Australia retained the same side that defeated hosts India in the last league match here on Sunday.
New Zealand will miss all-rounder Scott Styris due to a back injury, but pace spearhead Shane Bond was declared fit to play after a hamstring scare.
The second semi-final between South Africa and the West Indies will be played in Jaipur on Thursday.
Kyle Mills strikes early for Kiwis: Kiwis swing bowler Kyle Mills delivered early blows for Aussies by claiming Shane Watson (0) and Adam Gilchrist (3) to leave them reeling on 4/2 in third over.
Mills lured Watson to pull with a shot delivery only to be holed out to Fulton at mid-off, while struggling Gilchrist played a poor shot to be caught at mid-wicket by Jacob Oram. Aussie skipper Ricky Ponting (1) and in-form Damien Martyn (0) were at the crease trying to dole out their team from the early setbacks.
