Tonga were impressive in the opening term and trailed by just two goals at the first change, leaving a “frustrated” Diamonds coach Stacey Marinkovich to rev up her side on the bench.
And the speech worked as the Diamonds went on a 10-goal run to open the second, forcing Tonga to bring Tuivaiti onto the court at goal shooter.
The former Silver Fern and Samoa representative brought the fireworks with look-away balls and over the shoulder passes to excite her teammates and crowd.
