Remitting money from offshore bank account

[taxhelp]

I have some money invested in New Zealand & would like to get it back to the UK without any tax implications. I won't need the money until later in the year or early next year. Could I send the money to my offshore current account in Channel Is, then open up a savings account (capital only) with the interest paid into the current account, & then at a later date remit the money to my UK bank account.
Would IR look at this as capital being remitted to the UK & thus no tax implications?
How long would I need to leave the money in the offshore account in Channel Is before remitting to the UK.

To answer this we will need to know where you are domiciled, where you are resident, where you are ordinarily resident and the source of the funds...

I am non domiciled & currently non resident. I will be going back to the UK shortly - I had a stint there for just over 4years & left late 2003. The source of funds are from tax paid salary while working in NZ.

Great - this is all capital so can be brought to the UK whenever you like. Incidentally there is no need for a UK bank account since you can maintain capital and income accounts offshore...
