Kamo High's defence stayed resolute as Boys' High failed to cross the line in the second half, even after wide passes by the hosts found their flying winger Matthew Harrison.
A penalty goal mid-second half extended the Boys' High scoreline to a converted try difference, and both sides continued to battle before Kamo scored and captain James Witehira converted to level the score.
Intensity escalated as the clock was running down, and mistakes saw the ball change hands at critical times with no further points scored - the match finishing in an 18-all draw.
