New Zealand won the final fleet race at the Cascais AC45 World Series regatta at Cascais, Portugal, overnight.
Dean Barker - who sailed with Glenn Ashby, Ray Davies, James Dagg and Winston Macfarlane - described the win as "fantastic".
"Two years to go," he told TVNZ in a reference to the planned America's Cup, but added: "There's still a lot of work to be done".
The New Zealanders stumbled in the previous day's match racing final, losing to Oracle 4 in the America's Cup class World Series regatta.
In the fleet race early today, the team appeared to have returned to the form which won it the preliminary races last weekend.
