The term Territorial Sea Baseline refers to the line from which the seaward limits of New Zealand's maritime zones are measured. The breadth of the territorial sea, the seaward limits of the contiguous zone, the exclusive economic zone and, in some cases, the continental shelf, are measured from the Territorial Sea Baseline.

Basin Extent Data Sources Polygon Layer. The polygons show the provenance of information used to compile the sedimentary basins extent data layer. The 35 scientific papers and consultancy reports used are in the public domain. The quality of information used is variable, ranging from GNS Science consultancy reports based on modern high quality seismic surveys, to regional interpretations based mainly on gravity data. Clicking on an individual polygon will bring up a link to the data source. This is a reconnaissance-level map only.

New Zealand Exclusive Economic Zone (EEZ) is the area of sea and seabed that extends from 12 to 200 nautical miles offshore. It is the fifth largest EEZ (approximately 430 million hectares) in the world, about 15 times the size of our land mass. United Nations Convention on the Law of the Sea.
