A Taranaki man who killed his 71-year-old mother will have to spend 16 years in jail before he's eligible for parole.
David Blake was today sentenced to life imprisonment, at the High Court in New Plymouth.
Gwendoline Blake was found dead in her Stratford home in January after police were called when neighbours heard shouting.
Her 47-year-old son pleaded guilty to her murder in April, despite saying he had no memory of the incident.
