As the Gazette has been published for more than 185 years, copyright status depends on the publication date of each issue:

1840–1925 (Public Domain): Issues of the New Zealand Gazette and Provincial Gazettes from this period are in the public domain, as the term of Crown copyright (100 years) has expired. Mechanical reproductions (e.g., scanned PDFs) of these public domain documents do not attract new copyright.
1926–1999 (Crown Copyright): Issues from this period remain subject to Crown copyright. Usage of these issues in this project is "Fair Dealing" for research purposes and consistent with the spirit of the open-access principles championed by NZGOAL, ie, "The default licensing position under ... NZGOAL is the Creative Commons Attribution 4.0 International licence ... [t]o the greatest extent possible, agencies should apply this licence to copyright material on their websites"
2000–Present (CC-BY 3.0 NZ): Gazette issues published on gazette.govt.nz are Crown copyright but are explicitly licensed by the Department of Internal Affairs under the Creative Commons Attribution 3.0 New Zealand licence (CC-BY 3.0 NZ). This project redistributes this content in accordance with those terms.

Nothing in this project is intended to infringe copyright, trademark law or personal privacy. Please contact me immediately if you have any concerns.

Third-Party Content

Where third-party content (e.g., notices submitted by external organisations) is identified within the Gazette, users should satisfy themselves regarding the copyright status of that specific content, as it may be subject to different ownership terms than the Gazette itself.
