Eric sent this in:
As I was walking along Tamaki Drive about 8:38am today (Saturday, 26th February) near the Ngapipi Rd I heard the cry of a cyclist “[BUZZ] ME DEAD”, as I looked up there was a car turning right from Tamaki Drive into Ngapipi Rd in the stop position blocking half the road for oncoming traffic, with two cyclist fast approaching.
[I've] been aware of the electronic sign that lights up when cyclist approach that intersection from the Okahu Bay direction, thought I could use a photo of that sign in a upcoming webpage.
As I stood on the traffic island waiting for the sign to light up so I could take a photo, I noticed that a cyclist came towards me and the sign did not light up.
After I took the photo I decided to stand on the footpath (in the shade of a lamp post) and waited about ten minutes for cyclist to come along, for about five minute everything worked fine, cyclist came — sign lit up, cyclist went — sign turned off, then twice within a minute cyclist came but no sign of sign lighting up.
So I suppose one could come up with the theory:
Motorist are putting too much faith in a faulty sign that does not light up when it should, so they proceed, then having to stop halfway in the other side of the road when they make visual contact with oncoming cyclist.
The top of page of the fax was not only posted on FixMyStreet but also faxed to the police on 0800 161610 the only best fax number I could find in the telephone book.
I went back this morning (Sunday, 27th February) thinking has this been fixed or is there a temporary warning sign for motorist saying something like ‘intermittently faulty’
I got there at 8am and waited cyclist came and went everything worked right, then at 8:18am four cyclists heading for the city never lit up the cyclist sign that would help motorist avoiding a incident.
(Thanks, Eric!)

I suggest that you call Auckland Transport, first try the call centre, then Debbie Lang directly
I see "Fiona M" made a comment at http://fixmystreet.org.nz/issue/1092 "Right turn from Ponsonby Road to Great North Road leaves cyclists stuck", is this a problem unique to this intersection? I should imagine at happens all over every intersection, AND WHY DONT MORE PEOPLE ON TWO WHEELS WEAR HIGH VISIBILITY VESTS !?!?
Hi Eric, I'm not sure what wearing hi-vis has to do with traffic light sensors that don't cater to cyclists …
I also remembered that we had an earlier discussion about traffic light triggers here:http://cyclingauckland.co.nz/rules/2010/05/car-triggered-traffic-lights/
