Bloem was not elected to the Northern Cape Provincial Legislature in the 2019 election, as she was placed 19th on the ANC's list and the party won only 18 seats.[1] However, speaker Kenny Mmoiemang opted against serving in the legislature to go to parliament and the ANC chose Bloem to fill his seat. She was sworn in along with the other newly elected members on 22 May 2019.[2]
On 28 May, premier Zamani Saul appointed Bloem Member of the Executive Council for the newly created Land Reform, Agriculture and Nature Conservation and Environmental Affairs portfolio. She was sworn in on the same day.[3]
Bloem served in the position until her appointment as the MEC for Transport and Safety Liaison in June 2020. She succeeded Nontobeko Vilakazi, while Mase Manopole succeeded her as the MEC for Land Reform, Agriculture and Nature Conservation and Environmental Affairs.[4]
Bloem was not re-elected to the Provincial Legislature in the 2024 provincial election, having been ranked low on the ANC's provincial electoral list.[5]
