The New Zealand placings were: Teresa Birkett 3rd, Kylie Avery 5th, Linda Pullar 7th and Lois Hosking 9th.
Struan Duncan qualified in the 80km ride and has since gone on to compete at a 92km ride in Cape Town, where he also qualified.
In Christiana, eight nations were represented at the ride.
Competitors report that the ride was a surreal experience, riding amongst galloping herds of zebra, waterbuck, wildebeast, inpala and springbok as well as rhino, giraffe, ostrich, monkeys, mongoose and more. "It has certainly been a trip of a lifetime for all involved. The South African Endurance community hosted us all very well and we have all made some special friendships along the way," a spokesman said.
Earlier, New Zealander Sandie MacLean placed second on Sanniesgun Sadan in the Open 80km ride at the South African Freestate Championships on May 25. She also completed on Sadan the day before in a stepladder ride over 80km.
