A man found guilty of killing Christchurch woman Renee Duckmanton has had his appeal against his conviction dismissed.
In April, Sainey Marong was sentenced to life in prison for a minimum of 18 years for murdering Ms Duckmanton in 2016.
But Marong argued in the Court of Appeal that the jury's verdict was wrong and that they should have found him to be insane.
In a judgment issued today, the court said the question of whether Marong was insane was for the jury to answer.
It said expert trial evidence about his state of mind was unequivocal that he did not suffer from a disease of the mind, and was able to understand what he was doing.
