The New Zealand twenty-cent coin is the second-lowest-denomination coin of the New Zealand dollar. The 20-cent coin was introduced when the New Zealand dollar was introduced on 10 July 1967, replacing the New Zealand florin coin. Its original reverse of a kiwi was changed in 1990 when the image was moved onto the one-dollar coin. In 2006 its size was reduced and its edge altered to a Spanish flower as part of a revision of New Zealand's coins, which also saw its alloy become nickel-plated steel instead of cupro-nickel.
