Under the National Government between 2009 and 2017, drilling
rights in the deep ocean surrounding New Zealand were sold off
to big oil companies including Petrobras, Anadarko, Shell,
Statoil and OMV. The Texan oil company Anadarko drilled a deep
sea exploratory well off the coast of Raglan and then another
off the coast of Dunedin risking catastrophic oil spills.
Exploratory drilling is the most dangerous part of oil
production and adding the challenges of drilling in very deep
water compounds the risks. Greenpeace NZ modelled what could
happen in the event of a spill at both sites.
Following a long and hard-fought campaign against deep sea oil
drilling, the Ardern Government put an end to oil exploration in
April 2018 putting NZ's vast EEZ off limits to oil exploration.
