People out causing trouble in Whangarei city are being watched and can expect to be caught, say the council and police.
The warning follows a massive spike in recorded misconduct.
Volunteers monitoring Whangarei District Council's 25 closed-circuit television (CCTV) cameras recorded 86 offences and 56 incidents from mid-July to mid-August, compared with a total of 20 for the corresponding period last year. Offences were instances of law-breaking, whereas incidents were bylaw breaches or general issues of concern.
The 142 incidents and offences were also up from 91 the previous month, but council spokesman Owen Thomas said the statistics were a reflection of its focus on increased monitoring, rather than more antisocial behaviour.
He said last year's low figures could be put down to a shortage of CCTV volunteers. Similarly, from April, City Safe officers had started patrolling between midnight and 4am at weekends, rather than just during the day.
