Biography

Ng Kor Sim (born 1983) is the Democratic Action Party (DAP) assemblyman for the Jementah state constituency in Johor, a seat she has held since winning the 12 March 2022 Johor state election under the Pakatan Harapan (PH) ticket [1]. Prior to entering politics, she served as the general manager of a private company [1]. She has also been identified as a single mother who has actively participated in community activities since 2015 [1]. In the 2022 Johor state election, she won a three-way contest against Barisan Nasional (BN) and Perikatan Nasional (PN) candidates, securing 8,877 votes with a majority of 714 votes [2]. Jementah was among seven Johor seats decided by fewer than 1,000 votes in that election, making it one of the state's most closely contested constituencies [2]. Within the party, Ng holds the position of treasurer of the Johor DAP state committee, a role she retained after the October 2024 Johor DAP elections [3]. As an assemblyman, she has raised issues relating to cost of living, transport logistics, and disaster preparedness for her constituents. Jementah is a constituency whose economy is largely rooted in agriculture, situated under the Segamat parliamentary seat [4]. She was re-nominated by PH as the DAP candidate for Jementah in the 2026 Johor state election, with polling day set for 11 July 2026 [1].

Known for

Ng Kor Sim is known as the Jementah assemblyman who won one of the most closely fought seats in the 2022 Johor state election, securing victory with a majority of only 714 votes in a three-way contest [2]. She has been vocal on bread-and-butter issues affecting her predominantly agricultural constituency, including the impact of transport enforcement on commodity supply chains and the cost of living [5]. She serves as treasurer of the Johor DAP state committee [3].

Political positions

On cost of living and logistics, Ng has urged the Road Transport Department (JPJ) to review its crackdown on overloaded lorries, arguing that higher operating costs for oil millers and the construction sector would be passed on to consumers through higher prices of goods and services, placing further strain on cost of living [5]. She noted the enforcement also disproportionately affects B40 lorry drivers whose income is tied to cargo weight [5]. On public safety and disaster preparedness, following a series of minor earthquakes in Johor in September 2025, Ng called for clear protocols, transparent communication, and visible action plans from the government, and pressed for assessments of hospital capacity to handle casualty surges [5]. She expressed concern about what she characterised as vague and non-committal responses from senior government officials during a dialogue in Segamat [6]. Her stated positions reflect an emphasis on community-level economic resilience and institutional accountability in public safety.
