A day after pugnacious Australian skipper Jimmy Spithill steered the defenders Oracle to their first win of the series, helmsman Peter Burling and New Zealand reasserted their dominance.
Sailing professor Mark Orams joined Larry Williams to discuss how both teams are looking ahead of tomorrow's racing.
"We said last night we had a fair few things to work on and we addressed them today", said Burling.
He won Olympic gold in Rio previous year in the 49er skiff class with fellow crew member Blair Tuke and has brought a youthful confidence to New Zealand's campaign to regain the "Auld Mug", which was first won by the schooner "America" in 1851.
Asked if the complicated technology that modern Cup teams rely on had let Oracle down, Spithill refused to make excuses.
NZ are two wins from winning the America's Cup after a super display in race seven.
"We're a pretty tough bunch", Burling said.
Burling showered his jubilant team mates and support crew with champagne after their sleek black, red and white catamaran crossed the line, having dominated the race from early on.
As one of Team New Zealand's much vaunted cyclors, Sullivan's job is to produce the hydraulic oil that powers the boat's high-tech foiling and wing-sail systems.
Burling, 26, bested Spithill in the pre-start of both races, and the U.S. couldn't recover either time.
One certainty for the other teams thinking of the next campaign is that Italy's Luna Rossa, which is backed by the Italian luxury goods group Prada, has been chosen as the Challenger of Record for the 36th America's Cup.
"We're just excited we've got the opportunity to do that now". We were disappointed to give away a race yesterday, but we certainly made up for it today.
The clincher could come Monday, when two races are scheduled.
Helmsman Peter Burling and Team NZ sit on match point, within one win of lifting the America's Cup off archrivals Oracle Team off Bermuda. "From then on it was very hard to catch them once they got their noses ahead".

"We thought we would be able to pull a maneuver off but clearly we couldn't, it was a big mistake", admitted Spithill on the poor pre-start.
By gate two that lead was already up to 24 seconds and Spithill chose to split the course, a decision that appeared to pay dividends as the gap started to decrease, but a penalty on leg four as Oracle Team USA sailed outside the boundary effectively ended their hopes in race eight.
New Zealand snatched back the momentum after the United States of America notched their first win of the series on Saturday.
The New Zealand crew had been on a mission to wipe out the hurt inflicted when an 8-1 lead was overhauled by the USA team.
