Kobori, also the reigning South Island amateur champion, held a two-shot lead after the opening round on Saturday with a four-under-par 67.

Yesterday, in slightly damp conditions, Kobori’s metronomic performance continued.
A third straight 67 gave him a three-round, 12-under-par total of 201.

She fired rounds of 70, 73 and 71 on the par-73 women’s course for a five-under-par total of 214.
Otago No 1 Sumin Kang (Wakatipu) was second at three-over, recovering nicely after blowing out to 77 in the first round, adding rounds of 74 and a tidy 71.
