The Tasman Rugby Union proudly governs the two sub-unions of Marlborough and Nelson Bays - encompassing 22 clubs.

For players, club rugby is an opportunity to experience rugby at the grassroots level and watch the development of future stars of the game.

The sub unions continue to feild sides at age grade representative level, as well as their senior Seddon Sheild sides - the Marlborough Red Devils and the Nelson Bays Griffins.

The proud histories of both sub unions combine to give their young players a pathway to higher honours via the Tasman Makos.

The annual clash for the Seddon Shield is always hotly contested and after holding the sheild for the past 14 years Nelson Bays let it slip from their grasp to a determined Marlborough Red Devils when they lost to Marlborough 12-13 at Sports Park Motueka on Saturday 28 August 2010.

The 2011 challenge and defence is already being planned by both teams.
