Warriors CEO Cameron George says the club’s current general manager of football Craig Hodges was leaving to pursue coaching opportunities in Australia.
George said McFadden, 44, was keen to step away from coaching at NRL level and into recruitment and development.
“We’ve invested heavily in development and pathways while being based in Australia for the last three years and we have even bigger plans in this space with our full football operation coming back to New Zealand from next season.
“Part of his role will be to identify and mentor young coaches in our system.
“Cappy also has a relationship with (new head coach) Andrew Webster from the days when he was head coach here and Webby was an assistant coach.”
McFadden has spent the last four seasons with Canberra, a period which has seen the Raiders reach the NRL grand final in 2019 and the preliminary final in 2020.
