The Volts won the New Zealand domestic twenty20 competition to secure a spot in the qualifying tournament.
Otago will play the fourth-placed Indian Premier League team and the Sri Lanka and Pakistan champions. The top two teams progress to the group stage.
Venues and match dates will be confirmed at the conclusion of the IPL. There is a total prize pool of $NZ 6.9 million, so it is a lucrative tournament.

The Volts should be more competitive this year with players such as Brett Lee, James Fuller and Ryan ten Doeschate potentially lining up alongside Brendon and Nathan McCullum, Hamish Rutherford, Ian Butler and Neil Wagner.
