Sunday's leader, Oracle Team USA, came in to the day on the back of a perfect scoreline in the first two races. But today was a different story.
Two fourth place finishes dropped the Cup holders to second place.
"We're disappointed," said skipper Jimmy Spithill.
"We were having a very difficult time speed-wise and with our technique in the lighter winds. We felt good when the breeze was up and we were on the foils. So we have to get back to work."
In the first race of the day the local favourites Artemis Racing got off to a strong start and by the bottom mark had picked up a puff which eluded the fleet and were away to take a significant win to put them right back in the hunt for the overall win after an indifferent first day.
But it was the order of the following boats in race one which really set the foundation for a dramatic final race.
A pre-start penalty, which, resulted in Team NZ being last off the start line they managed to graft their way back through the fleet to cross the finish line in second, ahead of Ben Ainslie Racing and Oracle Team USA.
The mathematical equation of this meant all three teams, Team NZ, BAR & Oracle were all tied on points, and Artemis Racing just two points adrift setting up what was effectively a winner takes all final race between the four teams.
Oracle had a strong start, and a good lead by the bottom mark two. Team NZ rounded in third place 100 metres behind the leaders.
The key to the race, and effectively winning the regatta came on leg three, when Team NZ split from the leaders at the bottom gate.
"We planned that from a long way out, we had a long chat amongst the guys and took the right hand gate even though it looked pretty bad for a long time, but we knew we were going to have a couple less tacks and have better pressure for that whole upwind but also get that right hand side at the top," said Burling
Converging at the top mark, Team NZ rolled the Americans to round the top mark in front closely in front of Softbank Team Japan.
From this point on Glenn Ashby and crew extended their lead, never comfortable, but in control.
"There were plenty of snakes and ladders out there, plenty of opportunity and also room for going backwards quickly as well. But we were really happy with the way we sailed but a fantastic result for us," said Ashby.
Team NZ are the only team to have been in the top three in every race of the 2015 World Series, and as a result have a seven point lead overall in the series, ahead of Land Rover BAR & Oracle Team USA.
