These coins were only issued carded (in a protective capsule embedded in a display card) and were not part of the mint sets or proof sets of the year, which contained the regular "carved Maori head" (koruru) coins instead. The sets however had a five dollar coin with the tuatara design.
The coin is copper-plated steel.
Crowned mature head of Queen Elizabeth II facing right (effigy known as the "Fourth Portrait"). The Queen wears the "Girls of Great Britain and Ireland" diamond tiara, a wedding gift from Queen Mary (Her Majesty's grandmother) in 1947 - which she also has on the Machin and the Gottwald portraits.
In tiny letters below the head, the artist's initials IRB (for Ian Rank-Broadley).
Around the effigy is the monarch's legend and the date: NEW ZEALAND ELIZABETH II 2007.
The last surviving member of an otherwise extinct family of reptiles, the tuatara (a lizard-like reptile), native only to New Zealand, is shown waling on a coastal rock. Above, TUATARA. Below, the denomination 10 [cents].
The tuatara was featured on New Zealand 5 cent coins which were discontinued after the 2006 issue. This coin, although of a different design, is a reference to them.
