Police in Northland say they were acting with the best intentions when unlawfully using road blocks to gather intelligence.
The police watchdog has found the officers illegally detained a woman and breached her privacy by photographing her and her partner at a checkpoint in Northland in 2019.
Officers set up checkpoints near a 'fight night' gathering to collect intelligence on the many gang members they knew would be attending.
Northland Police District Commander Tony Hill admitted to RNZ reporter Jordan Bond the practice has been happening for years.
