New Zealand golfing star Lydia Ko's second round four-under par 68 has left her in prime position to challenge the leaders, at the LPGA's KEB Hana Bank Championship in Inchoen South Korea.

Ko was bogey-free on Friday (NZ time), dropping four birdies to leave her just two shots behind the four leaders.

Americans Danielle King and Charley Hull are joined at the top by South Korean Sung Hyun Park and Thailand's Ariya Jutanugarn - all on eight-under.

Ko is an a tie for fifth alongside opening round leader Nasa Hataoka from Japan, as the Kiwi looks to improve on her 16th spot in the LPGA rankings.
