Similarly, Harrison was a Venus flytrap whenever the ball came within grasp, notching seven deflections, four intercepts and three rebounds.
The sides were locked at 13-13 after the first quarter before the Mystics sneaked ahead 26-24 at halftime. The Magic seized a 36-34 advantage late in the third quarter which they extended late.
Little differentiated the shooting ends. Mystics goal shooter Cathrine Tuivaiti was the most accurate. None of her 16 shots missed.
However, the sheer volume of possession was enough to turn the match in the Magic's favour. They had 58 shots on goal compared to the Mystics' 49.
With the ANZ championship set to become defunct by season's end, the contest was also played in the shadow of speculation as to where players might ply their futures.
With the prospect of an extra Netball Northern franchise on the horizon, New Zealand derbies will offer extra incentives for local players as the competition advances.
The result takes the Magic to four points on the table, overleaping the Central Pulse who play the Southern Steel on Monday.
The Mystics will stay second among the New Zealand teams unless the Mainland Tactic overcome the New South Wales Swifts tomorrow.
