ERRON MAXEY continued his hot form scoring twenty two points, while fellow American JOSH PACE collected 19 points and nine rebounds.
Pistons guard TAI WEBSTER had a game high 23 points, but it was another slow start for the visitors as they were down 15 at half time.
Nelson would extend their lead to 19, but a late rally by Waikato in the fourth quarter, managed to close the gap to only six points with still five minutes remaining.
After a time out, the Giants regrouped and put a halt to the Pistons momentum, pushing their lead back up to double-digits, sealing win number five for the season.
League leading rebounder ZACK ATKINSON had a solid double-double of 14 points and 11 rebounds, but Giants MIKA VUKONA replied with fourteen rebounds of his own.
It is the Pistons fifth loss of the season and they will play their fourth straight road next week, which will be against the Mountain Airs, who have had back to back twenty plus point losses.
It was not the start to the double down south the Airs were hoping for, as the Sharks outplayed them on every facet.
Sharks import Brian Conklin
(198-F-89, college: St.Louis
) was impressive scoring 31 points and only missed two field goals (12/14 FG), while Breakers development player REUBEN TE RANGI had 25 points, making four of eight three pointers.
Round Three player of the week KENNY GABRIEL had limited minutes due to foul trouble, eventually fouling out in fourteen minutes, only scoring five points.
It was also a tough night for JACK LEASURE who was held to 11 points, going 5-for-15 from the field.
Taranaki will now move on to Dunedin to face the red hot OCEANAGOLD NUGGETS tomorrow night, while the Sharks will have a night off before they also travel to play the Nuggets in arguably the game of Round Five.
