In the final, Three Kings United took an early lead through a third-minute goal from Luiz del Monte.
Three Kings dominated for much of the early part of the match, but higher-ranked Olympic fought back, and a header just before the half-hour mark from Mickey Malivuk levelled the scores at 1-1.
In the second half Olympic had the upper hand, and eventually took the lead through a 75th-minute penalty taken by Raf de Gregorio.
Three Kings attacked strongly during the last few minutes of the match but were unable to produce an equaliser.
The winner of the 2009 Jack Batty Memorial Cup was Raf de Gregorio of Wellington Olympic.
