One person was taken to Auckland Hospital in a critical condition, St John said.

A police spokesperson later confirmed armed police were now on Stewart Rd in Mount Albert and “carrying out inquires” relating to the incident. A photo from the scene shows a group of men detained by police and sitting on the ground.

Police said they are making inquiries into what happened.

“We would encourage anyone who may have seen what happened who has not yet spoken to police to please come forward,” a spokesperson said.

The police helicopter is continuing to circle above West Auckland. Earlier a constant wail of sirens could be heard as emergency services rushed to the scene on what is one of the suburb’s busiest streets.

A video posted on social media after the incident shows two ambulances at the scene as well as at least three police cars and a fire truck.
