Police are continuing to negotiate with a man who has been holed up inside a Golden Bay property side before 9am.
The man, who is understood to be alone at the house, is refusing to leave, and has reportedly made threats to set the building on fire.
Fire crews and police are at the scene, including officers from the Tactical Response Group.
At this stage it is not clear what has prompted the incident.
Over the past few hours the man has thrown objects from his balcony, and is understood to have barricaded himself inside.
Residents are not allowed to enter their properties nearby.
Negotiations have so far failed to resolve the situation.
More to come.
