Do you have two or more passports? 

 

I kept getting pulled over because I had - once - used my Canadian passport to leave NZ....and they had no record of me ever arriving on a Canadian passport.  This carried on until my Canadian passport expired......and I made a trip to Canada entirely on my Kiwi passport....(which Canada no longer allows its citizens to do as of June 1st this year - they will now send you back at the border).

 

Anyway....after that trip, I was queried at the gate in Auckland and they explained it was because my passports and my travel didn't line up, so they check. I told them I now only had one passport (My Canadian one had expired and my travel was at short notice)....the Kiwi one...and I have not been checked since. Yes, I got a new Canadian passport a few weeks later as I expected to travel there again soon at that time.

 

But the 'rule' underlying this is that if are entering or leaving a country andyou hold a passport for that country, use that passport only. So now I always leave and enter NZ on my Kiwi passport and always leave and enter Canada on my Canadian passport. No problems. 

 

But in your case...I suspect both the frequency of travel to Asia (you don't say where) and trip to Africa (ebola) are throwing up flags. Or something else. It could easily be something else. :-)  

 

 

 

 

 

Thanks for that detailed reply. I have 2 passports but I always leave and enter NZ on my NZ passport. 

This year I have travelled to India (3 trips), Bangladesh (3 trips), Sri Lanka, South Africa, Australia, Singapore and PNG. My guess is that Immigration have integration to the airlines data so they know where I have been and for how long and some of these countries must be deemed high risk for drugs. Funnily enough when I came back from SA I also couldn't self-process. Iirc when I came back from Aus I was able to.

The perils of frequent travel!
