I noticed this morning when I went through Te Rapa (Hamilton) there are ppl in High-Vis coats on Intersection Corners and also on Avalon Drive (just before the rail bridge) with Video Cameras recording all traffic that goes past. Friend of mine said she spotted the same thing in Tauranga also.
I assume here they are looking for people talking on their handheld mobile, guess this is the only real effective way to see if people are on their phones. A police officer doing 100km/h going the other way likely would find it difficult to watch where they are going as well as looking at oncoming traffic to see if they are on the phone
