The deal reconnects Trust House with the Wairarapa-Bush Heartland team which it last sponsored in 2008 and builds on its earlier support for Trust House Memorial Park.
Mr Hargood said the Heartland competition provided a pathway for provincial players to progress further into professional rugby.
"It's a chance for our players to perform on the national scene and for the Wairarapa community to enjoy twelve teams from around New Zealand playing on their doorstep."
Trust House Wairarapa-Bush will wear their new strip when the 2013 Heartland competition kicks off on August 24.
Their first game is against North Otago in Oamaru. Four home games will be played in Masterton before the semifinals in mid-October.
