The horrific death of a Taupo toddler at the hands of his carers has prompted questions around parents leaving children in someone else's care.
Outspoken children's rights advocate Merepeka Raukawa-Tait has described the death of 3-year-old Moko Rangitoheriri as "another tragic but avoidable children's death".
"Sadly, if nothing changes, there is another little child waiting their turn in the wings."
Moko was abused over a two-month period in Taupo after his mother left him with a couple while she was in Auckland looking after another child in Starship Hospital.
Tania Shailer, 26, and David William Haerewa, 43, pleaded guilty to manslaughter charges on Monday in the High Court at Rotorua on what was supposed to be the first day of their murder trial. The pair tortured the child by kicking him, stomping on him and slapping him. They rubbed his own faeces in his face. He was eventually beaten to the point where he suffered facial swelling, internal bleeding, septic shock from his leaking bowel and swelling of the brain.
