A week ago I secured my British passport and it was much easier than I thought. I got my JP to sign and it lasts for 11 years. Moving on to my NZ Passport and it only lasts 5 years and you need to get your photo signed by someone with a current NZ Passport. You cannot use a JP or Doctor anymore.
What if you didn't know anyone with a current passport? 4 of the first people I asked had either lost or it had expired.
