"From a shooting perspective, I'm really looking forward to working with Marg and having the opportunity to work with an Australian coach was also a strong pulling point," she said.
Halpenny is also relishing the prospect of teaming up with England shooting import Jo Harten again, the pair spending the 2012 season together at the Tactix.
"It's great to see Ellen returning to Magic for 2014 after really taking a step up this year," Fitzgerald said.
"Given the opportunity of regular court time in 2013, Ellen showed she is capable of competing well at this level and I believe can continue to improve considerably on her game.
"There is potential for her to form a strong combination with our other shooters and she is able to switch from goal attack to goal shooter when required. With the confidence of a strong season behind her, Ellen is primed to work hard for even better things in 2014."
Born in Australia to New Zealand parents, Tairi, 25, came through the Australian system and three season with the Sydney Swifts (2009-11) before switching her allegiance and opting to ply her trade on this side of the Tasman.
The move paid off handsomely for the former Australian under-21 representative after her recent naming in the Silver Ferns team for the upcoming five-test Constellation Cup series against Australia followed by a three-test series against Malawi.
Former Swifts mentor, Fitzgerald is looking forward to reuniting with Tairi at Magic, believing she is on the verge of developing into one of the game's top midcourters.
"I have always admired Courtney's ability to feed the shooters, a skill often overlooked when selecting centre court players in today's game," she said.
