The tournament will stage more than 130 games over three days with the main draw semifinals, at 9.30am, and the final, at 12.30pm, moving to Bluewater Stadium on Monday.
The pool games will be 25 minutes each way and the final 30 minutes. The quarterfinals tomorrow from 3.30pm will round off pool play.
Birkenhead United are defending champions after the Paul Hobson-coached side pipped Neil Emblem's Western Springs 1-0 in a final last year that threatened to go into extra time.
It was Birkenhead's second consecutive tourney crown.
In the all-Auckland satellite final last October, Manurewa beat Forrest Hill Milford 5-4 in penalties after a scoreless hour-long regulation time. Both sides gained promotion to the main draw this year.
The tourney has provided a platform for some young talent to gain international reputations.
Leeds United player Chris Wood and Wellington Phoenix's latest signing, Kosta Barbarouses, as well as former Napier-born All Whites goalkeeper Mark Paston and midfielder Chris Jackson are among the pedigree players who have graduated from the Park Island tourney.
