Originally, countries around the Pacific Rim held fledgling Masters tournaments, but as European nations embraced the concept, it was realised that a global organisation was needed.
In 2008 the IMHA was formally recognised by the Federation International de Hockey (FIH) as the official body for Masters Hockey in the 35 – 60 age groups.
The main aim of the IMHA is to promote and develop international tournaments for Masters Hockey players of all hockey nations, not only for elite players selected for their country, but also for those who want to compete against Masters players of a similar standard from other countries.
From a starting point of a few teams from the original five Pacific Rim countries, the number of teams competing in IMHA tournaments has grown to over 70.
When IMHA tournaments take place close to venues for major events on the FIH Calendar, IMHA players can play in their own competitions and then watch world class hockey.
In 2014 the IMHA became a limited company registered in Scotland in the UK.
