From 1967 the coins being used were 1 cent, 2 cents, 5 cents, 10 cents, 20 cents and 50 cents. the 1 cent and 2 cent coins being made of copper and the rest being made in cupro-nickel. In 1987 the 1 cent and 2 cent coins stopped being made and were not used anymore by 1990. In 1991 the 1 dollar and 2 dollar banknotes got changed into coins. They were made of aluminium-bronze. In 2006 the New Zealand Government decided to stop using the 5 cent coin and make all the other coins expect for the 1 and 2 dollar coins smaller. They also made the new smaller 10 cent coin copper.
