Two people have been killed in a shooting in Auckland CBD this morning. Multiple people are also injured. Police say the situation is now contained and the shooter is dead.

They were alerted to the incident when someone discharged a firearm inside a construction site at about 7.20am.

The gunman moved through the construction site discharging his firearm, police say.

When he reached the upper levels he hid inside an elevator shaft.

Police attempted to engage with him, but the gunman fired further shots, before he was found dead a short time later, they say.
