I am wondering two things, firstly I have been told sim cards came in 2 sizes, credit card and mini (what we use now).
Did we ever have phones with the credit card sized ones, or did NZ totally miss out on them?

Secondly I hear sim cards can operate at 3V (modern) or 5V (older), so I want to know is the difference in voltages in relation to the difference in physical size between the credit card sized sims and the normal mini sims, OR is the difference in voltage to do with step between SIM1 and SIM2 sim cards OR a cutoff in memory size, eg (this is not what I've read, just purely an example to convey the message) all simcards before 16K are 5V, 16K onwards are 3V???

Not sure if they were comon, but I had a Motorola that used the "full" Credit card size sim.
Long since gone.  Back in 1997 if memory serves me correctly.
My mate had a Nokia that used one as well.
