“People are encouraged to examine their cash, including looking and feeling the notes. If you come across any fraudulent notes, please report it to police immediately.”
Loughrin said more information about how to spot fakes could be found on the Reserve Bank website.
Suspected fake cash can be reported to police online via https://www.police.govt.nz/use-105 or by calling 105.
