John McGlashan College beat South Otago High School 22-17 on Saturday to win the competition, which replaced the defunct Highlanders First XV competition.
The secondary schools council will review and decide the future of the competition on September 11, but Munro said he had so far received only good feedback.
''Certainly our sponsors are delighted with what's happened,'' he said.
''I think there's a very positive feel for what's happened this year. Less travel has been very popular both financially and from a time-consuming point of view.''
Teams were also spared an entry fee this year, which cost each team $3500 in the old Highlanders competition.
With teams not required to travel to Southland for games, travel costs, which were subsidised by sponsors, were significantly reduced.
Munro said if there was one thing he would like to see change in the competition it would be the introduction of semifinals.
''I think there will be some tweaks,'' he said.
''We did feel that the two teams that played the final were quite predictable some time out and that possibly took away a bit of excitement or motivation from the other teams.
''The 10-team format followed by a top six seemed to work well. The more elite teams had some very close competition and it did give other sides a good opportunity to have a crack at the bigger teams.''
Munro also pointed out that the number of blowout wins had been reduced this year with Otago Boys' First XV opting to play in the Dunedin premier colts grade.
Southland secondary schools representatives have approached Munro to express an interest in relaunching some sort of combined competition, but Munro said ''I can't see us rushing back to it''.
Cross-over matches between Otago and Southland schools at the end of their respective competitions was one idea that had been floated.
But fitting it into an already busy calendar would be a challenge, especially when teams are busy playing off for spots in the open and co-ed South Island sections at the end of their respective competitions.
John McGlashan team director Mike Idour said he was keen for the competition to stay within Otago.
''I know some of the Southland schools much preferred not coming up here to get slaughtered. Less travel has got to be a good thing,'' he said.
Idour felt the competition was ''probably two teams too big'', but was not sure how fair it would be to exclude two teams.
Kavanagh College coach Damon Sutherland said he liked the structure of the competition and felt it had helped his school develop its players.
After struggling at the start of the competition and getting relegated into the bottom six, Kavanagh won all of its games down the stretch to finish seventh.
He suggested the introduction of playoffs, including one between the sixth and seventh teams.
The cost of reverting to an Otago-Southland competition would be ''horrendous'' and Kavanagh had still spent between $4000 and $5000 on travel for three games outside of Dunedin, Sutherland said.
South Otago coach Adam Whaanga does not want the competition to include Southland teams and thinks it will go from strength to strength if it is retained in its current form.
• Fullback Rory van Vugt scored four tries in South Otago's 60-14 win against St Kevin's in their co-ed playoff match in Balclutha yesterday.
South Otago will play Kavanagh College, which beat Dunstan High School 46-42 in Dunedin yesterday, in Balclutha on Saturday.
The overall South Island champion will play in the top-four schools competition in Rotorua next month.
