Business directory for Tonga - no keyword search and if you click on any of the letters or categories, an alphabetical (mostly) list starting from A is shown. You need to scroll down the list to find the company you're looking for and some additional companies are added at the bottom not in the right order. Not too bad if the list is short but it's not the most user friendly format for finding information.
Basic list format directory for a number of organisations, businesses and government contacts in Tonga. Includes some mobile numbers and email addresses as well.
