I have an iphone 4 on vodaphone UK, can i unlock and use in New Zealand?

I have an iphone 4 which was on a VODAPHONE UK contract. It ended over a year ago and since I have been using a pay & go vodaphone sim card. If I get my phone unlocked, will it allow me to use it in New Zealand with a New Zealand SIM?

any help would be appreciaited!

Best to have it unlocked

there's some hoops for you to jump through

Ring up vodaphone and ask them to send you the unlock code, if the contract is ended with them then they do it for free, if not there may be a charge
