Since its inception in 1968, the Hawaiian Invitational Water Polo Tournament has grown to become one of the largest and most prestigious water polo tournaments in the world. The Hawaiian Invitational also enjoys its standing as the oldest annual international water polo tournament in the world, annually attracting as many as 115 teams from around the world. In the past few years, teams from the Netherlands, New Zealand, Italy, England, Australia, Brazil and Canada have participated in the Hawaiian Invitational.
Tournament participation is open to a wide range of age-group teams: 14 and under, 16 and under, and 18 and under with separate divisions for boys and girls, as well as open divisions for men and women.
Tournament games are held in Olympic-sized, 50-meter pools. The University of Hawaiʻi, Punahou School, `Iolani School and Kamehameha School pools, all located within a twenty-minute drive of Waikiki, serve as frequent tournament sites.
