Team New Zealand skipper Peter Burling's mum Heather says the team's win was overwhelming and a huge relief.
She said the team had been amazing.
"They're such a lovely group of sailors that have grown up together and sailed together for so long.
"I think they're all just really good mates, they just enjoy each other's company and they're all sailors ... they're all really, really, really, really good sailors and they all know that it just doesn't always go your way and they're all pretty honest. You know, if you've made a mistake you own that mistake, you look at how the whole team can do better, you don't try to blame anyone else.
"That's just who they are and who they've been for a long time now, you know it's their second America's Cup together."
Team New Zealand had a confident lead over Luna Rossa on every leg in race 10, although the race was delayed twice starting half an hour later than expected, the defenders secured an early lead against their Italian rivals.
Heather Burling said this was one of the easier races to watch.
"I like leading from pretty much the beginning," she said.
