 Historically Buller were a strong provincial Union particularly in the pre 1960 era and the Union would compete on a level footing with more famous provincial sides such as Canterbury and Wellington.With the formation of the National Provincial Championship (NPC) in 1976 Buller began to struggle as players moved to bigger Unions to further their rugby and work careers.However the Union has experienced a resurgence in fortunes over the last 4 seasons with the representative team performing well in the Heartland Championship.
