Hi, We have to head back to Christchurch in a couple days from Nelson (sadly our vacation is coming to an end!). From what I can see the drive time difference if we take the quickest route via the interior (as suggested by google maps) vs. the east coast is about an hour (longer for the coastal route via Picton, Blenheim, Kaikoura. I know google drive times are generally quicker than reality - we've already been around the rest of the island and we are just on our way back to Christchurch. We would like to know about the driving/road conditions for the coast vs. interior route. We would prefer to do the coast with a few stops to eat/stretch as we go, but we don't want it turning into a 15 hour day. Any thoughts are appreciated...
