East Coast Bays, champions in 2008, will face three-time winners Miramar Rangers in Wellington while Bay Olympic will trek to Dunedin to take on Caversham on the weekend of August 14 and 15.
The draw, made live on Radio Sport on Tuesday, also opened up the possibility of a Chatham Cup final hosted in Wellington or Dunedin.
New Zealand Football confirmed that if the winter football showpiece, played on the first weekend in September, featured no Auckland team the game would be played at the ground of one of the finalists rather than North Harbour Stadium, the host of nine of the last 11 finals.

Bay Olympic coach Shane Knowles acknowledged a Caversham side in hot cup form and within striking distance of a Football South Premier League title would be a big challenge for his team.
But he thinks the chance of making a Chatham Cup final should be ample motivation for his troops.
“They will be pretty tough down there, there’s no doubt about it. But you’ve got to beat the top teams to win the cup,” he says.
“The Chatham Cup is special and it’s a high priority for us. All the players look forward to it and from a winter football point of view there’s nothing bigger than winning the Chatham Cup.”
