As it happened: Lydia Ko at the NZ Women's Open - Round 1

All the action from the opening round at the New Zealand Women's Open.

Lydia Ko teed off early as she targets her first LPGA Tour win of 2017.

Ko last won a golf tournament in July 2016, but two top 10 finishes this month have buoyed her ahead of her home event.

She fell from the world No.1 spot on June 12 - she's currently No.8 - but has had nine top 10 finishes and earnings of US$834,899 this year, including a tie for third at the Evian Championship major 10 days ago.

Speaking after yesterday's pro-am the 20-year-old said the biggest adjustment to make will be for course conditions.

"This is a new golf course, so it's not like I know it with my eyes closed.

"It's been good to play in different weather conditions over the last few days. I was out there in the rain and wind in the afternoon [yesterday], and today when it was calm.

"The weather will be a huge factor here because there are not that many trees or things to block the wind, which could make it tricky."

Ko said she had rebuilt her confidence in recent weeks.

"I've been struggling for the last few months so it was nice to have those [top 10] finishes coming here.

"I don't think there's a miracle [turnaround] out there. It's hard when you know the pieces are there, but don't really know what's going on. The top 10 in Indianapolis [at the Women in Tech championship] gave me confidence for Evian."
