I checked on Wises.co.nz - that had a more straight forward journey. London Road - Hutt Road.
I was just in Lower Hutt, never go there, so I had with me my Nokia. I was in London Road I took the exit off the motorway into Petone by mistake b/c it didn't tell me either to keep going or take the left exit. So I was on London Road and it said keep going up that road for 15mins ... and back down might have been London Road again .... then it was a short drive to Hutt Road. What ..... So did my Nokia asked me to do a full circuit instead of a u-turn??
