More calls for Oranga Tamariki to be shaken up following new details about a toddler that was killed in Lower Hutt.  

A homicide investigation has been launched into the death of almost two-year-old Ruthless-Empire Wall.

Newstalk ZB understands his uncle contacted Oranga Tamariki wanting the child to be uplifted.

It comes after it was recently revealed 57 children have died since the agency was established. 

Child Matters Chief Executive Jane Searle told Kate Hawkesby that it reflects the need for change. 

She says they've known for a long time Oranga Tamariki's not fit for purpose, with this being just another example.
