His visa was dated to expire on 31/06/2017, while the rest of the squad's was stamped 31/08/2017.
"It was a clerical error from Wellington and there was absolutely no flexibility from the South African border and they said he had to be sent back to the port that he came back from, which was Sydney," Chiefs coach Dave Rennie said at the time.
