The order was handed down to reduce her original sentence by 11 months, but to keep the initial ruling of her being remanded to a hospital for the duration of her sentence.
Evidence was given that the woman and a male friend went to the victim's home and kicked his door down one evening last year.
Following the break in and while the elderly man was on the phone to police, the woman punched him in the face. After he fell, her co-accused then struck the man on his head four times.
As the man lay bleeding, the woman placed a rope around his neck and started to strangle him. He narrowly avoided death when the woman released the noose and left his home. Palmerston North police arrived on the scene soon after, and found the man slumped bleeding on the floor, still with the noose around his neck.
According to a psychiatrist's report, the woman was suffering from delusions.
