A review into the mental health care received by triple killer Ross Bremner will remain under wraps at his family's request.
Bremner was an inpatient of the Waikato District Health Board's Henry Bennett Centre when he killed his mother Clare, and Kawhia couple Maurice O'Donnell and Mona Tuwhangai in October last year.
Otorohanga man Bremner, a diagnosed schizophrenic, also left his father, Keith, 64, with serious knife wounds.
Three days later Ross Bremner's body was found alongside those of Maurice O'Donnell, 72, and his wife Mona Tuwhangai, 82, at the couple's property near Kawhia, about 65km away.
Keith Bremner is recovering in Waikato Hospital and reportedly remembers little, if anything, of the incident.
