The new deal will keep Lagerwey at the club until the end of the 2014 season.
“Garth has been one of the major forces behind our successful rise on the field, which has also had a positive effect on our overall business operation,” said RSL president Bill Manning on the club’s official website.
“He is talented, well thought out and in my opinion one of the sharpest young minds in the game today.
“It was important to me and our ownership that we ensure for our fans a perennial championship contender, and that we reward Garth for his success and guarantee consistency in the front office.”
