Martin Guptill will miss New Zealand's Twenty20 against South Africa, as well as two one-day internationals versus the Proteas, after suffering yet another hamstring injury.
Hamstring problems have forced Guptill to miss the T20 series with Bangladesh and two ODIs against Australia inside the last two months.
A recurrence of the issue will allow Glenn Phillips to make his international debut against Farhaan Behardien's T20 side, while Dean Brownlie returns to the ODI fold, having made 63 to help the Black Caps secure a series win over Australia.
"Glenn was outstanding for Auckland at the top of the order in the Super Smash and proved an extremely exciting player," said selector Gavin Larsen.
"He bats with power; has shown he can clear the rope, and gets a deserved opportunity to showcase his skills on the international stage.
"Glenn will play as a specialist batsman only, with Luke still taking the gloves. Playing in his home city, it will certainly be a big occasion for Glenn."
Larsen added of Brownlie: "Dean was the logical player to come into the squad following his recent performance against Australia.
"We've seen the quality he brings and we're confident of the job he can do for us."
