on the now withdrawn 1 toea coin. Banknotes On 19 April 1975, notes were introduced for 2, 5 and 10 kina that replaced the Australian dollar at par, so the colour scheme was the same. They circulated along with the dollar until 1 January 1976 when the dollar ceased to be legal tender. The 20 kina was introduced in 1977, 50 kina in 1988, followed by 100 kina in 2005. All colouration of the individual denominations are the same as current and former Australian decimal currency. Beginning in 1991, Papua New Guinea's banknotes have been produced on polymer, although in 2009 the bank issued Kina & Toea Day commemorative notes on paper substrates. A new issue of banknotes has been issued starting with the 50 kina in 1999, then the 100 kina in 2005, 2 and 20 kina in 2007 and the 5 and 10 kina in 2008. This makes all the denominations of the kina issued in polymer. Paper bank notes ceased being accepted by the Bank of PNG from 31 December 2014, and are no longer legal tender.
