Worth popping into local tax office. They were very useful when i went in to find out about how i would be taxed on rent earned on a property in the UK while living abroad. There is a whole dept of the tax office that deals with these sorts of queries. You are right, there is a dual tax agreement that means you wont be charged twice on same income. I was told by tax office that i would be taxed in UK on income earned in UK (e.g property rental) which is great as you then make use of your £5k personal tax free allowance (which you don't get in NZ). Not sure how this work for living in NZ earning money from work for a UK company though. I guess if you are paid in sterling into a UK bank acct then the same rules would apply - you are taxed on UK income. I'd be interested to know what you find out.
