The composite team of Graham Hood, Lloyd Gallop, Matthew Gallop and Forsyth had a decisive 18-11 win over the North East Valley combination of Stephen O'Driscoll, Jim Scott, Shaun Scott and Terry Scott in the final at the Taieri headquarters green.
It has been a successful New Zealand open championships for Forsyth and his third, Matthew Gallop, who also finished runners-up in the pairs.
Forsyth, the winner of back-to-back singles titles in 2003-04, needed the win to cement a skip's place in the Black Jacks.
"There is a spot for anyone ready to step up," Forsyth said. "I think I've done that over the last 10 days."
Forsyth displayed tactical nous as a skip throughout the competition by shifting the mat around and varying tactics.
"I was very happy by the way I managed the side," Forsyth said. "I have done as much as I can to convince the selectors that I can skip a team at the top level."
Forsyth has been known primarily as a singles player and filled that role at World Bowls in 2008 and at last year's Commonwealth Games in Delhi.
But he has honed his skills at other facets of bowls since shifting to Australia three years ago and playing in the tough Sydney league.
He has played bowls for 15 years and understands what is needed to be successful in the international arena.
"It is just a matter of knowing what time to be aggressive and when to sit back," he said.
Forsyth displayed a mastery of tactics in the final yesterday.
He was helped by Hood and Lloyd Gallop who dominated the front bowls and had the better of their opponents.
"They set a good platform for Matt and myself," Forsyth said. "There was only one end when we looked like dropping more than two shots. We just tried to keep things tight."
The North East Valley skip Terry Scott, was forced to play drives and upshots from early in the game. He was forced to play rescue shots from the fifth end and was on target for seven of his 14 drives and run shots.
In contrast, Forsyth played most of his drives late in the game and hit five of his nine runs and drives.
"They were too strong up front and overall they outplayed us," Terry Scott said. "They had shots on the head and we had to play aggressive shots most of the time."
There were only two ends in the game when more than two shots were scored and both went to Forsyth's team.
They scored a four on the sixth end to get back into the game to take the lead for the first time, 6-4. They never let it go after that.
Terry Scott explained why he did not drive on the sixth end.
"It was not set up for the drive," he said. "We thought we could recover the shots with draw bowls but we struggled on that end. It wasn't a target for driving and we would only been able to take one bowl out and it was in the early stages of the game".
Another occasion came on the 14th end when North East Valley was in catch-up mode and Terry Scott was forced to drive when down on the head but it did not go to plan and they dropped three.
"Terry was unlucky," Forsyth said. "He took out his own back bowl. Otherwise he would have had the shot".
It could have been a 12-8 deficit for North East Valley, instead of 15-7 with four ends to play.
"If you get numbers like that on two ends you should be able to manage the rest of the game," Forsyth said. "We just had to play conservative bowls after that. It is not easy to score big points against good sides."
Forsyth's composite team had a much tougher task in the semifinal against Alistair Keith (Taieri) before winning 15-12, on Saturday.
He showed a touch of class on the final end when he drove the jack into the ditch for two shots with his last bowl when Keith had two winning shots on the head.
