Otago Boys' High School won the competition on Saturday, beating Waitaki Boys' High School 41-3 in the final. It was the second year in a row Otago Boys' had won the final. The competition is in its fourth year.
Highlanders First XV competition committee chairman Des Smith said a full review of the competition would take place in the coming weeks.
He said all schools competing in the 12-team competition fully supported it and wanted it to continue.
But there were issues which needed to be looked at to make the competition work and also make it sustainable from a financial point of view.
Smith said something had to be done about reducing the cost. It cost $85,000 to run the competition and most of that was spent on transport.
It was not sustainable if it continued to run at that cost.
The competition had nearly fallen over at the start of the season, following the Otago Rugby Football Union's financial trouble.
Fulton Hogan had become a naming sponsor this season and Smith said it would continue next year, which was great news.
Bus transport was the main expense and players could spend a lot of time in a bus.
When Invercargill teams played games in Oamaru, and vice versa, some players could spend up to eight hours travelling, which was not ideal.
Smith said there were also suggestions something needed to be done about avoiding scoring blowouts in some games.
Otago Boys' had scored more than 100 points in a couple of games and other teams had also recorded lopsided victories.
Smith said that big scores were inevitable but it would be better to have more even games.
He wanted to make sure every secondary school rugby player in the Highlanders region who wanted to and had the ability to, could play in the competition.
At the moment, pupils attending Mt Aspiring College or Wakatipu High School could not play in the competition as there was no team representing the Queenstown-Lakes district.
He hoped to get some feedback from schools in the next few weeks, before discussing the competition with school principals at the start of the fourth term.
James Hargest College, which finished bottom of the competition, will play Verdon College in a promotion-relegation game this Saturday.
Gore High School will take on St Andrew's College, of Christchurch, in Gore on Saturday, in the co-educational school South Island final.
