Barker was part of Team New Zealand's defence in 2000, taking over at the helm from Russell Coutts in the last race. He was then skipper in 2003 when Coutts' Alinghi took the Auld Mug from Team New Zealand and an unsuccessful challenge in 2007. His final campaign with Team New Zealand was in 2013 when the Kiwi team gave up an 8-1 lead to lose 9-8 against defenders Oracle Team USA.
After leading the Japanese challenge in 2017, Barker will sail with the challenge out of the New York Yacht Club in 2021.
"To sail for the New York Yacht Club is a special thing, and I'm really thankful for the opportunity to be involved," Barker told Newsroom.
"I love the thrill of the sailing and the racing, and all the elements that go with it," he said of the America's Cup.
"Developing a team, designing and building a boat, and all the challenges that you're faced with. It's not as simple as just putting a boat in the water and going sailing. It's intriguing and enjoyable at the same time."
