The grounds outside Parliament have become a crime scene this evening after a man set himself on fire.
The man was in a critical condition after apparently setting himself alight outside the Parliament buildings just before 3.50pm.
Paramedics treated the man at the scene and he was taken to Wellington Hospital, where a spokeswoman confirmed about 6.20pm that he was still critical.
Newstalk ZB political editor Barry Soper said the man was a regular protester at Parliament and was well-known to security.
Extra security staff had recently been hired for Parliament, he said, but there was nothing to stop anybody coming onto the building's forecourt.
Wellingtonian Matt Weldon-Smith said over the last two days when he left work in the late afternoon he had seen the man protesting outside the Court of Appeal on the corner of Molesworth St.
"He hasn't been ranting or raving or anything - just silently holding a sign there."
He believed the sign was the same one that was visible on Parliament's forecourt this afternoon.
"I read the sign, it doesn't really make a lot of sense to be honest. Obviously he had some sort of problem with the Family Court situation there but I couldn't make head or tail of the sign."
Weldon-Smith said earlier in the week the man had also carried a sign saying that in Iraq or Iran "they stone women, in NZ they stone men".
He said the man appeared European and aged in his 50s or 60s.
Police have confirmed a man is critical after setting himself on fire, currently receiving medical treatment. No information on why.
Access restrictions around Parliament are in place and people have been advised to exit via the back of the building.
MPs and parliamentary staff were still being allowed into the building but members of the public were not.
"When leaving the precinct you will need to exit to the rear of the buildings," said a notice from Parliamentary Services. People with cars in the underground carpark will need to exit via Museum Street."
