Big-hitting Blackcap Colin Munro will no longer seek selection for Test or four-day Plunket Shield cricket.
The 30-year-old, one of the finest Twenty20 batsmen in the world, has played just the single Test for New Zealand, against South Africa in early 2013.
But he has played 39 ODIs and 45 T20 internationals.
Munro said on Friday that he'd focus on white-ball cricket from now on, both with the Blackcaps and the Auckland Aces.
"I'm still 100 per cent committed to playing for the Blackcaps and Auckland Aces in the shorter formats and have some big goals I'd like to achieve," Munro said.
"Obviously with the World Cup next year, I'd love to give myself the best chance of making that squad and that's where my main focus is."
As such, the Durban-born Munro will sit out the New Zealand XI's upcoming pair of two-day warm-up matches against England in Hamilton.
Taking place back to back, Martin Guptill will captain a red-ball side on March 14 and 15 before Tom Latham takes the reins for a pink-ball side on March 16 and 17.
The Caps' first of two Tests against England will follow the week after.
"There's a number of our front-line guys in there and this is a great opportunity for them to get ready for what is a huge Test series," selector Gavin Larsen said.
"We've also selected a very strong group of fringe players around our current Test group and this is a fantastic opportunity for them to challenge themselves against a very good international side."
Stalwart Ross Taylor has been named in the red-ball side despite aggravating a thigh issue in Wednesday's fourth-ODI win over England.
There is some overlap between the two sides, with Tom Blundell, Scott Kuggeleijn, Seth Rance, Ish Sodhi and George Worker to play on all four days.
