For NZ currency (and other currency, if reproduced in New Zealand), one-sided reproductions are allowed under criteria made public [1] by the RBNZ under Section 30 of the Reserve Bank of New Zealand Act 1989 subject [2] to the following conditions (paraphrased):

• For photographs, drawings, paintings, films and generally for any type of image in which the focus is not the bank notes/coins or reproductions themselves and which do not provide a close-up view of the bank note/coin designs;
• For one-sided reproductions, provided these are more than 125% or less than 75% of both the length and width (or coin diameter) of the respective bank note/coin, irrespective of the material used for the reproduction. Any materials used for coin reproduction must not be metal or metallic like.
