Canterbury paceman Will O'Rourke has received a maiden test call-up to the Black Caps, but domestic teammate Henry Nicholls has been axed for the South Africa series.

O'Rourke has been added for the second test in Hamilton only, with one squad member to drop out after the first test in Tauranga, starting Sunday week.

Tom Blundell, Kyle Jamieson and former captain Kane Williamson are all expected to be fit, as they make returns from injuries.

Will Young acts as batting cover.
