Ben Stokes warned England's Test fortunes will not change overnight after starting the Brendon McCullum era with victory over New Zealand.

Captain Stokes and coach McCullum were tasked with transforming England in the five-day game, and got off to a great start with a five-wicket victory over New Zealand in the first Test of a three-match series.

England were largely indebted to the heroics of former captain Joe Root, who became only the second Englishman to score 10,000 runs in the longest format with an unbeaten fourth-innings 115.

Root is the 14th batter to achieve the 10,000-run tally in Test cricket after England knocked off 277 in the chase on Sunday, recovering from 69-4 on Saturday to fight back against the Black Caps.

The second Test starts on Friday at Trent Bridge and Stokes attempted to temper expectations as he suggested instant success will not be achieved.

"I was always looking to be positive and just really staying true to what I was saying and how I want to captain and not letting the game dictate what I did," Stokes told reporters.

"I was just making sure that I still stuck to my guns in the way that I wanted the bowlers to bowl, the fields that I set, stick to everything that you've been talking about because you know actions speak louder than words.

"It's a great start, we've won, there's obviously going to be you know, ups and downs.

"And it's just about dealing with that but I think having me and Brendon in charge, it's going to be really important how we operate when things don't go well.

"It's not an overnight thing. This is what me and Brendon are trying to work towards and we know that."

Stokes also heaped praise on the attitude of McCullum, who was intent on sending Stuart Broad ahead of debutant Matthew Potts to bat should England have lost another wicket on the evening of day three.

"When Foakesy went out to bat, he was going to send Broady in if we lost the wicket to go and have a slog, just to score 30, 40 runs, then the game's done," Stokes said.

"That's the kind of stuff that we're not used to in the dressing room. Those kinds of things filtering around will do us the world of good.

"The confidence and the energy that he brings about, his mindset towards the game, he's just going to make everybody feel 10-foot tall in any situation and I've really enjoyed working with him so far this week."
