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 Hon. Lord Nuku.
The current population of Kolonga was recorded in the Tonga 2006 Census as 1,199. 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.
The name Kolonga did not exist till later on, there were two names that were known; Ualako (old residence home of Hon. Lord Nuku) and the name Mesimasi.
Kolonga village has always been the home and land of Hon. Lord Nuku and his people since the installation of Ngata, Tu'i Kanokupolu. In 1875, when King Tupou I declared the Tongan Constitution, Hon. Lord Nuku was elevated from being an ancient chiefly titleholder to established hereditary noble.
The title, Nuku, has always been passed from the oldest brother to the youngest, not from father to son. Before King Tupou I left for war to Fiji, he entrusted, Hon. Lord Nuku Momoiangaha, to be the King’s Guard at the Royal Palace. When he returned, he was very upset to hear that Moimoiangaha had granted permission for a catholic church in his land. Therefore the title was stripped off.
The title landed among the children of Finauvalevale Finefeuiaki, the youngest brother. His son, Fatanitavake Finefeuiaki, was called to the title but he refused. He along with his sister, Tu’inavu Finefeuiaki, journeyed with Prince Henele Ma'afu 'o Tu'i Tonga to Lau Islands, Fiji. Than the title was bestowed to his brother, Hon. Lord Nuku Nehasi Finefeuiaki, since then the title went from father to son.
