It most certainly a day of two halves for the Kiwis though. Emily Cammock and Dambala rode a brilliant clear round with 11.2 time faults, that saw them move from 38th to 18th after the cross country.
However, she has to withdraw him from tomorrow's all-important showjumping phase.
"After the second to last fence I felt something wasn't quite right and as we pulled up at the end of the course it was obvious we had a problem," said Cammock via a FaceBook message.
"It appears that the deep ground has proven too much for an old suspensory injury and he has had to be withdrawn. With plenty of drugs on board he is feeling OK, but we are all feeling pretty sombre."
The conditions had been challenging for the Gisborne-bred grey, but Cammock said he had stepped up and given her a fantastic round.
"He slipped badly on take off at the second fence and I saw the ground approaching rapidly. Luckily he regained his balance and the saddle tight glue kept me on board. After that, the course was a pleasure to ride."
Of the 71 starters, here were just six combinations clear and inside the optimum time, with 26 going clear but picking up time faults, 15 eliminated and 10 retired on course.
Price and Jung are both in the leading Dubarry of Ireland Nations Team Challenge, in a composite New Zealand, Germany, Ireland and Australian team.
