Striker Stephen Jenness scored a double in his 100th test as the Black Sticks stormed to a 5-1 win over Japan in the third and final match in Tauranga, claiming a 2-0 series win.
Wednesday night's opening game was drawn.
The game was played in calm conditions, having been rescheduled from Saturday night due to the incoming Tropical Cyclone Lusi.
The Black Sticks were dominant all over the turf and played their most cohesive and impressive game of the series.
Along with Jenness' double, Hugo Inglis also scored a brace of goals while Simon Child also added to the tally.
Head coach Colin Batch says it was pleasing to finish with a clear series win.
