A parking warden is being praised for his "courageous" actions after he helped restrain a man during a "frenzied attack" at Tauranga's ACC offices.
The warden, who wanted to be known only as Peter, was walking past the Grey St offices about 1pm on Wednesday when someone ran out of the building calling for help.
Peter entered the offices and saw an "out-of-control" man allegedly pushing equipment off desks.
An ACC staff member got the man in a headlock and Peter helped restrain his arms, then used his radio to call for police help.
Peter praised the actions of the ACC staff member. An unidentified third person also helped restrain the man until police arrived, by which time other ACC staff had retreated behind locked doors.
