The memorable 26-23 victory over Whakarewarewa in the 2014 final is his fondest memory.
"That win really stands out from everything else because that was really quite a few years in the making. We had been building making the semis and made the final a few years but just could never crack it until 2014," Elvin said.
His coach Rodney Voullaire says not too many players reach that 200 game milestone.
"For the Mount he has been a great mentor, leader and is a definite role model. He has stuck at it here even though he has links to Maori clubs like Rangataua and Arataki. Not too many players stay at one club," Voullaire said.
"He has enjoyed every moment of it. He just absolutely loves playing rugby for the Mount."
Elvin is still one of the best loose forwards in the competition and his coach unreservedly rates him highly.
"He is one of the fittest in the team, he is one of the strongest and he can play in any position I put him in. He is a head down, bottom up player and he does the job for you which is exactly what you need out of those senior players," Voullaire said.
"He also has a good senior team leadership around him as well like Zar Lawrence and Sam Mayes who have been with him for a while now."
Mount Maunganui go into tomorrow's round four fixture one of three unbeaten sides along with Tauranga Sports and Whakatane Marist, with Whakarewarewa in sixth place after a win, loss and draw so far.
Tauranga Sports take on Greerton Marist at Tauranga Domain, Te Puke Sports are home to Rotoiti at Murray Salt Stadium, Rangataua play high-flying Whakatane Marist at Rugby Park, Opotiki host Arataki and Te Puna also travel to the Eastern Bay to play Paroa.
