This guide is to try and get some consistency in Road type designations used in WME (waze map editor) for New Zealand.
The best reference for Road type designations is found here:
Only differences between NZ and US should be listed on this page
Road Type Classifications
The USA Freeway is the equivalent to the New Zealand motorway
Only roads wirh SH (State Highway) in their official name should be listed as Highways.
Are roads named from SH1 to SH8b
Are roads named from SH10 to SH99
Most other major roads not listed as SH will be "Primary Street"
All other roads
If the road is dirt or any surface that requires a 4 wheel drive, list it as dirt.
Many roads in New Zealand are gravel but can be navigated with a normal passenger vehicle, these roads are not classed as dirt.
