The German rider won the lion's share of the $215,000 purse in the MARS Equestrian CSI4* Grand Prix on the grass field.

The grass derby field in Wellington saw 44 international entries compete over Olaf Petersen Jr's course, with the German rider duplicating last year's victory.

Cydello is a new addition to the German rider's string; the pair edged Nicola Philippaerts with Derby de Riverland.
