Cadogan (70), a retired coolstore manager, teamed with Marilyn Holmes to win the Otago champion of champions pairs. It was the fifth title and gold star for Holmes.
They beat the Green Island pair of Nick Sinclair and international Daniel French 10-8 in the final at the Dunedin Indoor Bowls Centre.
The Momona pair gained a significant break midway through the game when a French weighted shot pushed the jack off the mat and Cadogan and Holmes were given three bonus points.
Momona held on to the three-point cushion until the second-last end when Cadogan accidentally killed the end and lost two points to lead 9-8 before the final end. They gained a point on the last end.
``I didn't think I'd ever get there,'' Cadogan said.
``It's been one of my goals for a long time. It was pretty special to beat Daniel.''
He won his 19th title two years ago.
Holmes started indoor bowls in 1996 and won her first title in the open fours in 2004 and her fourth in the champion of champions fours three years ago.
``It was a relief to get my fifth title.'' she said.
``I have been runner-up to Daniel three times. It was special to beat him.''
The other Dunedin-based bowlers to win 20 or more centre titles are Gary Flewitt on 32, Bob Cowan on 23, French on 23, Lyn Rance on 21 and Kevin Darling on 20.
Rance was inspired to win another title after Cadogan caught up with her on 20 titles before the triples final started on Sunday afternoon.
She teamed with fellow Green Island members Max Grey and Stu Alderton to beat Vauxhall's Tony Hosken, Mike Harte and Peter Earl 13-12.
It was Rance's 21st centre title, the first for Alderton and the second for Grey.
Vauxhall led 8-4 after five of the 10 ends but the game changed when the skilled play of Rance helped Green Island to score three shots on three of the last five ends to win the game.
It was the 10 time Earl had finished runner-up in a centre final.
