The Auckland Council has approved the issuing of oil exploration permits off the city's west coast in a submission to the Government.
However, it wants the boundaries set 12 nautical miles offshore to protect the endangered Maui's dolphin and the risk from any oil spill.
The Government is looking to allocate petroleum exploration permits in three basins offshore from Auckland at the end of next year.
The basins are the Reinga Northland Basin (85,009sq km), New Caledonia Basin (49,051sq km) and Taranaki (55,032sq km).
The permits allow for exploration at least six nautical miles offshore.
