The Police Armed Offenders Squad has been called out to Gate Pa, in Tauranga.
Witness Mitchell Robinson, who works two buildings away, said six armed police are on Wilrose Place, yelling for a person to exit a building with their hands up.
"I can see about six police in the full black with the face masks on and holding these big rifle guns and stuff."
Police have confirmed the AOS is executing a search warrant on the street in relation to an ongoing enquiry.
Earlier today a man died after being dropped at the door of Tauranga Hospital with critical injuries.
It's not clear whether that's linked to the Gate Pa callout.
