===History===
[[File:Unused proposal for New Zealand Currency (9243555441).jpg|thumb|right|Proposed designs for a $1 (10 shilling) coin]]
On the introduction of the dollar, coins came in denominations of 1c, 2c, 5c, 10c, 20c, and 50c. The 1c and 2c coins were bronze, the others were [[Cupronickel|cupro-nickel]].<ref name="RBNZ">{{cite web |url-status=dead |url=http://www.rbnz.govt.nz/currency/Money/0094086.html |title=History of New Zealand Coinage |archive-url=https://web.archive.org/web/20090123153550/http://rbnz.govt.nz/currency/Money/0094086.html |archive-date=23 January 2009 |website= Reserve Bank of New Zealand |access-date=4 April 2009}}</ref> To ease transition, the 5c, 10c, and 20c were the same size as the sixpence, shilling and florin that they respectively replaced, and until 1970, the ten-cent coin bore the additional legend "One Shilling".  The obverse designs of all the coins featured [[Arnold Machin]]'s portrait of [[Elizabeth II|Queen Elizabeth II]], with the legend ELIZABETH II NEW ZEALAND [date]. The reverse sides of coins introduced in 1967 did not follow the designs that were originally intended for them. Those [[modern art]] and [[sculpture]] themed designs were leaked to a newspaper and met a very negative public reaction. The final releases were given more conservative designs in line with public expectations.

In 1986, New Zealand adopted [[Raphael Maklouf]]'s new portrait of the Queen. The 1c and 2c coins were last minted for circulation in 1987, with collector coins being made for 1988. The coins were demonetised on 30 April 1990.<ref name="RBNZ"/> The lack of 1c and 2c coins meant that cash transactions were normally rounded to the nearest 5c (10c from 2006), a process known as [[Swedish rounding]].

On 11 February 1991, aluminium-bronze $1 and $2 coins were introduced to replace existing $1 and $2 notes.<ref name="RBNZ"/> In 1999, [[Ian Rank-Broadley]]'s portrait of the Queen was introduced and the legend rearranged to read "{{resize|NEW ZEALAND ELIZABETH II}}".

On 11 November 2004, the Reserve Bank announced that it proposed to take the 5c coin out of circulation and to make the 50c, 20c and 10c coins smaller and use plated steel to make them lighter. After a three-month public submission period that ended on 4 February 2005, the Reserve Bank announced on 31 March 2005 that it would go ahead with the proposed changes. The changeover period started on 31 July 2006, with the old coins usable until 31 October 2006.<ref name="RBNZ"/> The old 50c, 20c, 10c and 5c pieces are now no longer [[legal tender]], but they are still redeemable at the Reserve Bank. Prior to the change over, these coins were similar, save for the legend and reverse artwork, to international (mainly [[Commonwealth of Nations|Commonwealth]]) coins of the same British-derived sizes, which led to coins from other currencies, particularly older coins, being accepted by vending machines and many retailers.

Commemorative coins, with face values of 50c, were issued in 2015 and 2018 to mark the centenary of the [[Gallipoli Campaign|Gallipoli landings]]<ref>{{Cite web|url=https://www.rbnz.govt.nz/notes-and-coins/coins/anzac-circulating-commemorative-coin|title=ANZAC Circulating Commemorative Coin|website=Reserve Bank of New Zealand}}</ref> and of [[Armistice Day]].<ref>{{Cite web|url=https://www.rbnz.govt.nz/notes-and-coins/coins/armistice-day-coin|title=Armistice Day Coin|website=Reserve Bank of New Zealand}}</ref>

=== Future ===
After the death of Queen Elizabeth II in September 2022, the Reserve Bank said it would exhaust its existing coin stocks before introducing new coins featuring [[Charles III|King Charles III]]. Based on current stock levels, this would likely be several years away.<ref name=":0">{{Cite web |last=Edmunds |first=Susan |date=2022-09-09 |title=What happens now to New Zealand's coins and bank notes? |url=https://www.stuff.co.nz/business/money/300683373/what-happens-now-to-new-zealands-coins-and-bank-notes |access-date=2022-09-12 |website=Stuff |language=en}}</ref>
