Hi, Check your local bank and then call the Prestige Group in Dublin (from memory their no is 01-6686036, but a web search will bring them up, they are a property sales based company) and ask for the foreign currency department. Say you want a rate to transfer money to a NZ bank account and ask for a rate. If you are happy with the rate then you proceed with registering and authorizing the transaction. The funds will transfer quickly. We use them regularly and their rates are much better than the bank in our experience. If you have an AIB or BOI account look for their acount with that bank as it will save you on transfer fees from your own bank and the funds hit their account immediately.
Hope the move goes well. My wife is from NZ.
All the best Optimistic
