Jason Collett has ridden a double to finish fourth in the International Jockeys Challenge in Mauritius.

The Sydney-based New Zealander represented his homeland in the series held over the two days of the weekend.

Three-time Singapore champion, Brazilian Manoel Nunes who now calls Mauritius home, rode three winners on Sunday to take the title from Jason Watson (England) and Nooresh Juglall (Mauritius).

Glen Boss had been scheduled to represent Australia until suspension intervened and his place was taken by Singapore-based Australian John Powell who finished 10th of the 14 riders.
