"I'm just ecstatic - the girls played their hearts out tonight, I played my heart out - I'm so happy to get those two points," she said.
"We train our butts off every week and nice to finally put that out on court for the first time this year."
The Magic today welcomed key midcourter Grace Rasmussen back into their line-up for the first time since the Silver Fern's fleeting appearance in round one, during which she was forced from the court after a flare up of a calf injury. Rasmussen's absence has had notable impact on the Magic's attack end, with her vision and timing sorely missed.
The return of Rasmussen also saw a return of some level of fluency to the Magic attack, with Harten in particular looking a lot more comfortable with Rasmussen supporting her on the circle edge.
Leading 17-15 in the opening quarter, it looked like the Magic of old had returned. But attacking wobbles returned to haunt their game in the second spell, as the hard-working Tactix defence did all they could do disrupt the visitors' rhythm.
Down the other end the young Magic defence struggled to have the same impact against the outstanding shooting pairing of Mwai Kumwenda and Bailey Mes, who have proven difficult for even the most experienced opposition to break down.
With the Magic's shooting accuracy slipping to just 72 per cent in the first half, the Tactix won the second quarter 17-10 to surge ahead to take a five-goal lead at the long break.
A change to the Magic shooting end in the third quarter, which saw the introduction of Paula Griffin in place of Malia Paseka, helped spark a revival from the visitors in Nelson, with Griffin helping to create more space for Harten.
The Magic drew level at 39-all with just over five minutes left in the third quarter, but a late run from the Tactix saw them restore a 46-43 lead by the final turn.
In a tense final quarter, the defining moment came with just over two minutes left on the clock, when the Magic capitalised on an attacking error from the Tactix, taking a one-goal lead from the resulting centre pass.
In this afternoon's earlier match-up, the well-drilled NSW Swifts wore down the Melbourne Vixens 59-51 after a tightly contested opening half.
The Mystics and Pulse will wrap up round seven action when they meet in Auckland tomorrow night.
