Sayampanathan, the Ritachuan Corps, Jurong Town Corps and Golden Mile Corps were combined to form the Jurong Area on 1st January 1978. On 1st September 1978, there was a major restructuring of the St John Ambulance Brigade, Singapore where the initial Corps were dissolved and the Five Areas were reshufled and formed four Districts (A, B, C and D) and within the Districts were divided to ten Areas
(1 to 10). Under the leadership of Mr Lee Kok Hui and his group of dedicated officers, Area Nine progressed rapidly in the 1980s and became one of the premier Areas in the Brigade. In 1990, Mr Lee Kok Hui was promoted to the National Headquarters as the Chief Cadet Officer. Mr Chua Wee Kwang took over as the Area Commissioner while Mr Goh Kiah Tian was promoted to Area Superintendent. In 1996, another major change in the structure of the St John Ambulance Brigade in Singapore took place. The District level was removed. Areas were restructured and renamed as Zone and came under the direct command of the National Headquarters. Training Centres (or Divisions) were renamed as Corps. With the new structure, Zone Nine continued their excellent service such as public duty, annual blood donations and senior citizen gatherings.
