The armed offenders squad have been called to a Northland house where police have concerns for the mental state of a man.
Senior Sergeant Cliff Metcalfe said officers had cordoned off a property in Whirinaki, after members of the public saw a man in a distressed state this morning.
"At this point police do not believe there is anyone else in the house with the man.
Cordons are in place and a number of staff are responding," said Metcalfe.
