Jos Buttler is feeling refreshed after the emotional grind of a Cricket World Cup and Ashes series and revealed he has been working with Marcus Trescothick to improve his red-ball game.
Buttler scored a century in England's drawn tour match against New Zealand A and heads into the Test series against the Black Caps as first-choice wicketkeeper.
The 29-year-old's touch with the bat and neat work with the gloves were among the plusses for England in the three-day contest.
After taking a five-week break to recover from a busy English summer, which resulted in World Cup glory and a drawn Ashes, Buttler is taking an open-minded approach into the two-Test series, for which he has been preparing with former Somerset team-mate and England opener Trescothick.
"I've nothing to lose with the bat or the gloves," Buttler said. "It's a great time to be involved with a new head coach [Chris Silverwood]. It's a new challenge and I'm going to throw myself into it.
"It was a tough summer - physically and emotionally - great fun, a huge challenge and one you look back on with real fondness. But it took a lot out of most of us. The time we have had off has been invaluable.
"I had a couple of net sessions at Somerset with Marcus Trescothick during this time. I really enjoyed that and got a lot out of it. It gave some building blocks to come here feeling in good touch."

England may have fallen short of victory but skipper Joe Root was encouraged by his side's batting in Whangarei.
During the Ashes, England's highest first-innings score was 374 in the lost Edgbaston Test but they posted 405 all out here and Root wants to see his team making big numbers.
"We want to bat long, especially in the first innings - get ourselves into the game and give us an opportunity of making really big scores. Four-hundred-plus, as generally you can dictate terms from there," Root told Sky Sports.
"It is something we have struggled with over the last couple of years, granted that at home, in particular, we have played on some very challenging surfaces.
"On flatter surfaces, like here, I think it's really important that we get into that mindset.
"I think we have done that really well so far in the two games that we have played, with a couple of guys looking in really good order. I feel we are in pretty good shape going into two big Test matches."
