He is the fourth referee to reach this milestone in the last 20 years.
Ray Coombs, Stephen Wood and Neal Wallace are the others.
"There aren't many, are there?" Rodgers told the Otago Daily Times. "That has surprised me.
"I thought about reaching 100 games last year and I was happy to get there."
Rodgers reached the milestone at the University Oval last Saturday when Southern beat University A 10-6 to lift the prestigious Cavanagh Trophy.
He has no intention of continuing on to reach 200 games.
"I have had some niggling leg injuries and am not sure if I'll be back next year," Rodgers said. "I'll wait until summer to see if the injuries come right."
Rodgers (42), the head of mathematics and mechanical engineering at the Otago Polytechnic, controlled his first full premier game in 2001.
It was between Alhambra-Union and University B at Tahuna Park.
"I was very nervous before the game, but it went pretty well," he recalled.
Rodgers had his first taste of refereeing premier rugby a year earlier when he came on as a replacement at Carisbrook when referee Terry Walsh broke a bone in his foot.
"I was the touch judge in the game between Pirates and Green Island and Neal Wallace told me to take control."
The highlight of Rodgers' years with the whistle was to control the final at Carisbrook in 2005 when Dunedin beat University A 19-12.
"It was my first final and was a big occasion for me," Rodgers said. "It was an enjoyable game to referee with both teams playing positive rugby."
Rodgers was a prop in the Kaikorai Valley High School First XV in 1983 and played senior B rugby for Alhambra and Green Island for 10 years.
He became a referee in 1997.
"I'd finished playing and it felt like a good thing to do," he said.
Rodgers, Otago's top-ranked referee for the last four years, took a stand for abused referees two years ago when he temporarily pulled the plug after a difficult club game between Harbour and University A.
Rodgers resigned after receiving abuse from Harbour supporters during the premier match against University A at Watson Park.
But he came back to refereeing later that year when the Metropolitan Committee took a strong stand against clubs and spectators who abused referees.
The highest level he reached as a referee was to control the game between Otago and North Otago in 2005.
Rodgers had advice for the beginner referee.
"Control things you can like your own fitness and knowledge of the laws," he said. "You learn everything else by experience."
Rodgers is married to Julie (nee Moore) and the couple have three teenage children.
