NZ-born star called up by Ireland
Aki has recently become eligible for Ireland after completing his three years of residence.
The centre has been with Connacht since 2014 after heading to Ireland from Super Rugby outfit the Chiefs.
Ireland will face South Africa, Fiji, and Argentina in November.
Ireland face the Springboks for the first time since the 2016 tour where Ireland recorded a first-ever victory on South African soil at Newlands but ultimately lost the series decider.
Earlier this month the Boks came within a point of beating the All Blacks in their final game of this year's Rugby Championship having twice drawn with Australia and recorded victories home and away against the Pumas.
The Bok squad will be led by the 63-time capped lock Eben Etzebeth with their full European tour travelling party set to be named after the Currie Cup Final.
"In what we anticipate will be an incredibly physical Series plenty will be demanded of the squad," said Schmidt.
"We have retained a core of experienced players but have also included a number of promising players that we hope will acquit themselves well."
