A settlement is imminent between the sole survivor of the Mt Wellington-Panmure RSA killings and the Department of Corrections.
Susan Couch was almost beaten to death by William Bell during the attack on 8 December 2001. He is serving a prison term of 33 years without parole for the murders of William Absolum, Mary Hobson and Wayne Johnson.
Ms Couch is suing Corrections for $500,000 because Bell was on parole at the time that she was injured.
Corrections says it has been in discussions with Ms Couch and her lawyers to settle years of legal action against it.
The department was first taken to court in 2003 by Tai Hobson over his wife's death, but his claim for compensation was thrown out and Ms Couch picked up the case.
Corrections says it expects a settlement by Thursday evening.
