Foreign Affairs Minister Winston Peters said the online factsheet was a reference to Palestinian refugees.

"It was represented as being the name of a country, when it wasn't. So, it was a ... how shall I put it without being too condemnatory, it was a rather careless and shoddy mistake."

Mr Peters said a minister-to-minister apology would be made if necessary.
