CPNZ is run by volunteers, so patrols are not rostered or scheduled. Patrollers get to decide when they want to go out, and for how long. John and Lynda both say crime is becoming more prolific and new volunteers are always welcome.
"Our new applicants are tending to be more in the 20s to 40s range," Lynda says.
The pair agree it's nice to be getting some younger new volunteers.
There are a few places that are compulsory to visit, but it is up to the driver to decide how to get there. Compulsory places include community spaces like churches, mosques, synagogues, temples and schools.
John says it is crucial to change routes and destinations for each outing, so as to become as unpredictable as possible.
Observation and deterrence are the two tenets of community patrolling. The patrol's main job is to act as a presence to ward off would-be criminals.
"We're limited in what we can do," he says.
"We've just got to observe, use the phone, use the radio, use the camera, to use these details for later on."
