Stu1: sorry guys dumb question can I set up muiltple apple ids so I can get UK, nz and us apps without an iPhone or iPad, I read that its best to do it out of apple TV as I would need a us credit card?

Yes you can. You also don't need to supply credit card details. The trick is to not be signed into the iTunes store for the country you're interested, and then attempt to download a free app. It'll prompt you to create an account, and when asking for payment details there will be an option to not supply any credit card.

Also, if you have a gmail address, you can use the <username>+<identifier>@gmail.com trick to use a unique email address. For example, if your email address is joebloggs@gmail.com, you could have joebloggs+us@gmail.com, joebloggs+uk@email.com  and so on. All email will go to your joebloggs@gmail.com account, but iTunes will see them as unique email addresses.
