The two side panels also show signs of an attempt to smash them in - with two holes now showing on the bottom half of each panel.
The defendant was arrested 10 minutes later.
The 31-year-old's case was called in the Wellington District Court this morning, but his attendance was excused. No pleas were entered today.
The man is listed as living in Auckland and is charged with resisting police, intentional damage with reckless disregard to parliamentary property, and possessing an offensive weapon in public.
He also faces an unrelated charge of intentionally damaging a glass wall of a Rotorua petrol station in early December.
He first appeared in court the same day as the alleged offending, but the hearing was held in a secure basement courtroom without media present.
The unusual move was made due to perceived security issues relating to the man's mental state at the time.
Media are entitled to attend any court hearing in New Zealand except in cases where national security is at stake.
On that occasion, however, the secure courtroom was considered not to be large enough to allow media in.
Following that appearance, the man was bailed to a secure facility.
During today's hearing, Judge Bruce Davidson granted a request to continue interim name suppression and noted from the material already before the court there could be an "arguable" case raised for permanent suppression.
The man will next appear for a case review hearing in March.
