They asked him to move on, saying he was distracting drivers.
A bus driver complained to police about his unusual advertising site, and police paid him a visit to warn him to stay off the roundabout.
"I'm showing initiative but they nearly arrested me for distracting drivers with my sign," Mr Langley said.
The stonemason and tiler arrived from Australia nearly two weeks ago to work in Queenstown and go climbing in the area but had been unable to find work.
"The cops said 'don't you have a resume', but I've tried that. Now I just want to put myself out there. I've been on every building site in Queenstown, but there's not that much work going," he said.
He was willing to do "anything" and just wanted to earn enough to survive and climb.
The keen rock-climber said he came to Queenstown for its stunning mountains.
Constable Hugh O'Reilly said police received several complaints about Mr Langley's unusual advertising site.
"He's trying to find an original way of putting his name out there but it's part of the road. It's dangerous for him and a distraction to traffic," he said.
