Council community services general manager Simon Pickford confirmed it had more than 20 complaints about nearby addresses with Building Act non-compliances and most if not all resulted in the discovery of structures which had to be altered or removed.
It started with a neighbour issuing a complaint about Mr Anderson's property.
Council policy meant the property of the person who made the complaint was also checked and non-compliant structures were found there also, Pickford said.
This person later sent a list to the council of houses in the area with similarly non-compliant structures.
This was accompanied by photographs which seemed to have been taken from a drone.

New Zealand law requires consent from owners of properties over which drones are being flown and drones are usually not allowed to be used within 4km of an aerodrome, which this area is.
