Now ranked 11th in the world, the 20-year-old Kiwi carded back-to-back rounds of one-under 71 at the Sentosa Golf Club, and sits 10 shots off the pace set by American Danielle Kang.
Ko's second round was an up-and-down affair, with five birdies offset by four bogeys, and leaves her in a tie for 27th with eight others.
Kang holds a four-stroke lead from compatriots Nelly Korda and Marina Alex.
