"There's a bit of pressure there but, after moving to the Magic, that pressure's been taken off me a little bit," Harten said. "Now I'm just enjoying playing and trying to be a normal member of the Magic."
Harten is in the unique position of being an English player in a Kiwi team who is coached by an Australian in Julie Fitzgerald, who led the Magic to the preliminary final during her first season at the franchise last year.
"It's a great mix and I'm loving it," Harten said.
Last year was good to Harten on a personal level, too, as she shared the league's MVP award alongside Swifts midcourt dynamo Kimberlee Green.
Fitzgerald said Harten, who has scored more than 1500 goals in the competition, had developed into a crucial member of their side.
"She's a true professional, a leader within our group - a real character and an outstanding shooter."
Today's game is crucial to the Magic's push towards the playoffs as they try to leapfrog the Steel on the ladder. Both sides have seven competition points but the Steel edge the Magic on goal percentage - the Mystics lead the New Zealand conference with 12 points.
A win today for the Magic would allow them to push towards confirming a playoff spot.
"We really want the two points and we want to win but I think, more importantly, we want to play some good netball," Harten said.
"For us, it's just about nailing down the basics and trying to have fun. That eludes us a bit when we get so tight in the season but playing for each other is a big key for Sunday."
Harten will also get the chance to play without fear against Australia and New Zealand at August's World Cup in Sydney.
