The Maritime Zones Act (MZA) 2018 for Cooks Islands repeals the Territorial Sea and Exclusive Economic Zone Act 1977, (Act No. 16 of 14 November 1977). It states that the territorial sea comprises of those areas of the sea;
(a) having as their inner limits the breadth of the territorial baselines and is measured from the low-water mark along the coast of the Cook Islands or where there is coral reef along any part of the coast of the Cook Islands, the low-water mark along the outer edge of the coral reef.
The Provision of the Interpretation Act 1971 defines the “Nauruan territorial waters" as:
That area of water, and the waters and subsoil beneath it, enclosed by a line every part of which is at a distance
of twelve miles from the nearest point of the outer edge of the reef surrounding the Island of Nauru which is exposed at low tide and, where there is an opening in the reef, from a straight line across the outer edge of that opening.
The Marine Zones (Declaration) Act 2011 repeals the Marine Zones (Declaration) Act 1983. It states that the territorial sea of Kiribati comprises those waters having, as their inner limits, the baseline of Kiribati and, as their outer limits, a line measured seaward from that baseline, every point of which is at a distance of twelve (12) nautical miles from the nearest point of the baseline.
