Rena Maloney appeared in the High Court at Christchurch this morning charged with killing Martin Orme Berry in December last year.
It’s understood the pair were a couple, and Berry's body was found buried in the backyard on Main North Road in Papanui.
Her lawyer Richard Peters entered a not guilty plea on her behalf.
Two months ago, Peters had asked for a mental health assessment to determine whether Maloney is fit for trial.
Today, Justice Cameron Mander said two health assessments have confirmed the 55-year-old’s fitness to stand trial.
Maloney has been remanded in custody.
Her trial date is set down for March next year.
