The Territorial Sea Baseline of Cook Islands was derived from two high resolution satellite imageries called Geo-eye and WorldView -2 in 2011 and 2012. These imageries are referenced to the World Geodetic System 1984 (WGS 1984) datum. The baselines were defined and completed by Cook Islands technical team in collaboration with SPC in 2005.

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 exclusive economic zone comprises of 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 territorial sea baseline, every point of which is distant 200 nautical miles from the nearest point of the baseline.
