Here in the US, the ringing signal (what the receiver hears) and the
ringback
signal (what the caller hears) are completely separate signals. The
signals
are put on the line by the local central office serving each phone. They
are
completely independent signals and not necessarily in sync. It's quite
common
for one more (or one fewer) rings to be heard by the receiver than the
caller.
I would suspect that this is what is going on in NZ too.

In New Zealand, the system is thus:
One end : RING RING RING RING RING RING
Other end: RING RING RING RING RING RING
So that the same number of rings is not always heard at both ends. It is
never more than one either side though.
