Suburbs won the under 11-13 grades last year.
The under 9 title was won by the Wanganui East Phoenix, who went on an undefeated run across their six games.
A notable entry to the event will be Wanganui Athletic's own all-girl team the Athletic Starlets, the only all-female team in the tournament.
WAFC tournament organisers have been working hard to lift the standard and improve on last year's efforts.
This year will see 13 qualified referees, medals awarded to both winners and runners up, and running results posted as they come in.
Event manager Gary Johnston is pleased with the 50-50 mix from local and visiting sides.
"For kids that aren't involved in representative teams, this tournament is a great chance to size themselves up against their peers in a higher level of competition.
"The tournament was open to all players, so every kid had an opportunity to be involved."
The Wanganui Athletic FC leadership is hoping to make the tournament an established event on the football calendar.
All rounds kick off at 9am, with a prizegiving ceremony to be held at approximately 4pm.
