Auckland City Hospital was so overloaded with drunk and injured revellers on Friday that ambulances had to take patients to other hospitals.
The crush reached its peak about 9pm when a record 26 ambulances arrived in one hour at the central hospital - one every 2.3 minutes.
"The ambulances were becoming increasingly slow to unload at Auckland Hospital, just because of the sheer number of them," the clinical director of the adults' emergency department, Dr Tim Parke, said yesterday. "We started to have a traffic jam outside the hospital."
From 10.30 on Friday night until 1am Saturday, ambulances took some patients from the Auckland CBD and surrounding areas to Middlemore Hospital and North Shore Hospital, to reduce the demand on the central city's public hospital.
Even with some patients diverted elsewhere, the Auckland Hospital adults' ED saw 28 per cent more patients than usual across Friday and Saturday, breaking records on both days.
