The victims of crimes that people proved to be crazy say they are treated as second-class citizens.
They demand a change of laws, with a petition launched in Nelson today, seeking the same rights as other victims of violence.
"The victims of people who are excused for a crime because of madness have much less rights than other victims of crime," explains the petitioner Wendy Hamer.
The former psychiatrist was brutally attacked by a patient almost 10 years ago.
He was not convicted of a crime because he was considered crazy by the courts and instead was placed under the care of the health system as a special patient.
Since last month, Mr Hamer discovered the man who tried to kill her was moved to her hometown.
The damage after the attack was equal to attack and the worst thing is that this continues to happen.– Wendy Hamer
"So to me was the last straw," she says.
"At least, we should not expect more damage after a brutal attack I received. But the injury after the attack was like attack, and the worst thing is that this continues to happen. The attack was only 40 minutes in my life."
As a registered victim of a "special patient", Mrs Hamer must be informed of some of his movements.
"I am entitled to know his first uninterrupted leave from the hospital. I am entitled to know when he is AWOL and the right to know when he has a legal change," she says.
But she has no legal say about his relocation or condition of release unless the patient gives consent.
Nelson MP Nick Smith works with her to change it.
"What we are trying to do through Wendy's petition is to balance the law so that there is a constant focus on the fact that there is a victim and that the victim's rights and protection must be taken into consideration," he says.
It also includes the right to make a statement for the victim.
A survivor 1 NEWS spoke to, who can not be named for legal reasons, had to get permission from her attacker to read a statement in court.
"It was just horrendous to me," she says.
She says that her perpetrator was entitled to her personal records, but she has not been allowed to him.
"To remind me that my consent and my will were irrelevant, that I was powerless and helpless, just days after being raped, served as a traumatic and parallel experience for me," she says.
In a reply from the Justice Department, a spokesman said a statement about victims was made to help a court judge a perpetrator.
"As people who are not guilty due to mental illness are not judged but can be treated instead, there is no right that a statement about the victim's consequences be read to the court," says Tania Ott, senior police officer.
"However, this does not prevent judges receiving the victims' statements in their consideration."
It says that a number of services are available to help all victims through the judiciary. And the Ministry of Health says that all its special patients are carefully monitored.
"Wendy's Petition" will be presented to Parliament by Dr Smith next March.
