Thread: Firearms in Vehicles

I recall a news story about a guy from timaru, that was driving to Christchurch to deliver his gun to a gunsmith,
Rather than leave it unattended in his vehicle (a violation of the arms regulations 1992) he brought it with him when he stopped into to the public toilets in Ashburton, and was arrested by police for Carrying or possessing firearms, etc, except for*lawful,*proper, and sufficient purpose. (A violation of the arms act)

To my knowledge the arms regulations don't include prescribed penalties or offenses but for a violation of them and police can decide your no longer a fit and proper person.
The arms act 1983 does have offenses sections with fines and prison time, Possible on conviction.
So faced with possible arrest and criminal charges or a regulatory infraction and possible loss of licence which should you choose?
