The Otago Daily Times has reported on incidents at the rest-home which involved complaints from staff and family about management and the handling of residents.
WorkSafe had investigated and had previously told the Otago Daily Times it had met the business owners to understand how they were managing psychosocial risks.
It said a site visit was not required and said the company had advised it was beginning work to make improvements.
But complaints have continued.
The daughter of a woman who died early this year said her mother was there for less than a year and "her care was terrible; she felt unsafe and they did little to help her".
"My mother decided to stop eating and drinking and Oxford did nothing, not even telling me who was her power of attorney."
She said the rest-home did not appear to want to help her mother.
Hospital files showed she was covered in bed sores from when she was at the rest-home.
"It disgusted me and, as an ex nurse aide at rest-homes, [I] was horrified this happened."
She said when her mother was put in palliative care the rest-home was "combative and argumentative with me".
"They refused to believe there was anything medical wrong with her, disagreeing with the doctors and pitting me and my siblings against each other.
"This caused me massive stress and ruined relationships.
"I believe they were partially responsible for mum’s death. For the $6000 a month we paid for her to be cared and looked after, they did not deserve that money and never earned it."
She complained but said she was fobbed off.
A WorkSafe spokesperson said an internal investigation by rest-home owner New Zealand Aged Care Services Ltd (NZACS) found the allegations were unsubstantiated.
WorkSafe determined a site visit was not required as it was not the best-placed agency to respond, the spokesperson said.
The issue involved employment relations — an area regulated by the Ministry for Business, Innovation and Employment.
No residents or family had approached WorkSafe.
Any such concerns would be more appropriately received by the health and disability commissioner, who investigates complaints about health and disability services, including aged care.
He said WorkSafe’s response was not an investigation.
"We received a notification and engaged with NZACS to reiterate its obligations under the Health and Safety at Work Act 2015. WorkSafe would only revisit the case if new information is notified to us that is relevant to work health and safety."
It is believed former and current staff at the rest-home have put in personal grievances against management.
NZACS said last Saturday it was aware of the concerns raised in relation to Oxford Court.
The company had worked with WorkSafe NZ and no further action or involvement was proposed.
