I am yet to phone the govt to get clear understanding as people hgave differing views. As fas as I am aware you have to return after 6 mths and then wait for another 6 until you can go again but others tell me that they wait a month and they go again...I think it has something to with how many years you have paid tax in NZ..personally I am not hopeful as I spent 19 years out of the country...we shall see...
