SomeoneSomewhere:I believe NZTA has rules that pretty severely dissuade pedestrian ('zebra') crossings on major roads.
As above, there are few other options aside from no crossing, cross at own risk, or various degrees of traffic light.
It's not the pedestrian crossings that are the problem, it's the crazy dumpster fire of roundabout, speed tables, crossings, traffic lights, and just the right spacing between the roundabout and crossing to trap vehicles in there stalling the entire roundabout. It's like they took every single traffic-disrupting element they could and threw it all together into one mess.
Here's a simple, time-tested solution that does away with the entire mess, and in fact is what exists everywhere else on the same road: A four-way intersection with traffic lights and pedestrian crossings.
