The experienced Ross Taylor averages a strong 45.59 in tests and his return will shore up the gap left by McCullum and help captain-elect Kane Williamson.
However one of the opening roles and the choices at five-Nicholl, Corey Anderson, Mitchell Santner, Neesham, Colin Munro-do not have anything like that look.
Ryder could be used in either role.
He plays and leaves the new ball well and has a range of strokes to combat the pace-laden South African attack and can also adapt to the batting detail if he is put in the middle order.
This time it seems there has been no coercion. Ryder has made peace with himself and asked about his chances and that inquiry has piqued the selectors' interest.
So it should. Ryder averages nearly 41 in his 18 tests and 33 in almost 50 ODIs and that's gold for a flimsy NZ test batting lineup.
