Lydia Ko believes three rounds of three-under par will be enough to secure her the New Zealand women's Open title for a second time.
The 2013 champion is hot favourite for the tournament beginning today at Clearwater.
World number one Ko says there's an obvious factor that will decide the target.
"It just all depends on the wind, sometimes the wind direction" she said.
"Ten under is a pretty solid score the last couple of years."
