Assault Surge at Palmerston North Hospital’s New Mental Health Ward Highlights Staffing Shortages
6/15/2026, 10:52:50 AM
Background: Nga Wai Ngaro and Prior Concerns
Palmerston North Hospital opened the $67 million Nga Wai Ngaro mental health unit in February 2024, replacing an older ward. Coroner Matthew Bates previously criticised staffing levels after the 2014 suicides of Shaun Gray and patient Erica Hume. Their families, including Shaun Gray’s brother Ricky Gray, have continued to press for higher staff numbers, arguing that inadequate staffing endangers both patients and workers.
Assault Data and Staffing Gaps
Hospital records show 24 assaults on staff in February and 47 in March, with 14 employees forced to take time off after injuries; ten have since returned. The New Zealand Nurses Organisation reported 20 full-time-equivalent vacancies on the new ward. The unit’s floor space is more than twice that of the previous ward, yet staffing rosters have not been expanded proportionally.
Official Health NZ Response
Katherine Fraser-Chapple, interim group director of operations for Health NZ MidCentral, acknowledged a slight increase in aggression, attributing it to “highly unwell patients and adjustments to the new environment.” Health NZ said a violence-and-aggression steering group and a ward-specific violence-minimisation working group are overseeing system-wide improvements, and recruitment remains a focus, though exact vacancy numbers were not disclosed.
Criticism from Families, the Coroner, and Nursing Representatives
Ricky Gray argues that the problem extends beyond numbers, describing a workplace culture “like a cancer” with exhausted, desensitised staff. Carey Hume, mother of Erica Hume, warned that unfamiliar staff and a new layout increase stress for both workers and patients. Grant Brookes, a mental-health nurse and NZNO delegate, linked the rise in assaults to the mismatch between the unit’s larger space and unchanged staffing levels, noting delayed response times when patients become distressed.
Conflicting Reports and Data Gaps
Health NZ’s assault figures pertain only to the new ward and exclude the adjacent geriatric mental-health unit, while raw data released by Ricky Gray combine both locations. Additionally, staff are encouraged to log minor incidents, but contextual details surrounding each event are often omitted, limiting a full understanding of causative factors.
Outlook: Recruitment and Violence-Minimisation Efforts
The hospital continues to fill the identified vacancies and has expanded its violence-minimisation working group, led by the charge nurse, to address response protocols. Ongoing monitoring by the health-system steering group aims to align staffing with the unit’s increased footprint, with periodic reviews planned to assess the impact of these measures on assault rates.
