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

"In Hamilton, it is considered rude to not wait in line or to push ahead of others. It's important to respect personal space and not stand too close to others. It's also considered impolite to be overly loud or boisterous in public places. New Zealanders value punctuality, so it's considered disrespectful to be late for appointments or meetings. When invited to someone's home, it's customary to bring a small gift for the host, such as a bottle of wine or chocolates. It's also polite to offer to help with cleaning up after a meal. It's considered disrespectful to litter or damage the environment in any way. New Zealanders are very proud of their natural landscapes and work hard to preserve them. Avoid making jokes or negative comments about the Maori culture, as it is deeply respected and valued in New Zealand. In conversation, avoid discussing personal wealth or income, as it's considered impolite and boastful. Lastly, while New Zealanders are generally friendly and informal, it's still important to use proper titles and surnames until invited to use first names," said another expat in Hamilton, New Zealand.
