With a new captain for each side and a plethora of new caps strewn across both squads, South Africa and New Zealand have ground to gain in the T20I rankings.
This month's Twenty20 International series against New Zealand will bring fresh challenges for South Africa, particularly after a change in coach, and skipper - and the induction of four new caps.
An increasingly busy calendar has seen some topflight outfits make modifications at their helm, with the Proteas the latest to follow in the footsteps of a trendsetting England unit.
Russell Domingo has taken the reins from head coach Gary Kirsten for the international game's shortest format, and Faf du Plessis will captain the side in the absence of the rested AB de Villiers.
The uncapped quartet of Aaron Phangiso, Chris Morris, Quinton de Kock, Henry Davids, meanwhile, have been drafted in to compensate for the voids left by de Villiers, Jacques Kallis, Hashim Amla and other seasoned statesmen.
Domingo has pledged at least one game to each, but the makeup of his final XIs remains the balance, with the combination entrusted with the top of the knock particularly intriguing.
The Black Caps, however, have not been afforded such luxury.
An alleged fallout between coach Mike Hesson and Ross Taylor has left Brendon McCullum in charge of the T20I team as well as the ODI and Test XIs - potentially overbearing roles for a player already tasked as limited-overs wicketkeeper.
Injury to Adam Milne, Tim Southee and Mark Gillespie, too, has left the bowling resources depleted, while their Twenty20 ranking (eighth, three berths lower than South Africa) does not bode well.
McCullum, regardless, will hvae to work with the personnel at his disposal. Be they stopgap or long-term prospects, Corey Anderson, Colin Munro and company are in for a veritable of baptism of fire a long, long way away from home.
A three-match affair, in Durban, East London and Port Elizabeth, this series will offer an intriguing precursor to the tour's later fixtures: two Tests, and three ODIs.
Controversially, though, the third and final T20I has replaced the traditional Boxing Day Test, with consequent ticket sales relaying a poor move by Cricket South Africa.
It's all eyes on Quinton de Kock in the home cap. Beating Heino Kuhn, Thami Tsolekile and Dane Vilas to the wicketkeeper-batsman post, the pressure will be heavily squared on the youngster's shoulders.
Number one batsman, wicketkeeper and captain again, Brendon McCullum needs a big series amid a plethora of newbies. Not the cliche it often is, the need to 'lead from the front' is a must on this occasion.
