Rare is a relative term. Most New Zealand Florins were minted in quantities greater than 1 million. New Zealand Florins of which there were fewer than 200,000 minted include the years 1936, 1942, 1944 and 1963. There were 300,000 1946 "Flat Back" Florins (the Kiwi has a flat back) of a total of 1.2 million Florins minted in 1946. What might be considered rare are the Proof Florins. In most years they were minted, there were 200 or less minted.
With the possible exception of traders tokens (with the traders business name on them), there were no "New Zealand" Florins minted prior to 1933. Any Florins circulating in New Zealand prior to 1933 would have been mostly British Florins and perhaps some Australian Florins.
The New Zealand Florin was first minted in 1933 and last minted in 1965. During this period, Florins were not minted in 1938, 1939, 1952 and 1954 to 1960 inclusive.
With the possible exception of traders tokens (with the traders business name on them), there were no "New Zealand" Florins minted prior to 1933. Any Florins circulating in New Zealand prior to 1933 would have been mostly British Florins and some Australian Florins.
