Until 2014 the primary telecoms provider for the Cook Islands was a joint venture between the government and the former Telecom New Zealand (now Spark). In 2015 Telecom Cook Islands was sold to the BlueSky Group, who also operated networks in American Samoa and Samoa. In 2016 BlueSky was acquired by Fiji's ATH group.

The Cook Islands's primary connectivity is through the O3b medium earth orbit satellite network, with connections to Rarotonga and Aitutaki. C-band geostationary satellite links connect smaller islands together. Rarotonga and Aitutaki have developed market infrastructure including fibre, DSL, and 4G mobile networks.

BlueSky Cook Islands will be connected via fibre to the global Internet in 2019 through a new cable called Manatua.
