Not Long..... As I work it, you have to first get your UK pension paid here then if that falls short of the Kiwi pension the govt here make it up to what you would get if you only had the UK pension. Its complicated and if you have worked elsewhere and have paid toward their pesion you have to get that paid as well, a friend worked in Canada for a couple of years and they have to get that paid first before she gets her Kiwi pension to top up the amount. If there is a way to get the money back from the UK govt and pay it to the NZ govt I would be interested to hear.
