I imagine industries that depend on tourism would care, if a decent chunk of potential tourists are smokers. I personally would prefer if there were no smokers (I have asthma), but I could understand that tourism-focused industries would be concerned about turning off groups of tourists that include at least one smoker.
New Zealand is an ecotourism destination, officially and explicitly marketed as such. If anything, banning smoking would increase the perceived quality of their stay for anyone in that segment.
