Kolonga is a village and the most populated settlement located on the northeast coast of Tongatapu in the Hahake District, Kingdom of Tonga. Kolonga is a hereditary estate of Lord Nuku.
The current population of Kolonga was recorded in the Tonga 2006 Census as 1,199.[1] Many people have left to go overseas for better opportunities. Many lands have been deserted or they leave it to the care of their relatives, sending money support back home. The majority of the residents owned two lands: one in town where they reside and one agricultural land in the bush.
Nearly 99% of the population are agricultural farmers, out of that population only 60% own some level of qualification to a degree. Only a few have government jobs, while the rest make money out of their farming supplies at Nuku'alofa, the capital city of Tonga.
