Yes, those set by the NZTA.
It is illegal to have any numberplate on a car that is not issued by the NZTA.
I have tried for a stick on one for the MR2. Even if it's reflective and in the same font... they say no.
ok, because I went through the legisislation (albeit it was from 2007) and all it had on there was that it had to be reflective and the backing had to be aluminium, so i was after the actual legislation involving this topic.
