Crown copyright

NZ government copyrights 
Almost everything is covered either by regular copyright or, if it is a public service department, by Crown copyright, which in Aotearoa has a 100-year term under Section 26(3)(b) of the Copyright Act 1994. This puts most recent material out of bounds. However, there is an exception to these provisions for some documents:
  -- Some Government departments allow their material to be reproduced free of charge in any format or medium provided it is reproduced accurately and not used in a misleading context. The source of the material must be identified and the copyright status acknowledged. Remember that this is not a carte blanche. See the talk page for a list of web sites that will allow some use — and check the copyright notice first as they are all different.
  -- for works created by some New Zealand government entities, which are covered by Section 27(1) of the Copyright Act 1994 . The section excludes from copyright protection the following NZ works: Bills, Acts, regulations, municipal bylaws, Hansard, select committee reports, court judgments, Royal commission reports, commission of inquiry reports, ministerial inquiry reports and statutory inquiry reports. Note that sourcing these from a third party provider that, say, annotated Acts, is dangerous -- they would have copyright in those annotations, and/or copyright in a new typographical arrangement .
  -- there is list of criteria released by the Reserve Bank of New Zealand for one-sided reproductions of NZ currency without permission. The criteria apply only to exact reproductions. See the template and RBNZ website's reproduction criteria for clarification of the below. Naturally, any copyright is still retained, so fair use may still need to be observed. In short:
 "For one-sided reproductions, provided these are more than 125% or less than 75% of both the length and width of the respective bank note, irrespective of the material used for the reproduction."
 "For one-sided reproductions, provided these are more than 125% or less than 75% of the diameter of the respective coin. Any materials used for the reproduction must not be metal OR metallic like."
