Two hearses have been seen leaving a Clendon Park property where a large number of police, including forensic staff in boiler suits, have been since Thursday afternoon.
An RNZ reporter had earlier seen a body being loaded into a hearse, and a neighbour told the Herald they understood a body had been found at the Moncrieff Ave property.
Neighbours in the street were angry police were keeping them in the dark.
Two adults and two children have been living at the house for about six months, RNZ understands.
Police would only confirm they responded to an "incident" at the South Auckland property and there was no immediate risk to the public in relation to that.
