Rogers said the many changes over the years included the high-tech facilities, especially coaching, television reviews and the catering.
"They are just a professional outfit now. They're 100 per cent more professional.
"These guys, I think, are alot more aware of who they are playing for and against."
He said they did not have the likes of School Challenge, Top Four and World Championships in 1988.
Rogers said the school had also embraced Māori culture.
Players have returned to Rotorua Boys' High School from all over, including England, Perth, Sydney and Brisbane.
"It was nice coming back to the school and catching up with the guys."
Current Rotorua Boys' High School first XV captain Tuki Simpkins, 16, said it felt special and amazing to have the 1988 team there for its reunion.
"They still have this close bond. We have this special bond, and hopefully we can catch up 30 years down the track as well. It's really cool."
