The Waitemata District Health Board is concerned by claims an after-hours mental health crisis line caller was told to wait until the next morning for help.
An Auckland woman called a 24/7 helpline at night and was "devastated" to be told to wait until the next day for help, Stuff reports.
The 23-year-old was told by the Board's after-hours north crisis team unless she could get to the North Shore Hospital's inpatient unit, help was unavailable until the morning.
An operator told the woman the on-call clinician was asleep at the time.
In a statement, the Board said it would be "unacceptable" for their 24/7 helplines to be unstaffed and for members to be asleep for essential services.
