Auckland Council has announced a crack-down on window washers throughout the city as the council receive up to 40 complaints a month from motorists.
Last week police in South Auckland announced a trial of a new initiative to combat the window washing issue around the district.
Max Wilde, Manager Bylaws and Compliance for the council, said motorists were frustrated.
"We are receiving up to 40 complaints a month from frustrated motorists who are concerned - and often intimidated - by the behaviour of window washers.
"The safety of drivers is paramount and we are working together with police to identify intimidating window washers and take action against them."
Auckland Council said over the last six to eight weeks evidence has been obtained relating to more than 220 separate offences in breach of Auckland Council's Public Safety and Nuisance Bylaw.
Council staff have collated information on more than 60 individuals who regularly take part in this activity and are working with police to identify offenders. Trespass notices are being considered to deter prolific offenders from reoffending, the council said, and prosecution was more viable for the council because of police assistance.
A recent joint operation with the police saw council focus enforcement on an intersection in Mt Wellington where 13 people were engaged in window washing over a two day period.
The identities of those involved were obtained by police and council will be pursuing enforcement action through the courts.
As well as breaches of council bylaws, police arrested several individuals for various unrelated criminal matters.
Inspector Ross Barnaby said police came across young people window washing who should be at school, including a 13-year-old who had been reported missing by his parents.
The police brought him home and encouraged other youths to continue with their schooling or training to improve their chances of achieving more long-term secure job opportunities, Mr Barnaby said.
Police were concerned about the number of individuals found window washing who have outstanding criminal matters, Mr Barnaby said.
Council staff and police believe drivers also have an important part to play in helping resolve the window washing issue. Money is the motivation for window washers and drivers should discourage window washers at intersections and decline to pay them.
