The prolific goal scorer has slotted 3678 goals from 4020 attempts with an accuracy rate of 91.4 percent over the past five seasons with the Steel.
Her last season with the Steels was the franchise's best, going through the ANZ Premiership unbeaten before also winning the Super Club tournament in Nelson.
"I've grown so much - not only within my career but also personally," Fowler-Reid said.
"My game has changed tremendously ... I have many tricks up my sleeve now to keep defenders thinking. I'm not a one-trick pony anymore."
She was "incredibly grateful" for the opportunity to join the Steel ranks in 2013.
"It has changed me and it has grown me so much and the opportunity to come over to New Zealand is something that I really appreciate. The Steel have had such patience with me and supported me so much in feeling like I'm at home," she said.
The competitive nature of the inaugural Super League was a definite drawcard for Fowler-Reid.
"I'm impressed. I feel the teams over there are tracking good and there's some pretty exciting players over there. I know it's going to be a good league to ply my trade," she said.
"There's some tough defenders but I've played them before so I know them. They may not know me because I think I've evolved in the past season so it will be a good thing for me to go in even stronger."
A battle against the 2017 champions the Sunshine Coast Lightning, coached by her former mentor Noeline Taurua, also loomed.
"I look forward to playing against her team and I know she's going to have her defenders pull out all the stops on me but I'm sure I'm going to have some stops myself."
