Tonga are considered to be a tier 2 rugby nation by the International Rugby Board. Tonga has four main rugby playing islands, Vava''u which produced players like Epi Taione, Ha''apai which produced players like Jonah Lomu, Eua which produced the Vunipola family, 8 brothers which all played for the national team and Tongatapu the major island in the Tonga island group. Rugby union is governed by the Tonga Rugby Football Union who are also members of the Pacific Islands Rugby Alliance. Tonga were awarded ''second tier'' status by the International Rugby Board which entitles them to funding from the IRB. The TRFU was founded in 1923, and joined the IRB, in 1987.
