England captain Ben Stokes allayed fears over his fitness despite an injury scare on Sunday.
Stokes' side claimed an eight-wicket win over New Zealand in Christchurch, with Brydon Carse taking six wickets in the second innings.
But while Carse starred, becoming the first England seamer since Ryan Sidebottom in 2008 to take 10 wickets in an away Test match, Stokes was forced to abandon a bowling spell midway through his fifth over.
However, the England skipper claimed he was merely managing his body, and he is confident of being fit to feature in the second Test, which starts on Friday in Wellington.
He said: "I've not spent that much time out in the middle for a long time.
"It's been a pretty heavy week this week: a lot of time in the field, bowled 20 overs, and then spent some time out in the middle.
"I hurt my back diving for a ball as well.
"It's more management than anything else: with where we were in the game, it didn't feel necessary to eke out any more balls than I needed to. I think the body is going to be good for this outing, and I'm raring to go for Wellington."
Stokes also had special praise for Carse.
"I've been fortunate enough to grow up with Brydon [Carse] in my Durham days and I've always known his potential and his talent," Stokes added.
"So to see him come into this team and make an impact so early on is amazing. He's an absolute workhorse and he'll keep charging in all day regardless of whether conditions are in his favour or not.
"To see him get his rewards, walking off with six-for and 10 in the game is amazing."
It was a humbling defeat for hosts New Zealand, who were left to rue some sloppy fielding. Captain Tom Latham, though, was not too downcast.
He said: "Isolate the first two innings, that sort of surface, the position we were in, I was happy.
"We had our opportunities, on another day the catches go to hand and it would've been slightly different. That’s the sport we play.
"Some days it doesn't fall your way. From our point of view, guys aren't meaning to drop them, they are trying. Some days they catch them, other days it drops, that's the game of cricket."
