With just five races remaining, the home crew. captained by Peter Burling, had resumed racing with a 5-3 lead, having won both races on the previous day on the inner Hauraki Gulf off Auckland.

Both boats were AC75 class high-performance foiling monohulls, a class specifically designed for this challenge for the oldest international sporting trophy, which first took place in 1851.

This was the fourth time that New Zealand had earned the "Auld Mug".

The New Zealand Herald reported that the New Zealand Government has already committed funding towards the next America's Cup defence.

Future funding will be, however, on the condition that the next defence will be held in New Zealand in four-years time. 

Prime Minister Jacinda Ardern congratulated the Kiwi sailors just minutes after skipper Peter Burling led his crew to victory.

"On behalf of all of Aotearoa I congratulate Grant Dalton, Peter Burling and the whole team, those on the water and off it, for their achievements," Ardern said.

"Peter Burling and his crew of skilled sailors showed what they were capable of in all conditions, highlighting the tactical brilliance and sheer hard work of everyone involved.

"Following a hard year, Team New Zealand provided such optimism and excitement. I know with all the international limitations that COVID created this wasn't the competition they expected, but they've made us so proud."

Going into the 10th race that had been twice delayed by wind changes needing a victory to settle the best-of-13 series, the home boat led its Challenger on every leg, crossing the line 46 seconds in front to spark jubilation within the race village on the shore.

The ninth race had been closer, with Luna Rossa holding a narrow lead through almost five of the six legs of the race.

But Team New Zealand, who had remained with 100 metres, moved into the lead to take a 6-3 lead.
