A Greymouth man who killed his 15-month-old son can now be named.

32-year-old Dane Blake killed his 15-month-old son Leith Hutchinson when he wouldn't stop crying in 2015.

During sentencing in March Blake's lawyer Marcus Zintl told the court Blake was overwhelmed and ill-equipped to deal with a crying child who would not settle.

Blake who was sentenced to five-years and six months for the manslaughter of son - had six months added to his sentence, for three separate drug charges today.
