Day was also quick to praise Rotorua Lakes Council for its help in staging the tournament.
It was the second time the competition had been held since taking over from the Western Heights High School Invitational Tournament last year.
The number of teams was up this time around, with 19 boys and girls teams playing over the weekend.
Western Heights High might have been hoping to repeat their dominance of last year's tournament, when both their boys and girls squads walked away with titles.
But after not entering a girls team this year, the boys were beaten 2-0 by Gisborne in Sunday's fifth and sixth place playoff.
They had previously lost 1-0 to eventual title winners Massey High School earlier in the competition.
Massey took home the title after beating St John's of Hamilton 1-0 at the International Stadium yesterday.
In the girls tournament final, Trident beat Hilcrest 1-0 to take home their winners' medals.
Before the weekend's games kicked off, Day said one of the main goals of the tournament was to boost the profile of Geyser Football Club.
The club was established in 2013 to help young footballers in Rotorua.
