Australian Su Oh is four shots off the pace after the opening round of the LPGA's New Zealand Women's Open.
Oh made six birdies in a three-under par 69 to be tied for 11th after Thursday's action at Windross Farm Golf Course.
Katherine Kirk carded a 71 to be at one-under with Sarah Kemp a shot further back after an even-par 72.
Stacey Peters and Sarah Jane Smith are at one-over while a number of fellow Aussies have work to do on Friday to make the cut.
Meanwhile, England's Jodi Ewart Shadoff and world No.12 Brooke Henderson snared 15 birdies between them to be joint leaders after seven-under par rounds of 65.
"It was a great start for me and exactly what I was looking for to get on top of the leaderboard early," young Canadian star Henderson said.
"I know with the conditions today that the scores were going to be really low. Hopefully I can continue the trend in the next days."
Ewart Shadoff got the putter running hot, somewhat to her surprise.
"I didn't expect to play as well as I did. My last tournament, I missed the cut at the Evian," she said.
"I putted well today. I think the greens are great."
Ewart Shadoff and Henderson are one shot ahead of Spain's Belen Mozo and Amy Boulden of Wales with another trio tied for fifth.
New Zealand's top golfer Lydia Ko finished with a two-under 70, to be tied 20th.
"There is a lot of golf to play, I have to stay positive and have fun," world No.8 Ko said.
