Lydia Ko was five shots behind the clubhouse leader as she turned to play the back nine in her opening round at the New Zealand Open at Clearwater.
The teenager birdied the 12th but three holes later signed for a bogey 5 after pulling her drive left on the 15th.
She parred home to make the turn in even par 36, the same as her teenage playing partners Charley Hull and Su Oh.
Denmark's Nanna Koerstz Madsen and the USA's Samantha Troyanovich were the clubhouse leaders after both went five under in the morning. Madsen was bogey free while Troyanovich had one bogey around six birdies on the fine putting surfaces.
Hannah Green, an Australian amateur and American pro Beth Allen led early before being caught as the winds kept gusting in from the north-east.
