Nyarku stood for the National Democratic Congress' primaries ahead of the 2020 elections.[7][10] He won the parliamentary bid to represent the National Democratic Congress for the Constituency in August 2019 after he went unopposed due to the disqualification of his two contenders.[11][12]
On 16 July 2020, ahead of the elections during the compilation of a new voter's register, he was disqualified from holding a voter's ID card due to claims of registering in a suburb of Cape Coast, Nkanfoa, where he had not been a resident for a number of years as required by the registration laws.[13][14][15] His eligibility was challenged by a polling agent of his opponent's party the New Patriotic Party (NPP) and referred to the District Registration Review Committee.[13][16] The District Registration Review Committee upheld the challenge and in August 2020, he filed an appeal against the decision which was dismissed by the Cape Coast High Court.[16][14][17] On 22 September 2020, based on points raised by his lawyer Godwin Kudzo Tameklo, an Accra High Court, with the presiding judge Justice Stephen Oppong issued a write of mandamus compelling the Electoral Commission to register him since no court of competent jurisdiction had barred him from registering.[16][18][14][17]
On 1 October 2020, he was registered in accordance to the ruling of the Accra High court.[19][20] The issuing of the new ID card prompted another challenge by the New Patriotic Party which was this time quashed by the District Registration Review Committee by a 5:2 majority vote paving way for him to file his nomination to contest in the parliamentary elections.[20][19]
In the 2020 Elections, Nyarku beat the incumbent member of parliament Barbara Asher Ayisi of the New Patriotic Party,[21] who doubled as the deputy minister for works and housing and was a former deputy minister of education.[22][23] He garnered 22,972 votes against her 21,643 votes representing 51.49% and 48.51% respectively to be declared winner and member of parliament elect.[24]
