This policy only goes into action if you've already been taken in by airport security for additional screening. Considering NZ got 3.7M international tourists in 2017, this policy will affect only about 1 in every 7000 tourists who visit the country. So unless you're flying in from Iraq or Syria, you probably don't have to worry.
