Got to love the guy responsible for speed signs . Leave town 100 speed limit and 30 metres passed that a 30 Kmph U turn followed by umpteen bends with speed sign varying from 30 to 70 don't know when you get to do the 100 Kmph.
Recently was advised to take the tour to Cape Reinga as quite a slow windy road , the way back was the 90 mile beach and apart from the dune surfing stop and the slow trip down the sandy flowing creek most of the trip was at 90 to 100 kmph . Not allowed take a hire car on the beach
