A 25-year-old man has been charged after a Counties Manukau DHB nurse was stabbed at a patient's home last night.
The DHB said the incident happened when the nurse and a colleague made a routine visit to a patient's home in Otahuhu.
The DHB said the man allegedly pulled a knife and the pair fled but one of them was injured on the way out.
The nurse received stitches for knife wounds and was discharged from hospital today.
The patient was under community health care at the time.
The Counties Manukau DHB said risk was an ongoing issue in mental health services.
Its clinical director for mental health services, Dr Peter Watson said the incident was unexpected, and the DHB always worked hard to minimise risk.
"They were two there and there was nothing at this point to indicate any significant risk, but we'll be going back through this case carefully to see if there was anything that could have indicated such a risk existed."
Counties Manukau police said a 25-year-old was to appear at the Manukau District Court tomorrow charged with wounding with intent to cause grievous bodily harm.
