The world No 1 was one-under through 15 holes today, which left her in a share of 32nd at four-under for the week before play was suspended due to darkness.
Ko is six shots back from leader Gerina Piller (-10) but a host of players still need to complete their third rounds, which will further shape the leaderboard.
World No 2 Inbee Park, who trails Ko by a tiny margin in the global pecking order, is in share of eighth at eight-under and depending on where she finishes, the Korean could take back the top billing from Ko this week.
Following this weekend's tournament, Ko will play in Melbourne before heading to Clearwater to contest the New Zealand Women's Open in Christchurch from February 27-March 1.
Meanwhile, Danny Lee has slipped to a share of 42nd at the Farmers Insurance Open on the PGA Tour in San Diego.
Lee, the only Kiwi to make the cut this weekend, carded a one-over 73 during his third round and is at two-under for the tournament, seven strokes back from co-leaders J.B. Holmes and Harris English.
