Looks like I'm going to New Zealand end of this year/early next year and will be stay there for a while. Does anyone know what's the price of 123a battery like over there? Just thinking if I should bring a few with me or buy them there. Also will there be any problems bringing a multitool and folding knife with me? I heard the law there is pretty strict, and cop can arrest people for having a screwdriver if he wanted.
