His first class debut came during the 2006 Vodacom Cup competition, coming on as a late substitute in the match against the Free State Cheetahs in Bloemfontein.

Despite starting in just six of the Blue Bulls' thirteen matches (and being a substitute in six more), Olivier ended the season with a tally of 76 points, which put him joint-eleventh in the competition.

He was included in the matchday squad for one match during the 2009 Currie Cup Premier Division, against the Bulls in Durban, but failed to make an appearance.

Olivier returned to South Africa in 2013 by joining Wellington-based side Boland Cavaliers for the 2013 Currie Cup First Division competition.

They won both the Assupol Blue Bulls Club Championship vs UJ & the Carlton Cup with the 2nd highest score of all time beating the Dragons 83 - 11.
