Bad IMEI Iphone import USA to NZ?

I have accidentally purchased a phone online for an Iphone with a bad IMEI. It is an unlocked phone.

It is blocked in the US on networks TMobile and AT&T. I live in New Zealand and I have read up on forums that the phone may work on NZ networks and I have not wasted $500 USD.

Can anyone verify this for me I would be very grateful.

As they continued their journey he entered a village where a woman whose name was Martha welcomed him. She had a sister named Mary (who) sat beside the Lord at his feet listening to him speak. Martha, burdened with much serving, came to him and said, "Lord, do you not care that my sister has left me by myself to do the serving? Tell her to help me." The Lord said to her in reply, "Martha, Martha, you are anxious and worried about many things. There's need of only one thing. Mary has chosen the better part and it will not be taken from her."
