The territorial sea of Tonga comprises those areas of the sea having, as their inner limits, the baseline described in sections 5 and 6 of this Act and, as their outer limits, a line measured seaward from that baseline, every point of which line is distant 12 nautical miles from the nearest point of the baseline.
The 12 nautical mile layer for Vanuatu was extracted from the Global Marine Regions platform (https://www.marineregions.org/) since Vanuatu has not published it officially with UNDOALOS.
Based on the Samoa Maritime Zones Order 2017 which repealed the Maritime Zones Order 2014, the points to be used for
determining the outer limits of the territorial sea are 12 nautical miles from the baseline. The list of the coordinates are stated under the Samoa Maritime Zones Order 2017.
