Jonathan Paget and Clifton Lush, who were lying in second spot going into the final phase, parted company during the cross country, eliminating them from the event.
Mark Todd, who was in third overnight was also eliminated after he and NZB Campino missed a fence in the final stages of the cross country course.
However, there was another Kiwi star in another class at Barbury today. Tim Price rode Vortex to a lovely win in the retraining of racehorse's championship, with Dan Jocelyn and Valemont third.
"The win is great for Vortex," said Price. "He is a bit of an old campaigner now, and it's good to be out with him as we have missed a couple of competitions this year due to the rain."
