Starling Park Sports Club is a partnership between the Waitakere Bears Softball Club and the Ranui Swanson Football Club, based in a new sports club building opened in 2011.
A year later work began on an artificial turf and floodlights for the full-sized field and softball diamond.
The Auckland Council earmarked $450,000 for the work while the club paid $750,000.
However, council parks, sport and recreation manager Ian Maxwell said that as a result of the theft, the contractor for the artificial turf work, Wilkinson Civil, was not paid by the club for its services.
Reeves is a former coach of the Waitakere Bears top mens team, and according to the Starling Park Sports Club's website, won the club's "gentleman's cup" in 2009/10.
