I returned to NZ and have had to renew my NZ passport while I am here. One can do so completely on line if there is a current passport, and you have to nominate a referee if they want to check up on you. The great thing is that I can take my own photo via a site that I can submit the image to and I get immediate feedback as to whether the image is acceptable or not. On the on-line application I give them my passport details, confirm my address and upload the photo- - and of course pay them!
When I did the upload I got an immediate email response to advise that the application had been received and that it could take up to 10 working days to process. That was at about 8:30am. At 12:40pm the same day I got an email that my passport has been processed, approved and printed and will be with me via courier in about 3 days.
I particularly like the idea that I can take my own photo. In Canada I shall have to a similar renewal, this time on paper and pay an authorized company to take my photo.
This last experience what I call service in the 21st Century - Kudos to the NZ Dept of Internal Affairs!!!
(Remember - if you look like the photo, you need the vacation...)
