Auckland / North Shore - I've been walking to work the past 7 months or so. My walk takes me along Sunset Rd between Glenfield Rd and the Constellation Park & Ride. 

This part of my walk takes about 20 minutes. During that time I mainly do not have any 3G connectivity and often don't even have GPRS. On one occasion I was on a call talking and sending texts and when I reached the western side of the motorway overbridge my call was dropped, txts wouldn't send...and of course no data as usual. 

It seems odd this road is a black spot as it is the top of the low ridge and you have good visibility in all directions most of the time. The distance is between 2 and 3 kms. 

It's been fairly frustrating as I walk both ways and thus have over 40 minutes of the combined times that I can't do any data. 

Anyone else have any similar urban data deserts on Vodafone?
