What cultural faux pas should I try to avoid making in Dunedin?

"In Dunedin, it is considered rude to not respect the local Maori culture. This includes mispronouncing Maori words, disrespecting Maori customs, or making light of their traditions. It is also considered impolite to litter or disrespect the environment in any way. New Zealanders are very proud of their natural landscapes and work hard to keep them clean and preserved. Avoid making loud or obnoxious behavior, especially in public places. New Zealanders value peace and quiet and may find such behavior disrespectful. Do not assume that everyone in Dunedin is of British descent. New Zealand is a multicultural country with a diverse population. Avoid discussing sensitive topics such as politics and religion unless you are very familiar with the person you are talking to. New Zealanders are generally open-minded, but it's always best to err on the side of caution. Do not compare New Zealand to Australia. While the two countries may seem similar to outsiders, they have distinct cultures and histories. Lastly, tipping is not customary in New Zealand. While it is not considered rude to tip for exceptional service, it is not expected and can sometimes create awkward situations," remarked another expat in Dunedin, New Zealand.
