Rotorua Boys' High School are the Bay of Plenty secondary school rugby champions after an at times brutal dismantling of traditional rivals Tauranga Boys' College at Nicholson Field.
The hosts led the match 6-5 after 15 minutes, then began to fall off first-up tackles to find they were not often afforded the benefit of a second opportunity.
Rotorua Boys' took possession of the gain line with and without the ball, and looked legitimately scary at times when they stacked big ball carrying forwards in a backline already not short on size.
The floodgates opened with a spectacular try from highly-rated under-19 touch representative Ngarohi McGarvey-Black.
The left winger was given an inch down the touch line and took about 60m - skipping around a defender before toeing ahead and beating the cover to regather and score.
First five-eighth Maake Taulahi, one of a number of Rotorua players occupying a different position than listed in the programme, then decided it was time to take over.
The 19-year-old repeatedly chopped off his left foot inside his own territory before surging through and putting long-striding winger Latu Vaeno away to score.
Giant No8 Viliame Tosi - who is still eligible for Under-16s despite the fact he might struggle to squeeze into an under-16 stone competition - then put his mark on the match.
Quick ball off the top of a 5m lineout found its way to the big youngster on the crash, and he found his way over the top of the defence to effectively decide the contest at 26-6.
Tauranga Boys' captain Connor Fifita got one back courtesy of a jinking run back against the grain, but that provided only slight respite.
The score was 40-13 within minutes - Vaeno galloped away to score his second following huge work from Tosi before Jone Lasaganibau scored another from inside the Rotorua half.
The hosts won the second half 21-7, but that fact flattered them.
The result, and the manner in which it was reached, added another dimension to Central and Eastern Bay of Plenty clubs' threats of leaving the Baywide rugby competition next season.
Rotorua Boys' will play Wesley College next weekend for the right to play Hamilton Boys' High for a place in the country's Top 4.
Rotorua Boys' captain Jessie Williams was thrilled he had not yet played his last game for the school. "I was saying in the sheds before the game that it could have been my last game of the year - it's definitely motivation to keep it going," Williams said.
