"I said all along that I still have something to give and this role is perfect for me right now."
It is not the first time McFadden has been open to working with Kearney, with the 38-year-old having been briefly appointed to an assistant coaching job with the Kiwis in early 2014.
The arrangement was short-lived, however, when McFadden was appointed Warriors coach and took over from Matthew Elliott after five rounds of the 2014 NRL season.
Kearney downplayed any perceived awkwardness around him retaining the man he effectively usurped on his staff and said it was an obvious decision to utilise McFadden's skills and experience.
"He was a logical choice," said Kearney. "I certainly don't have a problem linking up with Cappy [McFadden]. He doesn't have a problem with it.
"[He's] been with the group for three or so years and done some great work there so it was an easy choice and I'm looking forward to working together with both him and Stacey."
McFadden still harbours ambitions to be a head coach and said the new coaching structure would enable him to further develop his skills. He also believed his time in the big seat made him an ideal candidate to provide Kearney with the right assistance.
"The experience I've got as a head coach is invaluable for me and it will make me a better assistant coach to Stephen. I know first-hand the support a head coach needs and intend to be fully aligned with Stephen and make sure I do a really good job for him."
Central to Kearney's plans will be back-rower Simon Mannering, who last night was named Player of the Year a record fifth time in his 12-season career at the club. The 30-year-old is the only player in the club's history to win the premier award more than twice, Steve Price earning the accolade in 2006 and 2007 and Ben Matulino honoured in 2012 and 2015.
Hooker Nathaniel Roache was Rookie of the Year, halfback Shaun Johnson the winner of the People's Choice Award and retiring Radio Sport commentator Allen McLaughlin was a popular recipient of the Legacy Award.
