Banknotes
In 1967, notes were introduced in denominations of $1, $2, $5, $10, $20 and $100, with all except the $5 replacing their pound predecessors. The original series of dollar notes featured on the obverse a portrait of Queen Elizabeth II wearing Queen Alexandra's Kokoshnik tiara, King George's VI festoon necklace, and Queen Mary's floret earrings, while the reverse featured native birds and plants. The notes were changed slightly in 1981 due to a change of printer (from De La Rue to Bradbury, Wilkinson & Co.) - the most noticeable difference being the portrait based upon a photograph by Peter Grugeon, in which Queen Elizabeth II is wearing Grand Duchess Vladimir's tiara and Queen Victoria's golden jubilee necklace. The $50 note was added in 1983 to fill the long gap between the $20 and the $100 notes. $1 and $2 notes were discontinued in 1991 after being replaced with coins.
A new series of notes was introduced in 1992. The obverse of each note featured a notable New Zealander, while the reverse featured a native New Zealand bird and New Zealand scenery. In 1999, polymer notes replaced the paper notes. The designs remained much the same, but were changed slightly to accommodate new security features, with the most obvious changes being the two transparent windows.
