A police operation is under way in Papakura where a man is thought to be inside a property with a gun.
Armed Offenders Squad have raced to Sutton Crescent and Rollerson Street area and police are asking people to keep away from the area.
A police spokeswoman said a negotiator was now attempting to persuade the man at the centre of this morning's incident to come out of a house.
It was unclear if anyone else was inside the property with him, she said.
A resident told the Herald armed police cordoned off the area at 8am. Police cars were stationed at either end of the normally busy Rollerson St.
People were warned to stay indoors while the operation unfolded.
