Blue represents the Pacific Ocean and the peaceful nature of the people. The ring of fifteen white stars stands for the fifteen islands of the Cook Islands group. The Union Jack in the canton reflects the free association with New Zealand and historical ties to the Commonwealth.
History
Adopted on August 4, 1979, when the Cook Islands gained self-government in free association with New Zealand. The design replaced earlier colonial flags while retaining the Union Jack canton familiar to Pacific territories.
