Yes, but in neither New Zealand nor the UK you are necessarily
the only Roderic Page (there may be an unlimited number of
persons with the exact same name). I am willing to bet that the
number assigned to you by the civil administration (which is
intended to be a unique identifier) is different in the UK from
what it was in New Zealand.

Obviously names do depend on taxonomy (and this has nothing
to do with nomenclature). Names cannot be invariant, as taxa
are not invariant. This works both ways:

on taxonomic placement.
Why? Why change the name? This is a convention. If I switch citizenship from New Zealand to the UK I don't have to change my name.
* the same name refers to variously circumscribed taxa (and
everything in between).
Sure, but the name hasn't changed, just what we think it points to.
Only when you assume a God-created nature (with no religious
disagreement on what-is-what), is it possible to have invariancy.
But we can separate the things we point to using names from how we arrange those things. We have chosen not to, with a consequence that we are flooded with multiple names for the "same" thing (however you want to define "same").
Taxa are the result of a process of growth (evolution) and they
do not (naturally) fit into boxes (or into a Tree-of-Life). They have
to be shoe-horned into it, and general agreement is unlikely (thus
no stability). To quote the famous saying: If you want stability of
names, first make sure all taxonomists are safely buried.
