The Hororata plasterer and horse trainer was rescued from the raging Hawkins River after driving into it and climbing out of his car into a tree on May 30.
He was able to phone for help before his phone went dead.
“The car was buggered,” Miller said.
However, he was pleased to find his phone, which had been zipped into his jacket pocket, was still working.
A farm worker retrieved the car and phone, towing the Ranger out from about 100m downstream where it was found on its side, and climbing up the tree to get the phone and jacket.
