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 petajoules of crude were produced in New Zealand, 380 PJ of petroleum products imported (most of it crude), and 283 PJ consumed. The difference is exported or used for international travel (aviation fuel and similar).
