Hingano ran in the
2010 Tongan general election but was unsuccessful. He was elected to the
Legislative Assembly of Tonga at the
2014 election, but his election was disputed, leading to a recount, which he won. In parliament, he generally sided with the Noble faction, opposing the government of
ʻAkilisi Pōhiva's decision to withdraw from hosting the
Pacific Games, and opposing it in confidence votes. In June 2016 he advocated for higher salaries for MPs. Hingano was defeated at the
2017 election, losing to
Moʻale Finau. In January 2021 he was appointed Governor of
Haʻapai by Prime Minister
Pōhiva Tuʻiʻonetoa. Shortly after being appointed he was convicted of unlawful possession of 198 kg of turtle meat. He was fined T$12,000, but allowed to retain his position. He was re-elected to the Legislative Assembly at the
2021 election. On 28 December 2021 he was appointed to the Cabinet of
Siaosi Sovaleni as Minister for Agriculture, Food and Forests. Immediately after being appointed he flew to New Zealand for medical treatment. Hingano died in Auckland on 10 June 2022 at the age of 47. ==References==
