Martin Guptill struck 71 off 46 deliveries as New Zealand beat Australia by seven wickets on Sunday to seal a 3-2 series win.
The Aussies batted first and managed to post a respectable total of 142-8 in their allotted 20 overs with Matthew Wade top-scoring with 44.
In reply Guptill and fellow opener Devon Conway made a fly start with the bat, putting up a 106-run stand for the opening wicket.
It propelled New Zealand into a commanding position to get over the line with more than four overs remaining in their innings.
