Peacock estimated his Hereford bull had been carried up to 80km on the watery trip, which included being swept into the Maruia River, over the 10m-high Maruia Falls, surviving the confluence with the Buller River, going under O'Sullivan's Bridge, and the long twisting journey through the Buller's rocky upper and lower reaches, and then avoiding being swept out to sea at journey's end.
"It's a fairly long trip and amazing he survived. I was quite happy when I got the call he was alive. I think he will get legend status now and be put in a paddock to retire with some cows."
Peacock said the second February flood was worse than expected. One of his neighbours lost 74 cows to the flood.
"The July flood was supposed to be a 1-in-100-year event. This was three to four feet higher. It's the highest I've ever seen on my place. They forecast 60mm and I tipped out over 160mm from the rain gauge the next morning."
However, the fencing, debris and silt damage to the farm was not as bad as that from last July's flood because the river rose and fell more quickly.
The July floodwaters stayed around for 28 to 30 hours, which did more damage and dumped more silt in the paddocks, he said.
"But this one was faster-flowing."
Peacock thanked a group of Murchison residents who travelled out to clear debris off fencelines across his and his two neighbouring farms.
"We are stringing wires now."
