Brendon McCullum admitted the controversial dismissal of Ross Taylor cost New Zealand very little as they were beaten by England in the deciding one-day international in Auckland.
Taylor was caught behind off Stuart Broad during the hosts' innings of 185 all out, the victim of a contentious DRS decision when Hot Spot appeared to show no contact.
But McCullum conceded his side was way off the pace at Eden Park and paid tribute to England's impressive bowling attack as the series went the way of the tourists 2-1.
The New Zealand skipper said: "I wondered whether there were fireworks which could have been going off at the same time!
"I would have thought the lack of an edge on 'Hotspot' was conclusive enough evidence. If you nick the ball it shows up on 'Hotspot', and if you don't nick it it doesn't.
"But that wasn't the losing of the game. We were outplayed in many different areas ... it was just a bit frustrating at that point.
"I thought England bowled outstandingly early on. They extracted some pace and bounce at the start that probably wasn't seen for the remainder of the game.
"It put us under that early pressure and to be bowled out for 185 on such a good wicket was never enough.
"It's a missed opportunity. After going 1-0 up in the series, riding on the back of such a good performance in South Africa as well ... clearly it's disappointing in the dressing room."
