Ok, go ahead and laugh, but I like to be prepared!
Do I have this right on how to get on the road out of the airport heading to the Bay of Islands:
From Airport take 20 North
Cross the Mangere Bridge
Take right on Neilson Street (East)
Take left on 1 heading North through Auckland
I recently read a post from someone from Scotland saying they got lost coming out of the airport... so I thought I'd look into it :)
