The death comes just days after four-year-old Maggie Watson died in unexplained circumstances in the Auckland suburb of Onehunga.
Police are revealing few details in both of these cases.
So far this year, five children under five have been killed in suspicious circumstances - so how do we ensure our young and vulnerable are actually safe in their own homes?
Child Matters chief executive Anthea Simcock joined Paul Henry this morning to discuss why there are so many tragic deaths like Moko's.
"In a nutshell, it's because we tolerate it and we often say 'What's the Government going to do [and] who should we blame?'," says Ms Simcock. "But until we as a nation stand up and say that 'It's not the Government's fault, it's our responsibility – what else can we do?' I doubt that we will get on top of it."
