I flew out though Wellington last week, and was told I could keep my laptop in my bag, no doubt due to the new CT scanners.
I know Auckland has these at the International terminal, but have they reached domestic yet? where else in the country?

So after traveling this week, yes I had to take out the laptop leaving Auckland, but leaving Christchurch they wanted laptops in your bag and had signs up to that effect.
