If that was the case, we'd be seeing a lot more intercepts in sea containers than we do currently? I can hunt down the report if you are interested, but the amount of weapons seized via sea cargo vs air cargo was massively on the side of air cargo. And its not a case of they aren't looking because we see plenty of drug intercepts in sea cargo.
There are really only 2 ways that legal firearms get into the hands of crims in NZ, straw purchasing and theft.
