Other proposed changes include expanding a revamped Bing Harris Shield from seven to eight teams, and cutting back to four senior teams for a separate competition which would run from December to January.
Dunedin Cricket Association operations manager Andy McLean said it was expected the planned changes would be ratified at the DCA's annual meeting on July 29.
Club feedback at the end of last season revealed dissatisfaction with the bye round in the two-day competition and it was decided to form a working party to address the issue.
The bye caused disruption to the competition and meant some cricketers were spending extended periods off the field.
The report recommended the two-day tournament be replaced by a form of declaration cricket and the Bing Harris Shield be split into two periods, from October to November and February to March.
It also suggested an eighth team be included to avoid a bye round, with a separate competition involving four teams staged from December to January.
While this is a dramatic change to the way senior club cricket has been played, Otago coach Mike Hesson was in favour of the changes.
"I was excited that they were quite forward-thinking to come up with solutions to the unique issues that Dunedin cricket face," Hesson said.
The State Shield-winning coach was not concerned ditching the two-day competition would have a detrimental effect on players' skills.
"The two-day cricket that is played [in Dunedin] is trying to fit four one-day innings into two days, so it is no different from playing two one-day games, really."
The declaration format has not been finalised yet but as a guide the games could be staged over 110 overs, with the team batting first having until the 60th over to declare.
That format would encourage captains to make tactical decision about when to declare and allow teams an opportunity to bat for a draw if the target was out of reach.
"They haven't come up with the format yet . . . but I think it makes an awful lot of sense. It is played in a number of parts of the world quite successfully."
Dunedin club cricket had been strong during October and part of November when the Otago players were available for their clubs and so many students were still in the city.
But from December through to January, the standard of cricket fell away, and cutting the competition back to four teams made sense during that time, Hesson said.
He hoped cutting back to four teams would encourage some competition for places and a more flexible season would help lure senior players back.
The proposed eighth team would be a new team made up of students and two or three Otago contracted players.
Last year's District Series, which involved a team each from Southland, North Otago, Central Otago and Dunedin, would continue.
