Even though Northland's men's and women's NHL sides were playing off for seventh and eighth, Northlanders still featured for Auckland sides in the top play-offs.
A goal from Northland's Dwayne Rowsell for Auckland in the final helped his side to a draw, before they went on to win in a dramatic penalty shoot-out win over Southern to take home the Challenge Shield in a replay of last year's final.
Rowsell, 22, scored midway through the second half on Sunday to put Auckland back out in front with a well worked penalty corner flick but Southern responded immediately with a goal of their own, Jason Dungey levelling the score and sending the game to fulltime at 2-2.
With both periods of extra time proving fruitless for both teams, Auckland stamped their authority to win the penalty shoot-out 4-3 and clinch their third straight NHL title.
Earlier in the day, a Samantha Harrison double helped Auckland women defeat Canterbury 4-nil to win the bronze medal.
