 (III, Tuapasi).

He was selected by King Siaosi Tupou II to marry his oldest daughter and heir, Sālote, even though she was 12.5 years younger than he. The wedding took place on 19 September (Christian ceremony) and 21 September (Tongan ceremony, the tuuvala) 1917, less than a year before Siaosi would die and Sālote would be crowned as queen.

The marriage was a success. Tungī's personality and status did a lot to elevate the esteem of the people towards their queen. Furthermore, their children born would carry the combined bloods of the 3 major Tongan royal dynasties. Tungi would always be remembered as very generous to all his relatives. His death in 1941 was a heavy blow not only to Queen Salote but to all Tungi's relatives and kainga.

Despite the respect he had for his wife, Tungī had many girlfriends everywhere around. But Tulu from his hometown Muʻa was his favourite and he visited her perhaps every week. Also that day when he and Sālote had welcomed a contingent of Australian mariners from the airport. While Sālote returned town with them, he used the opportunity to have a short detour to Muʻa. On this specific occasion he collapsed while with her.

Tungī was educated at Tupou College, Tonga and Newington College, Sydney. He was a follower of the Methodist Church. Tungī was a CBE and was also prime minister of Tonga from 1923 until his death.
