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.

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.

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.

A catalogue of over 40,000 gravity survey observations in New Zealand, including free air, Bouguer and isostatic gravity anomalies has been assembled. These data have been assembled from survey measurements mostly made by Geophysics Division, Department of Scientific and Industrial Research, (now GNS Science) since the 1940s using a variety of meters. Some gravity data has been contributed by petroleum explorers and universities. In 2004 all data were uniformly reprocessed using GNS Science software and tied to primary gravity sites the New Zealand Reference Gravity Stations (https://doi.org/10.21420/96Q5-8581). This database is http://dx.doi.org/10.21420/DRDW-VC72.
