In 1977, coins were introduced in denominations of 1, 2, 5, 10 and 20 cents and 1 dollar. The cent coins were all the same sizes, weights, and compositions as the corresponding Australian coins, with the 1 dollar an equilaterally curved seven-sided coin minted in cupro-nickel. The reverse of each of the six original coins depicts the image of an item or symbol important to native culture, with the most notable being the 10 cent piece depicting Ngoreru, a local sea god from the Temoto region.
