firstly, NZ do not overtake you even when you are toddling along in a slow camper van unels
1 you give them a written invitation
2. pull off the road completely (two wheels left on the road is no good)
3. the road is completely straight
4. the road is completely empty (another car a mile off is just way too dangerous!)

New Zealand roads have sign posts on them for everything
every tiny stream is named and labled
every bridge is numbered and labled
driving up to the opara basin you will even see a signpost for "a large tree" the fact that no one in their right mind should stop in that location to admire said tree is beside the point.
ever corner has a very conservative speed limit put on it, apart that is from those corners that you really cant take at more than 10mph and there is a 200 foot cliff to the side - those they neglect to put anything apart from an odd descrete marker indicating that the ground is actually sliding away at the side, so don't try and pull onto the verge

The New Zeland idea of a crash barrier on an extremely dangerous bend is a small wooden kickboard painted white. I assume this due to their love of extreme sports - if you need a crash barrier, you are going to fast lol

The term "motorway" at least in the south island is used in the most liberal sense of the word, a road being called a motorway does not guarantee you a dual carriage way for the full stretch. Nor even when dual carriage way, does it guarantee you a central reservation.
