Also once the kids were born it would've had to have been done anyway to apply for their NZ citizenship. Can't say I've suffered (or even heard of) a single draw-back/con as yet?
I believe, not entirely sure of this though, that an unmarried father has no right of access to or custody of the children in the event of separation. If fact, I think I've read that an unmarried father has no legal rights over his children at all.
