In a six-hitting spectacular, the tourists finished streets ahead with 15 of the 23 struck - many over the uniquely short straight boundaries at this venue. After Eoin Morgan and Luke Wright had powered England to 214 for seven, 12 runs more than they have ever previously made in the shortest format, Broad's career-best four for 24 completed the job.
The England captain reflected afterwards on an impressive collective performance which left him wanting more of the same. Broad said: "It was a really good experience to be out there today - a record batting score for us, and the energy out there in the field was fantastic."
New Zealand's 174 for nine under lights left them losers by 40 runs, and 1-0 down with two matches still to play in Hamilton and Wellington.
Morgan's 46 was England's top score, but their six-hitters just kept coming - and then Wright, Steven Finn (three for 39) and Broad provided the wickets which meant the hosts' run chase was never quite competitive.
Broad continued: "It was really calm, but a lot of buzz out there - and that's what you're looking for. It was pretty much the complete performance from us today. The power we have is hugely exciting. Our challenge now is to make it as good as it was today at Hamilton."
The strange dimensions of the playing surface for this first match lend themselves to an extreme version of cricket. But that said, there was no doubt England adapted far better than their hosts.
"You're not going to see smaller straight boundaries than that. Fielding at mid-off was pretty much long-off," said Broad. "But some of the striking would be sixes anywhere in the world.
"It was probably quite a good toss to lose in the end, because we saw how we batted on it and then communicated really well and defended the smaller boundaries well. We knew we wanted to go into the wicket, take pace off the ball and get the guys hitting to the bigger boundaries - and that really worked for us.
"We made it difficult for the New Zealand batsmen to time the ball and settle into any rhythm. It was just a chip for the spin. We saw Jos Buttler came in, and from ball one pretty much played a back-foot punch for six over long-on."
