However, with population increases in the city-based provinces and 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.

Buller (often in combination with West Coast) has had some memorable matches against international sides in the past including a victory over Australia.

In 2014, Buller went through Round Robin undefeated progressing to the Meads Cup Final only to fall to Mid Canterbury.

Rundle was a local business man in the mining industry and former player for the Grey Football Club.

The Rundle Cup is contested annually between the Buller and West Coast teams.
