At the end of 2014, Cheng Wen-tsan, then mayor of Taoyuan City, appointed her as the first female director of the Aboriginal Administration of the Taoyuan City Government; and revised the name of the institution which has been used for 14 years to “Indigenous Peoples Administration Bureau”. It took effect on March 11, 2015 and required the name card to be include aboriginal scripts.[16]

In the 2016 general election, Kolas was elected as a legislator under the DPP. The Citizens Congress Watch rated her as an outstanding legislator in the Third Session. Sometimes she write her legislative reports in Amis language.[17]

On the eve of International Mother Language Day in 2016, Kolas promoted “mother language justice”,[18] and proposed amendments to the “Names Regulations”[19] and “Public Officials' Choice of Law”. It suggested that the name of the National Identity Card of the Republic of China can be used without Chinese characters, so other writing systems (such as tribal language orthography) can to used to register the name.[20] It is possible to include both aboriginal languages and Chinese documents together on the election gazette.[21] In mid-December of the same year, the draft Act on the Development of the Languages of Indigenous Peoples was proposed.[22]

In May 2016, Kolas, Chen Chi-mai, and 17 other legislators proposed a bill to abolish the Mongolian and Tibetan Affairs Commission.[23]

On 20 May 2016, 18 legislators including Kolas and Chen Qimai proposed the Draft Amendment to Article 16 of the Immigration and Immigration Law, which was passed on November 1, 2016.[24][25]

On 5 September 2016, Kolas visited the Tibetan spiritual leader Dalai Lama in Dharamsala, India. She was the first Taiwanese aboriginal legislator to meet with the Dalai Lama. The Dalai Lama was very interested in the Amis sash on Kolas. He said that President Tsai Ing-wen's apology to the aborigines was "very good, it is a trend".[26] On the following day, the Human Rights Network for Tibet and Taiwan held their first press conference in Dharamsala.[27]

On 15 February 2017, Kolas accompanied a Taiwanese-Tibetan family to the Executive Yuan to submit a request;[28] on the 20th of the same month, the Ministry of the Interior's Immigration Department abolished the principle of "collective review of the application for residence of Tibetan spouses holding Indian travel permits" and established  “following the Nationality and Immigration Act, Article 16, Item 4, Tibetan residents who have changed their nationality and hold Indian travel permit can apply for stay in Taiwan”.[29]

On 23 April 2017, the Ministry of the Interior, at the request of the Kolas, canceled the ceremony of the Mausoleum of the Yellow Emperor, and the Central Government would no longer sent representatives of the Ministry to attend the Zheng Chenggong Festival, breaking the 54-year political convention and reflecting Taiwan's change in attitude to identity and multiculturalism.[30]

On 17 June 2018, Kolas was invited by the Hawaiki Project (an Indigenous social initiative) to seek funding from the Council of Indigenous Peoples to allow New Zealand Māori children to come to Taiwan on 23 August 2018 for a 10-day origin trip and participate in traditional tribal ceremonies; and at the same time plan in mid-February 2019, allow Taiwanese aboriginal children go to New Zealand to experience Maori culture.[31]

Because of her August 2014 drunk driving record,[32] she has expressed her willingness to serve as an anti-drunk driving volunteer for life.[33][34] KMT members of the Legislative Yuan argued with the social consensus of the "zero tolerance" policy for Kolas to be dismissed.[35][36] Ho Hsin-chun, the head of the Democratic Progressive Party Committee, believes that a person who admits their mistake should be given the opportunity.[37]

On 15 August 2018, when President Tsai Ing-wen passed through Los Angeles, she visited the local 85°C store. Therefore, 85 °C was bombarded by Chinese netizens as a “Taiwan independence enterprise”.  85 °C immediately issued a statement that they “Support the 1992 Consensus”. Kolas Yotaka said she "sympathize 85 °C very much" and also strongly condemns the use of self-righteous ideology in specific countries to suppress free markets and international companies.[38]

On 22 August 2018, the Ngāti Manu tribe of the Maori in New Zealand came to Taiwan for a cultural trace. After arriving in Taiwan, the traditional leader (rangatira) Arapeta Hamilton led the team to the Executive Yuan to thank spokesperson Kolas Yotaka, expressing their excitement in finding a link between Maori culture and Taiwanese aboriginal culture.[39][40][41][42]

On 20 September 2018, at the invitation of Queen Bilung Gloria Salii of the Republic of Palau, she participated in the "25th Anniversary Conference of the National Women's Conference" as the guest speaker.
