Auckland ended a disappointing T20 campaign on a winning note at Eden Park yesterday.
They beat bottom side Central Districts by 33 runs. Auckland reached 194 for five, with forties from Colin de Grandhomme and import Chris Nash, and restricted CD to 161 for seven.
Auckland finished fifth on 20 points, while CD didn't win a single game and ended on six points.
Defending champions Otago are through to Saturday's final, where they will meet Northern Districts or Canterbury.
Final points: Otago 26, ND and Canterbury 24, Wellington 20, Auckland 20, CD 6.
