Postal orders were issued in Hong Kong at various times when it was still a British colony.
Hong Kong inland postal orders

Hong Kong-issued British postal orders
editIt is not yet known when these began to be issued in the local post offices, but the last day of issue has been confirmed as 31 December 1993.
BFPO-issued postal orders
editIt is not yet known when these began to be issued at the BFPO, Hong Kong, but the last day of issue for these has been confirmed as 20 May 1997. These issues are extremely sought after by collectors, as Hong Kong was still a part of the Commonwealth when these were issued.
