The ladder truck had to be parked on a bridge, temporarily causing a partial road closure.
"Because of the nature of injuries we elected to use a turntable ladder and basket and winched him out," Senior Station Officer Stephen Butler of Christchurch Fire Station said. Mr Butler described the bowl as "like a deep swimming pool."
The injured man was "conscious and quite jovial," he said. "He's a BMX rider, you know what sort of character they are. I can't estimate his age but he wasn't young."
Mr Butler said his fire crew had specifically trained for this sort of rescue. He believed this was the second similar injury in the advanced section of Washington Way in six months.
"There's no design flaw - it's what the experienced guys have asked for."
The man was transported to Christchurch Hospital with Status 2 injuries including possible fractures to leg, hip and arm.
