I guess the RNZ article was simply saying that turning off, or down, outside lights will prevent insects from being attracted to them and harmed.
In summer with windows open, we pull curtains before turning inside lights on. Not seen insects on the open window side of the curtain even with a low level through glow visible.
I’m not sure about the moonlight theory. As they will head towards a bright artificial light, why aren’t there clouds of insects heading out into space every bright full-moon?
Thanks, very interesting.
