In 1933 the Coinage Act authorized a specific New Zealand coinage and removed legal-tender status from British coins. In the same year the Reserve Bank of New Zealand was established. The bank was given a monopoly on the issue of legal tender. The Reserve Bank also provided a mechanism through which the other issuers of legal tender could phase out their bank notes. These banknotes were convertible into British legal tender on demand at the Reserve Bank and remained so until the 1938 Sterling Exchange Suspension Notice that suspended provisions of a 1936 amendment of the 1933 Reserve Bank of New Zealand Act.
