Occurrence of oil and gas and minerals extraction

  • Image, Oil and gas and minerals extraction.

    The surveying, exploration, production, and decommissioning of offshore oil and gas and minerals can affect marine environments. Extraction processes, ship strikes, collisions with structures, disorientation from lights, and acoustic surveying can affect marine species and habitats. Vessels and structures brought to New Zealand from overseas can also introduce exotic species. Reporting on the location of permits and proposed extractions helps us prepare for potential effects.

    We classified Occurrence of oil and gas and minerals extraction as supporting information.

    Key findings

    Petroleum extraction and associated activities have been carried out in New Zealand since the 1970s. Mineral extraction is at an earlier stage of development.

    • Oil and gas extraction occurs mainly in the Taranaki region.
    • At September 2012, a total of 197 offshore wells had been drilled in New Zealand waters, 176 of them in the Taranaki region (Petroleum Exploration and Production Association New Zealand, nd).
    • In 2014, there were five offshore production fields in the Taranaki region (Ministry of Business, Innovation and Employment, 2014).
    • Although no minerals were being extracted from New Zealand waters in 2015, potential sites were being surveyed and explored.

    Definition and methodology

    Petroleum and mineral extraction includes all stages of the extraction cycle: prospecting, exploration, production, and decommissioning.
