It'd be difficult to organise shooting them as they seem to stay within the "100m of a road" firearm exclusion zone

But I wondered about bowhunting them.
I haven't been able to find anything other than the "discharging into a public place" stuff which would require keeping your arrows out of the road reserve.
Anybody know of any other reason they couldn't be controlled with bows?
Anybody aware of an instance where commissioner's approval has been granted to allow shooting pest animals in close proximity to roads?
