Part 2 of the Tuvalu Maritime Zones Act 2012 states that the contiguous zone comprises those areas of the sea that are beyond and adjacent to the territorial sea, having as their outer limits a line measured seaward from the baseline every point of which is distant 24 nautical miles from the nearest point of that baseline.
Where an archipelagic baseline is declared, the outer limits of the contiguous zone are a line measured seaward from that archipelagic baseline, every point of which is distant 24 nautical miles from the nearest point of that archipelagic baseline.
Part 1 of the Tuvalu Maritime Zones Act 2012 states that the territorial sea comprises those areas of the sea having
(a) as their inner limits, the baseline, which is measured from the low-water line of the seaward side of the reef fringing the coast of any part of Tuvalu or bounding any lagoon waters adjacent to any part of that coast, or where a reef is not present, the low-water line of the coast itself and
(b) as their outer limits, a line measured seaward from that baseline, every point of which is distant 12 nautical miles from the nearest point of that baseline.
The Tuvalu Contiguous Zone was measured from the following; i) the low water line of the seaward side of the normal baseline (coast), the low-water line of the seaward side of the reef fringing the coast and bounding any lagoon waters adjacent to any part of that coast. (ii) The archipelagic baseline measured seaward with a distance of 200 nautical mile (370.4 km; 230.2 mi) from the nearest point of that archipelagic baseline.
Part 4 of the Tuvalu Maritime Zones Act 2012 states that the exclusive economic zone of Tuvalu comprises those areas of the sea, seabed and subsoil that are beyond and adjacent to the territorial sea, having as their outer limits a line measured seaward from the baseline; which is measured from the low-water line of the seaward side of the reef fringing the coast of any part of Tuvalu or bounding any lagoon waters adjacent to any part of that coast, or where a reef is not present, the low-water line of the coast itself every point of which is not more than 200 nautical miles from the neares
