BTW, what's Israel so interested in New Zealand for?
If I had to guess, they didn't want the passport to enter New Zealand, but to enter another country AS a New Zelander.
They did the same thing once with Canadian passports they obtained illegally and used to enter Syria in order to assasinate a Hamas leader that was living there. You can imagine how upset the Canadians were when they found out about it-they recalled their ambassador).
