oil and gas industry in New Zealand explores and develops oil and gas fields, and produces and distributes petroleum products and natural gas. In 2018, New Zealand's self-sufficiency in oil (mmbls production divided by consumption) was 17%, i.e. the country imports its petroleum product needs. All local oil production is exported as the New Zealand refinery is not suited to processing it. In 2018, 60

The low-pressure gas pipelines that distribute gas to end users are owned by First Gas (Northland, Waikato, Bay of Plenty, Gisborne, Kapiti Coast), Vector (Auckland), Powerco (Hawke's Bay, Taranaki, Manawatu, Wellington) and GasNet (Wanganui). The largest retailers of gas are Contact Energy and Vector. There is no natural gas transmission in the South Island. New Zealand has one underground gas storage facility, the Ahuroa Gas Storage Facility.

, including producing wells and refineries. The last refinery there was closed in 1972. The field continues to produce small quantities of oil. The

gas field in South Taranaki was discovered in 1959 and brought into production in 1970. The North Island natural gas network started operating in 1970, initially supplying Kapuni gas to Auckland, Hamilton, New Plymouth, Wanganui, Palmerston North and Wellington. The off-shore

field was discovered in 1969 and brought into production in 1978. This supported the development of many large energy projects, including gas fired power stations at

and Huntly, ammonia-urea plant at Kapuni, gas to methanol plant at Waitara and the synthetic petrol plant at Motunui. In 2018, the government announced that no new permits would be issued for offshore oil exploration. In 2021, the last of the deep sea oil and gas exploration permits outside Taranaki was surrendered. This was the Totara permit held by NZOG for an area in the Great South Basin of the south coast of the South Island.
