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

"In Napier, it's important to respect the local Maori culture. Avoid making assumptions or stereotypes about Maori people or their customs. It's also considered disrespectful to touch someone's head, as it's seen as sacred in Maori culture. New Zealanders, or Kiwis, are generally laid-back and informal, but they also value honesty, directness, and personal responsibility. Avoid bragging or showing off, as it's seen as bad form. When invited to someone's home, it's customary to bring a small gift for the host. However, avoid giving lilies, chrysanthemums or white flowers as they are often associated with funerals. New Zealand is a country with a strong commitment to environmental conservation. Littering, not recycling, or disrespecting nature in any way is frowned upon. In conversation, avoid making negative comments about the All Blacks, the national rugby team, as rugby is a significant part of New Zealand's culture. Lastly, New Zealanders are generally punctual people. Being late for appointments or meetings can be seen as disrespectful," remarked another expat who made the move to Napier, New Zealand.
