Those tours will introduce new faces such as Canterbury all-rounder Cole McConchie and Wellington paceman Ben Sears, but the most intrigue comes with the early naming of the World Cup squad as the Black Caps gun for a second international prize this year.
The tournament in the United Arab Emirates has demanded a strong spinning roster, with Santner, Ish Sodhi and Todd Astle all selected, as well as part-time options (and destructive hitters) in Mark Chapman and Glenn Phillips.
Jimmy Neesham and Daryl Mitchell are the seam bowling all-rounders, with Colin de Grandhomme omitted, while Martin Guptill, Tim Seifert and Conway are the top-order batsmen, as Finn Allen and Colin Munro miss out.
A familiar fast-bowling quartet of Boult, Southee, Jamieson and Lockie Ferguson have been picked, with Adam Milne unlucky to have only been named as injury cover after strong performances on the worldwide T20 circuit.
Ross Taylor, unwanted for T20 selection, was picked for the three ODIs in Pakistan, but with the brief nature of the one-week series and the length of quarantine, it was decided in conjunction with Stead that Taylor would remain at home to prepare for the Indian test tour in November and December. Wellington all-rounder Michael Bracewell also turned down selection for the Bangladesh T20s and Pakistan ODIs, as he awaits his first child.
Many of the snubbed players will have a chance in prior tours to stake their World Cup claim in case of injury, with the likes of Allen, de Grandhomme, Will Young and the fast-bowling options of Matt Henry, Hamish Bennett and Jacob Duffy all having performed strongly in recent T20s, giving New Zealand Cricket the confidence to go ahead with their bold four-month strategy.
"The need to safeguard the wellbeing of our players and support staff is now very real, and we've endeavoured to do this by carefully managing their workloads over this winter's massive playing programme," said NZC chief executive David White, noting the Players Association was on board with the move.
White also confirmed that the Black Caps involved in the prematurely suspended IPL would be allowed to rejoin their franchises, and complete the competition when it restarts in September.
"It's a pragmatic approach," said White. "We've always tried to be realistic about the IPL and this particular issue is very much a one-off, caused by a unique set of circumstances."
The first Black Caps squad will depart for Bangladesh on August 23 and the players from the test tour to India will return home and emerge from MIQ just before Christmas.
