Stuart Broad was in a buoyant mood after leading England to Twenty20 series victory in New Zealand.
England crushed the hosts by 10 wickets in the final match in Wellington, backing up a fine bowling effort - Broad took 3-15 - with some sublime hitting from Alex Hales and Michael Lumb.
The opening pair needed only 12.4 overs to reach their 140-run target and secure the series 2-1, England rebounding from their disappointment in Hamilton in fine style.
"I can't remember a much more powerful performance from an England side," said Twenty20 captain Broad.
"It was key for us to reclaim some confidence here. We bowled well and held our lengths early and the way we chased down those runs was pretty spectacular.
"There was no panic button pressed (after the second match). We had a bad day but that can happen in sport.
"We worked on the areas we thought needed improving and today we came and put it right. We were on song today."
England now turn their attentions to the one-day series, which begins in Hamilton on Sunday, and Broad added: "We came here to win all the series and this is a great start for us.
"It's a quick turnaround but I'm sure we'll be fully switched on for that. We want to win all three series and we've ticked one of them off."
Hales, who hit four sixes in his unbeaten 80, said: "I thought our bowlers were outstanding from the start. They never let them get away from us and made the batsmen's job very easy.
"I'm happy I managed to contribute. In Twenty20, once you get away you can get into a stride and if you back yourself you can really take a bowler down."
