His mother left him in a friend's care while she tended to a sick sibling in hospital. Two months later, that friend called an ambulance and lied about how he'd been hurt.
Moko Sayviah Rangitoheriri, 3, died in Taupō, New Zealand, on August 10, 2015, after sustained abuse by his caregivers. The case caused national outrage and led to New Zealand's longest-ever manslaughter sentence for the killing of a child.
Left in a Friend's Care
Moko's mother, Nicola Dally-Paki, left him and his older sister in the care of Tania Shailer, a former kohanga reo (early childhood) teacher who had cared for her children before, while she traveled to Auckland to be with another sick child at Starship Hospital. Shailer's partner, David Haerewa, later joined the household as well.
Sustained Abuse
Over roughly two months, Moko was subjected to escalating abuse by Shailer and, later, both Shailer and Haerewa together. Given his age, we won't detail the full extent of what he endured, beyond confirming it was severe, sustained, and ultimately fatal, involving repeated physical assaults and a denial of medical care.
A False Story, and a Death
On August 10, 2015, Shailer called an ambulance, telling paramedics Moko had fallen from a wood pile. When he arrived at Taupō Hospital, medical staff found him with severe facial swelling so extensive his eyes couldn't be opened for examination, extensive bruising, and a bowel injury that had caused a life-threatening infection. He died that evening. A post-mortem determined the cause of death was multiple blunt-force trauma.
Charges Reduced to Manslaughter
Shailer and Haerewa were initially charged with murder. Prosecutors ultimately accepted guilty pleas to manslaughter instead, citing evidentiary uncertainty about whether murderous intent could be proven beyond reasonable doubt at trial, and noting Moko's injuries, while severe, weren't necessarily fatal without the failure to seek timely medical care. New Zealand's Attorney-General later defended the decision publicly, saying it secured convictions while avoiding the risk that either defendant could have escaped conviction entirely at trial.
Sentencing
In June 2016, both Shailer and Haerewa were sentenced to 17 years in prison with a minimum non-parole period of nine years — the longest sentence ever imposed in New Zealand for the manslaughter of a child. Court documents later revealed the pair had more than 100 prior convictions between them.
A Rejected Appeal
Both killers appealed their sentences, with Shailer's defense arguing her documented mental health conditions had diminished her culpability. New Zealand's Court of Appeal rejected the appeals in March 2017, with the presiding judge stating the case's cruelty placed it among the most serious to which a starting point of life imprisonment could apply, and that the pair "can count themselves fortunate" not to have received life sentences.
A Lasting Public Response
Moko's death prompted nationwide protests and a petition to Parliament calling for an end to plea bargaining in cases of severe child abuse. His mother has continued to advocate publicly for stronger child protection measures in the years since.
Frequently Asked Questions
Are Moko's killers still in prison?
As of the most recent public reporting, both remained incarcerated under sentences with a minimum non-parole period of nine years, following their unsuccessful 2017 appeal.
Why were they convicted of manslaughter rather than murder?
Prosecutors accepted manslaughter pleas due to evidentiary uncertainty about proving murderous intent beyond reasonable doubt, a decision New Zealand's Attorney-General publicly defended as still reflecting the seriousness of the crime.
Did this case lead to any changes in New Zealand?
It prompted widespread public protests and a parliamentary petition against plea bargaining in severe child abuse cases, and remains frequently cited in New Zealand child protection policy discussions.
