The Vodafone Kaji Rugby Competition is a national primary school rugby competition in Fiji, organised by the Fiji Primary Schools Rugby Union (FPSRU) with the support of Vodafone Fiji and the Fiji Rugby Union. It is currently one of the biggest rugby programs in the nation, primarily targeting grassroots development and promoting young talent.

Since its inauguration in 2002 the Fiji Primary School Rugby Union has grew in intensity and popularity moving past its 10 years of existence and steadily progressing into the future. Kaji rugby has the largest representative of players under the Fiji Rugby Union with 22,000 children participating in the Vodafone Kaji competition in 2019.

The annual Kaji Rugby Festival is the climax of Fiji Primary Schools Rugby Union calendar whereby  representative teams from the provincial regions converge to play in a week long round robin tournament.

The Fiji Primary Schools Rugby Union has also proactively moved the games to different venues over the years so that patrons can feel the festive atmosphere that is experienced during each annual tournament.

Vodafone Kaji Rugby has achieved its mission in developing and exposing the raw talents of our children where some of them are now playing professional rugby around the world today.

In 2018 Vodafone Fiji took the reigns as naming rights partner for Kaji Rugby and as the exclusive mobile telecommunications partner for Fiji Rugby, their consistent support of every Fijian throughout the grassroots of the game, has been invaluable.
