We cannot word it as "No" as that is viewed as a word, and people outside of Te Puke would have read it like "No 1 Road" which isn't it's official name however "N° 1 Road" actually is but it can be pronounced as "Number 1 Road" which is the same as "N° 1 Road". I have added in the "degrees" symbol (°) in the names to make it look like the abbreviated word for the word "number" which is "N°" by using the Character Map app that comes with most computers to be able to input it without typing it in with a Qwerty keyboard which is impossible. I have fixed the other N° roads that were written like that too. I hope this helps.
