The death of three-month-old Ronin Stanley-Hunt has exposed a disturbing intersection between New Zealand’s methamphetamine problem, infant vulnerability and the ability of health and social services to intervene before tragedy occurs. His death followed that of his four-month-old sister two years earlier, with methamphetamine detected in both children
Elocal by Report
Ronin John Tony Stanley-Hunt was found unresponsive at his West Auckland home on 18 June 2024. He was three months old.
The formal cause of death remains "unascertained", an important distinction in understanding the case. Coroner Alison Mills did not determine that methamphetamine alone killed Ronin.
Instead, her findings identified a combination of factors likely contributing to his death: methamphetamine exposure, respiratory syncytial virus (RSV), dehydration and an unsafe sleeping environment.
Blood taken during Ronin's post-mortem examination contained methamphetamine at a concentration the coroner said was consistent with exposure through breast milk following recreational use of the drug.
Cotinine, a substance produced when the body processes nicotine, was also detected.
Ronin had tested positive for RSV, and there was evidence of dehydration. The pathologist was also unable to exclude the possibility that asphyxia associated with bed-sharing contributed to his death.
The result is therefore not a simple case of establishing one cause. It is a case in which several identifiable risks converged around a particularly vulnerable infant.
Two Children, Two Methamphetamine Exposures
What makes the case especially troubling is what happened two years earlier.
Ronin's four-month-old sister, Tiana, was found unresponsive in April 2022 in a bed she shared with her mother and another sibling.
Her death was also recorded as unascertained.
Toxicology nevertheless detected methamphetamine in Tiana's blood, with exposure most likely occurring through breast milk.
Two babies in the same family therefore died two years apart with methamphetamine detected in their bodies.
During the pregnancy with Ronin, the family's midwife was told the parents were smoking cigarettes and vaping. After his birth, safe-sleep recommendations were discussed.
When the midwife became concerned those recommendations were not being followed, she offered to help set up a sensor mattress. Ronin's mother declined, saying co-sleeping was the only way she could settle him.
Importantly, the health professionals visiting the family did not report obvious signs of drug use.
The midwife and Whānau Āwhina Plunket nurses said Ronin appeared well during their visits. They reported that his mother did not appear intoxicated and that they observed no signs of alcohol or drugs in the home.
After Ronin died, however, police found an unused bassinet in the main bedroom. A sensor pad was beneath the sheet but was not plugged in.
Police also seized a box containing paraphernalia associated with methamphetamine use. Swabs from the bedroom detected methamphetamine and nicotine.
That raises a difficult practical question for New Zealand's child and maternal health system: how effectively can risk be identified when drug use is concealed or is not apparent during scheduled visits?
The Risks Were Not Isolated
Coroner Mills identified three "modifiable" factors in Ronin's death: cigarette-smoke exposure before and after birth, methamphetamine exposure through breastfeeding and the surrounding environment, and bed-sharing with his mother and sibling.
But the coroner's findings extend beyond one household.
Evidence supplied by the Institute of Environmental Science and Research showed that between December 2015 and 2022 there were 20 infant deaths in which methamphetamine and/or amphetamine was detected.
"Sadly, Ronin and Tiana are not the only babies where methamphetamine has contributed to their deaths," Mills said.
The warning is significant because the underlying drug problem has subsequently become substantially larger.

Methamphetamine Consumption Has Remained at Elevated Levels
New Zealand Police wastewater monitoring provides an unusually direct measure of the scale of methamphetamine consumption.
In the final quarter of 2025, testing sites covering about 77 percent of New Zealand's population recorded an estimated 34.7 kilograms of methamphetamine being consumed every week.
That was more than two and a half times the 13.6kg weekly figure cited for March 2024 in the coroner's findings.
The annual Police assessment found at least 1,751kg of methamphetamine was consumed across monitored sites during 2025, with consumption remaining at the markedly elevated levels first observed during 2024.
The problem has not disappeared in 2026.
Police wastewater results for April to June 2026 estimated consumption at 33.3kg a week. Although that represented a reduction from an exceptionally high April and was broadly consistent with the preceding four-quarter average, it remained historically elevated.
Police estimate the methamphetamine consumed during that quarter generated approximately $34.9 million in social harm every week.
This matters because the coroner specifically linked rising methamphetamine consumption with the danger facing infants.
If the population-level exposure remains elevated, the environment in which cases such as Ronin's can occur has not materially disappeared.
Is the System Designed to Detect the Risk?
Coroner Mills warned that increasing methamphetamine use combined with insufficient and under-resourced rehabilitation services created a "significant risk" that more babies would be exposed.
Her recommendations therefore concentrated on the people and organisations most likely to encounter vulnerable mothers and infants before a crisis.
She recommended additional methamphetamine education, resources and training for midwives, including strategies to reduce harm during pregnancy and after birth.
She also called for the College of Midwives to review the information given to women about methamphetamine and breastfeeding.
Whānau Āwhina Plunket was urged to introduce further training and resources for nurses and health workers.
Health New Zealand was asked to introduce methamphetamine-specific harm-reduction training, resources and strategies across Well Child/Tamariki Ora providers.
There is a sound medical basis for particular concern about breastfeeding.
New Zealand health guidance states that methamphetamine passes readily into breast milk and can affect infants. Maternal use of methamphetamine while breastfeeding is discouraged because of the risks to the child.
But training alone cannot eliminate the problem exposed by Ronin's case.
Health workers were already visiting the family. Safe-sleep advice had been given. A sensor mattress had been offered. The baby appeared well during visits. No obvious drug use was observed.
The risk nevertheless remained inside the home.
When Prevention Depends on Voluntary Disclosure
This exposes one of the central limitations of a health system built substantially around education, observation and voluntary cooperation.
A midwife or Plunket nurse cannot respond to a risk they cannot see or have not been told about.
Nor does the presence of drug paraphernalia after a death establish that visiting health workers could reasonably have discovered it earlier.
That distinction matters. The evidence does not establish that individual health workers failed Ronin.
It does, however, expose the limits of a system in which serious drug dependency may coexist with routine maternal and infant health care without being apparent to those delivering it.
Health New Zealand has pointed to the wider factors often present in preventable infant deaths, including housing conditions, poverty, maternal mental health, addiction, family violence and financial insecurity. It argues that reducing such deaths requires an integrated, cross-agency response.
Coroner Mills agreed that such an approach was needed.
The difficult question is what "integrated" means in practice when the drug itself may remain hidden.
Will This Make New Zealand Stronger?
Will this in fact make New Zealand stronger? Additional education for midwives, Plunket nurses and Well Child providers may improve the chances of identifying danger and reducing harm. But if New Zealand treats this primarily as an information problem within the health system, it risks addressing the consequences while leaving the underlying driver largely intact.
The national wastewater figures point to a much larger problem.
Methamphetamine consumption has risen to levels dramatically above those recorded only a few years ago and has remained elevated despite substantial policing, health and social expenditure.
For ordinary New Zealand families, the consequences extend far beyond individual drug users. They appear in organised crime, household instability, family violence, health costs, child neglect and, in the most tragic cases, the exposure of babies who have no ability to protect themselves.
Ronin's death cannot responsibly be reduced to a single cause. RSV, dehydration, smoke exposure and unsafe sleeping conditions were all part of the coroner's assessment.
But neither can the methamphetamine finding be treated as incidental.
His sister had already died with the same drug detected in her body.
ESR has documented other infant deaths involving methamphetamine or amphetamine.
And New Zealand's national wastewater data shows that the country's methamphetamine market remains extraordinarily large.
The coroner's recommendations may strengthen the protective net around vulnerable infants. Whether that will be enough depends on whether New Zealand is prepared to confront not only how health professionals respond to methamphetamine use, but why so much of the drug continues to reach communities in the first place.
