Lydia Ko's victory in the Canadian Women's Open is the most significant event in New Zealand women's golf, according to the sport's national governing body.
Ko, who's 15, shot a five-under par 67 to win by three strokes and become the youngest winner on the LPGA Tour.
The chief executive of New Zealand Golf Dean Murphy says no New Zealand woman's ever won on the Tour previously and while it's not unexpected it's a stunning achievement.
Murphy believes the victory will give the sport and enormous boost.
The victory in Vancouver is the second professional tournament win for Ko.
She became the youngest golfer to win a professional event at the New South Wales Open in January, when she was 14.
Ko, the world's top ranked amateur, won the US Amateur championship earlier this month.
Murphy doubts the win will change her future plans with Ko having said she's in no rush to turn professional having talked about gaining a US University scholarship.
He says her goal is to play seven to 10 professional events a year so that when she does turn professional in a couple of years she'll be well prepared.
