Guard Micaela Cocks has guided the NZ Tall Ferns home 75-72 over Japan to finish tied for the best record at the William Jones Cup.
Their 4-1 record ties them with Japan, who were unbeaten coming into tonight's fixture in Taiwan.
"It was a truly competitive game, a game of good execution for both teams at both ends of the court," said head coach Kennedy Kereama.
The two sides couldn't be separated at halftime at 37-37, but 13 third-quarter points from Cocks helped the Ferns take a hold of the match after the break, as they pulled out to a nine-point lead with a quarter to play.
Japan, who attended last year's Rio Olympics, threw everything at the Kiwis in the final stanza, but they held firm to close out the three-point victory.
