Gisborne, cheered on by whānau, friends, schoolmates and other teams, stunned Tauranga 24-12 – the only loss the Bay of Plenty side suffered over the competition.
Cranston said it was more about Gisborne playing to their abilities rather than a shock, along with Tauranga “probably taking us a little bit lightly”.
The win put the home team into a crossover game against Hastings on Sunday – the Hawke’s Bay boys winning 22-10.
That dropped Gisborne into the seventh-eighth playoff game against New Plymouth.
They came out firing on the hard, dry Rectory surface, which produced plenty of grazes and bruises over the tournament.
Gisborne powered to a 20-7 halftime lead and were always in control.
Cranston said Kahurangi Leach-Waihi, who scored a double in the match, and Quaydon Chaffey-Waihi were their standouts.
Tauranga bounced back from their loss to Gisborne to beat Palmerston North 24-10 in their semifinal, then defeated reigning champions Hamilton 19-10 in the final.
They added the sevens crown to their Super 8 15s title for which they also beat Hamilton (37-0) in the final.
Gisborne placed fifth in the years 9 and 10 grade at the Super 8 sevens.
They ended the tournament positively after losing their three pool games.
Gisborne beat New Plymouth 12-10 in their crossover game, then Palmerston North 21-19 in the playoff for fifth and sixth.
Rotorua defeated Tauranga 17-12 in the final.
