Southland's Graham Low, Brian Hotton and Jan Low have successfully defended their title, this time with Clifford Shirreffs in tow.
Identical to the mixed pairs, five wins and a draw was enough to secure the top spot; their only loss to Kevin Anngow from Timaru-South Canterbury.
North Harbour's Bill Chambers adds a second silver medal to his collection this year. He was runner-up in the National Open Triples in June, and now finds himself runner-up in the National Masters Fours with his team of Ezzy Nezhad, Doug Campbell and Blanche Allport. They weren't too far off the pace either, having won five of their seven games.
Helen Burnley, Kevin Crighton, John Zino and Maree Crighton were the local Hutt Valley hopes and claimed the bronze with three wins and two draws.
