1966 Street Circuit ban, how come they managed to race at Paritutu 1967

There was also Whangarei after that. Also meetings in Hamilton in the 70s. Of course also the Hamilton rounds of the V8 series.
Was it really a Nationwide ban?
I know for fact that it wasn't a ban that stopped Matamata.

the hamilton V8's and wellington street races were a bit differnt, multi million dollar events with wall to wall armco, not your average street race scenario
