Dont overthink everything. Apply common sense and have reasonable cause and there wont be an issue. I used to park at Bealey spur in Arthurs pass and do multi days around the tops before dropping into the Waimak river and coming out by the bridge. I then had to walk from the bridge up SH73 back to the spur ( roughly 4 km's ) up a busy road. Always took the bolt and mag out and put it in my pack . You didnt have to be einstein to tell what id been up to . Had a wave from the cop one time ( also had a couple of ghastly stares from the woke left too to be fair) .
