THE reserve grade Tigers played Taree City on Sunday in Port Macquarie, with the loser finished for 2013.
Both teams had chances in the first half, but poor options or dropped ball cost chances.
Five minutes from half time, Brenden Summefield was sent to the sin-bin for holding down a player.
It took until the second minute of the second half for any points to go on the scoreboard, when Joel Kleindeinst scored in the corner.
Just minutes later, he barged over for his second try to lead 8-0.
Taree City scored a soft try to reduce the margin to 8-6 after a quarter of an hour.
Ten minutes from full time, Garyn Burns scored in the corner to make it 12-6.
Both teams had chances to score, but the Tigers held on to progress to the minor semi-final against Old Bar Beach at Tuncurry next Saturday.
Wingham District 12 defeated Taree City 6 (Joel Kleindeinst 2, Garyn Burns tries).
