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

"In Nelson, it's important to respect the local Maori culture. Avoid making assumptions or stereotypes about Maori people or their customs. Do not litter or disrespect the natural environment, as New Zealanders take great pride in their country's natural beauty. Avoid comparing New Zealand to Australia, as they are two distinct countries with their own unique cultures and histories. Do not ignore or dismiss the local customs and traditions. Participate when invited and show respect for the local way of life. Avoid being overly loud or boisterous in public places, as New Zealanders generally value quiet and peaceful surroundings. Do not rush or push in queues. Patience and politeness are highly valued in New Zealand society. Avoid discussing sensitive topics such as politics or religion unless you are familiar with the person you are talking to. Do not drive on the right side of the road. In New Zealand, people drive on the left side. Avoid being late for appointments or meetings. Punctuality is important in New Zealand. Do not walk into someone's house with your shoes on. It's customary to take off your shoes before entering a home. Avoid touching someone's head, as it's considered sacred in Maori culture. Do not ignore the 'hongi' when offered. It's a traditional Maori greeting where people press their noses and foreheads together. Avoid using offensive language in public. New Zealanders are generally polite and respectful. Do not smoke in public places. Smoking is banned in all indoor public places and many outdoor public areas in New Zealand," said another expat in Nelson, New Zealand.
