While the wet weather and extremely muddy conditions might have kept some spectators away, it made conditions even more challenging for competitors.
Mud was flying and tractors were kept busy pulling out stuck vehicles as drivers attempted to negotiate the hazards.
"We like the mud," Oamaru mud-plug enthusiast Tony Campbell said with a big grin.
The event, which attracted 38 vehicles from throughout the South Island, was organised by the Rotary Club of Waitaki.
It was held at Tim Fox's property at Gemmells Crossing, near Reidston.
Mr Campbell, who enjoyed the challenge, the competition and the people involved with mud-plugging, said it was an excellent venue.
Organiser Ralph Burrell was pleased with the turnout and said it would become an annual event.
