In reply, the Knights reached 38-2 before the lunch break but lost Daryl Mitchell for 0 after the restart to be 42-3. It was up to Black Caps Dean Brownlie and BJ Watling to put together a partnership and they combined for 52 before Brownlie was out for 45 off 73 balls.
Mitchell Santner, who had taken 2-25 with his left-arm spinners, joined Watling but the keeper was out soon after, bowled by Michael Bates for 25. That left a few doubts in the Knights' dressing room with the total 103-5. The doubts increased dramatically when Santner was out for 15 and then Hickey fell for 12 at 135-7, leaving 20 more to win with 10 overs left.
A booming six and two fours from Scott Kuggeleijn was just what was needed, then Sodhi was out at 150-8.
Bay of Plenty's Jono Boult crashed a boundary from the first ball he faced and saw the Knights home beside the impressive Kuggeleijn, who was unbeaten on 25.
Aldridge says the Knights are confident they can go all the way in the competition.
"We haven't really put it together as a whole game yet, which has been a frustration for the whole campaign. But that is a positive as well because we know that on our day we can beat anyone."
