As for UK imports to New Zealand, if you think only a few you are wrong.

I was talking specifically about species of earthworms, and the
information was from a source I trust.

Try
loads.

Of species of earthworms? If you can let me know which species of
earthworm have been imported from the UK to NZ, I'll challenge my
source.

I was posting in *support* of your thesis that your quoted url was
relevant to the UK - don't jump down my throat!
