The National Reserve Bank of Tonga launched an upgraded family of banknotes into circulation on June 29, 2015. The six denominations are similar to the previous issue but bearing the portrait of His Majesty King Tupou VI instead of his late Brother King Tupou V.
The 6 denominations – 2, 5, 10, 20, 50 and 100 pa’anga – have similar security features to the existing notes, with Optiks™ security thread on the 2 top value 50 and 100 pa’anga and color changing StarChrome® on the lower denominations. The new and old notes will co-circulate for a period of time until the older notes are withdrawn from circulation at the end of the year.
