An Auckland Rescue Helicopter Trust spokesman said the incident involved a man being struck in the face with a steel beam.

"We were called but due to the hospital being close by we were stood down and the ambulance attended."

The man was taken to Auckland City Hospital in a critical condition, a St John spokeswoman said.

"He is stable," an Auckland District Health Board spokeswoman told the Herald this morning.

The Herald asked the spokeswoman if the man was still serious but she could not comment.
