The side, which is fielding a senior men's and women's side, a futsal side and a youth team, announced a new naming sponsor yesterday and also unveiled a playing strip for its four sides.
The side will be sponsored by McDonald's Dunedin for the next two seasons.
Football South chief executive Chris Wright said it was a significant sponsorship from McDonald's and he was excited to announce the new deal.
Wright said the sponsorship was good for two reasons.
''One of the best things about sponsorship is the contribution in financial terms you can give a team and help them along,'' he said.
''It also brings the benefits we can get from the tie-in. McDonald's has 150,00 customers through its doors every month.
''So that gives us a really good reach into the community, who we can tell about the game and what is coming up.''
He declined to say how much the new sponsorship was worth.
McDonald's Dunedin operators Justin and Eterei Stonelake said they were excited to extend the company's community involvement in football with an emphasis on local football.
The new strip was a change to go for more Otago-based colours.
He said it had only been over the weekend that the new colours and strip, from Nike, had emerged and Football South had decided to make the move to this strip.
It had the blue and gold Otago colours and was also a striking layout unlike most other football strips which just had the one colour on the shirt.
Wright said the players had all liked the new strip and it was a change from the all blue of the past few seasons.
Football South had taken over the running of the Southern United side in the national league earlier in the year after it ran into funding issues and there were doubts over whether it would survive.
The Football South women's, men's, youth and futsal teams will all be called Southern United from this season.
Wright said the budget would be set for the season over the next three or four weeks and they did not have to sink any money from Football South into the Southern United side.
It was willing to invest in the Southern United teams anyway as the four teams were seen as part of the pathway for players in the region.
