The New Zealand one-cent coin was the smallest denomination coin of the New Zealand dollar from the currency's introduction in 1967 to its demonetisation, along with the two-cent coin, in 1990. With a diameter of 17.53 millimetres, it is the smallest coin ever issued of the dollar, and at 2.07 grams in mass the lightest as well. Coins issued in 1987 circulated for only three years before they were demonetised on 1 May 1990.
This was the last issue of circulation coins of the one cent denomination in New Zealand. The next year a small number were issued in mint sets only.
