The Pa'Anga is the currency of the Tonga. It is controlled by the National Reserve Bank of Tonga (Pangikē Pule Fakafonua ʻo Tonga) in Nukuʻalofa. The Pa'Anga is not convertible and is pegged to a basket of currencies comprising the Australian, New Zealand, and United States dollars and the Japanese yen.
The Pa'Anga is subdivided into 100 seniti. The ISO code is TOP, and the usual abbreviation is T$ (¢ for seniti). In Tonga the Pa'Anga is often referred to in English as the dollar and the seniti as the cent. There is also the unit of hau (1 hau = 100 Pa'Anga) but this is not used in every day life and can only be found on commemorative coins of higher denominations.
