Twelve teams, including the Otago Volts, will compete in 23 matches scheduled to be held from October 8 to 23.
Otago qualified for the tournament by winning the New Zealand domestic twenty/20 title.
The Volts will be joined by 2009 Indian Premier League (IPL) winners the Deccan Chargers, losing finalists the Royal Challengers Bangalore, and the Delhi Daredevils, who topped the league following the round-robin phase.
Also confirmed are Australian domestic twenty/20 finalists the Victorian Bushrangers and the New South Wales Blues, Cape Cobras and Diamond Eagles from South Africa, Trinidad and Tobago from West Indies and Wayamba from Sri Lanka.
England's twenty/20 cup finalists will also qualify.
The teams will be divided into four groups of three, with the top two teams in each pool going on to the second stage.
The top four sides will then move on to contest the semifinals.
Meanwhile, Black Caps captain Daniel Vettori has warned New Zealand cricketers may opt to play in the IPL rather than for their country if the twenty/20 competition continues to clash with international commitments.
Vettori was one of six senior players who delayed signing their central contracts until last week after scheduling conflicts between the IPL and New Zealand's international programme next season had been clarified.
"It's a difficult decision and people have families and other issues to work through but our priority was to play for New Zealand," Vettori told the Herald on Sunday newspaper.
"But we realise that if these situations continue to come up it will be difficult for players to continue to turn down the money, so we implore the powers that be to [find a solution] so we don't have to make these decisions every year."
Vettori and several other players arrived late for New Zealand's tour of England last year after playing in the inaugural IPL.
