The Junior Paddle Ferns started the competition as underdogs, Winton told the official website.
"We're a new team and being here in these surroundings in France, winning the bronze medal, with so much pressure, is just amazing.
"The crowd was so loud I kept telling myself, there is no sound, it's all right," she says, delighted to have clinched the game that counted most against Great Britain. "In Europe the teams have so many tournaments throughout the year compared to us, we've got [fewer] than five. In the end it was a great experience."
New Zealand competed at three warm-up tournaments in the Netherlands, Belgium and France en route to the champs.
"I want to make the senior women's team to the Oceania in Australia," says Winton.
In the senior men's grade, the Kiwis finished seventh among 24 teams with France, Germany and Spain getting on the podium.
The senior Kiwi women had to settle for fourth among 20 contenders, missing out on a podium place to Germany, France and Great Britain.
