Police are hunting a suspected assailant late this morning after a person was critically injured in suburban Auckland last night.

Hato Hone St John was sent to Māngere Bridge in South Auckland just after 6pm, dispatching an ambulance and two rapid response units, a spokeswoman said.

“Our crews assessed and treated one patient who was transported to Auckland City Hospital in a critical condition.”

Police were alerted to an alleged assault on Coronation Rd about 6pm, a spokeswoman said.

The alleged offender wasn’t found, with inquiries continuing today, she said.

The injured person is in hospital in a stable condition.
