Gallagher Chiefs Head Coach Clayton McMillan said he was delighted to have Ross re-sign with the Gallagher Chiefs.
"I've had the pleasure of coaching [Aidan] for the last eight years and I can tell you, he has worked incredibly hard for everything he has achieved in the game.
''He will tell you himself he's an absolute battler, but it's the no-nonsense blokes like him that allow others to shine.
''It's why it was a no-brainer to lock him in and he will be a real cornerstone of our relatively young forward pack over the next few seasons."
Ross has put in strong performances for Bay of Plenty during this year's Bunnings Warehouse NPC season with the Steamers, who made it through to the semi-finals.
