Clients searching for a prostitute on a well-known Christchurch city street appear to have been deterred by video surveillance the council installed.
Since the earthquakes street workers have moved away from the city end of Manchester Street, into the residential part of the street.
Their activities have been met with residents' complaints about noise and rubbish.
Councillor Ali Jones organised two mobile cameras as part of a two week trial and said residents had already reported a down turn in the level of activity.
Ms Jones said while the street workers were still turning up, it appeared the cameras had discouraged many of their clients from visiting.
