The restrictions on trademark registration in New Zealand mainly include the following aspects:

1. Similarity restrictions: The New Zealand Trademark Office will compare the similarity between the trademark application and the registered trademark. If a trademark is too visually, audio- or conceptually similar to a registered trademark and may cause confusion, the applicant's application for trademark registration may be restricted or refused.

2. Unacceptable trademarks: The New Zealand Trademark Office prohibits the registration of certain types of trademarks, such as trademarks that are offensive, deceptive, confusing or immoral. Trademark applicants must ensure that their trademarks do not violate public order, social ethics, or laws and regulations.

3. Other rights restrictions: Trademark applications may be restricted by other rights, such as other people’s trademark rights, copyrights or well-known brand rights. Applications for trademark registration may be restricted or refused if the trademark conflicts with the rights of others.

4. Public interest restrictions: In some cases, the New Zealand Trademark Office may impose restrictions on trademark registration based on public interest considerations. For example, a trademark registration application may be restricted or refused if the trademark is deemed to mislead the public or cause public harm.

It should be noted that the above is a general overview of trademark registration restrictions, and specific restrictions vary depending on the situation. Before making a specific application, it is recommended to consult the New Zealand Trademark Office or a professional trademark agency to obtain the most accurate and up-to-date restriction information and guidance.
