Hataji produced a birdie at the 12th hole to grab the sole lead at the $1.22 million event co-sanctioned by the Asian and Australasian PGA Tours, before Hend caught up with him at 17-under after the 17th hole at Queenstown's Millbrook Resort.
With a playoff looming, Hataji managed par on the final hole but Australian Hend, who was superb on the greens throughout the day, missed a four-foot putt for par which gifted the title to his Japanese opponent.
Hataji finished on 17-under for the tournament while Hend, who started the final round tied for the lead with compatriot Matthew Griffin, managed 69 to settle for second place, with a group of three finishing behind him in joint third.
