at the risk public ridicule and of rehashing something that may have been mentioned in the last 10 pages I haven't read:
lets say that in section 5 'permanent nationality that is not dependent on residence in a certain Country' does not include Declan as his passport / NZ nationality was based on residence in this country.
lets get urgent legislation passed to say that Declan Wynne has an NZ passport / is an NZ national 4 life (i.e. not dependent on residence). lets make that retrospective to say, when he was born. therefore section 6 applies and he meets the 2 years?
your welcome NZ.
