Sunflower Student Movement, Huang joined the
New Power Party (NPP) in May 2015. In July, he was named acting chairperson and subsequently served on a seven-member committee of party leaders, including
Freddy Lim and Neil Peng. Huang ran as an NPP candidate in

Kuomintang legislator Lee Ching-hua and was assigned to the Finance Committee. On 16 December 2017, a

held against Huang over his support for
same-sex marriage. Votes in favor of the recall outnumbered those against, but fell short of the required threshold of one-fourth of the district's total electorate. Huang stepped down as chairman of the New Power Party in January 2019. On 22 July 2019, Huang, as a New Power Party legislator held a press conference titled “Smuggling While Accompanying on an Official Trip—National Security Bureau, Come Out and Face the Issue.” He accused a

allegedly taking advantage of accompanying President
Tsai Ing-wen on an overseas visit to pre-order 9,200 cartons of
duty-free cigarettes through senior
China Airlines officials, amounting to NT$6.45 million, and attempting to bring them into the country by exploiting the special diplomatic customs clearance privileges. In June 2019, Huang stated that he would leave the New Power Party if it became a "sidekick" of the
Democratic Progressive Party, but he denied that he was forming a new political party.
