Adams played at three in his four, alongside lead Peter Raymond, two Colin Field and skip Robbie Robertson.
They beat a very strong Wanganui Bowling Club team 15-7 in the final.
"It was well contested, several ends of very tight bowls," Adams said.
Bates' win was likewise a personal surprise, although Durie Hill were very strong and defeated Aramaho 22-6 in the final.
"I've won plenty of trophies at our club, and then gone down to the centre and never won one, so I think it's my year," Bates said.
Bates has had a lot to be thankful for in 2016 with the occasion of her 80th, getting to hold her first great grandchild, and her son will be getting married later this year. She along with husband Ken are now the oldest members at Durie Hill Bowling Club.
