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"
