The MacRobertson International Trophy (commonly known as the MacRobertson Shield) is competed for by Great Britain, New Zealand, Australia, and the USA. It is held every 3 or 4 years and was last held in the UK in August 2010. The next competition is due in New Zealand in early 2014.
The shield was donated in 1925 by Sir MacPherson Robertson for competition between Australia and England. In 1930 New Zealand were admitted and the competition became a triangular one. The USA were admitted in 1993.
The shield is actually inscribed with 'MacRobertson International Trophy'
