Move in New Zealand...but more practice English

Hello everyone,
my name is Vincent, I'm Italian.
I am looking for someone with whom to exchange messages or speak in English, to improve the language.
I plan to go to New Zealand to open a business, but English is essential, and the change starts here ..
If there is someone who can 'help also native New Zealander, I'd be happy to do cultural exchange

thank you very much!!!
