He said in more recent years they had held matches at Tauranga's Baypark Stadium but the players and coaching staff had voiced concerns about the playing surface and facilities at the stadium.
He said that was one of the factors in bringing a game to Rotorua this year.
"We have made no secret of the fact that the playing group and coaching staff are not that keen on Baypark," he said.
"They have always enjoyed playing in Rotorua ... and we felt it was time to get back there."
Flexman said changes to the Super Rugby season from 2016 onwards, and the addition of Taranaki to the Chiefs region, made bringing games to the regions more difficult.
However, he said it was not out of the question for Rotorua to be part of a regular cycle, with games held in the city every three years for example.
The Chiefs' last game in Rotorua was a pre-season match last year against the Blues.
