Regarding the comment about hours of the lane.
Firstly note that the current hours are a trial, set up to conincide with the opening of re-built Westfeild Newmarket mall.
Secondly note that this area is busy 7 days a week. (might change this weekend).
t0ny: Where is the sign to indicate that it is safe to use the bus lane to turn left into Broadway street? You would expect one within 50 meters. Notice the camera next to the Wilson car park, AT captures anyone in the bus lane using those cameras regardless if you turning left to go to Broadway or not.
The buslane end more than 50m from Broadway, as such no usage of the busway is acceptable for the purpose of purpose of turning left to Broadway.
The end of the Busway is marked both with a sign (The same size as the one where it begins, which has been posed here), and paint on the road.
Note that Auckland transport uses enforcement "Zone" - you need to be in the buslane for the full zone (varying length's, but allways over 50m). This is why the automated lane enforcement setups have a pair of camera poles, one for the start of the zone and one for the end.
When I am in the area, most vehicle that breach the bus lane drive it's full length, many even turn right onto Broadway. I don't think the high rate of infringements is to do with issues relating to changing lanes to turn left. I think the issue is to do with the kyberpass intersection by the BP. Coming down the Khyber pass, the bus lane ends prior to this intersection, and due right turning vehicle blocking the right lane, most non turning traffic moves to the left lane. A portion of of this traffic does not merge back into the right lane, and drives down the bus lane instead.
