Speaking at the public forum of the Wanaka Community Board on Wednesday, Sergeant Aaron Nicholson, of Wanaka, said the town had a "very busy'' summer and alcohol underpinned a significant amount of crime, as it always had done.
He explained CCTV cameras were helping identify offenders and the type of offending.
Then he mentioned a family, whom he did not name, which had made a "significant contribution to crime'' but had recently left town.
As a result, he said, police expected to see a reduction in crime in Wanaka.
Not only had the family gone but also their "associates''.
He did not say where the family had moved.
