The reduction of British Forces from 1970 meant the closure of some of their schools and it was decided by the Australian and New Zealand Governments that Primary and Secondary Education should be provided for the services children of both countries in Singapore. 

In September, 1971, four ANZ Schools were opened:
ANZ High School Changi,  the former RAF Grammar School
ANZ Primary School Woodlands, the former Royal Navy School ANZ Primary School, Tengah ANZ Primary School, Selarang All schools flourished and provided a valuable service to the community both in their normal role and as centers for the night classes and public meetings. The schools were visited annually by inspectors and balanced education was being provided.   With the announcement of the withdrawal of Australian Forces, further changes in the education system were needed and in December, 1973, New Zealand announced that it would assume responsibility for the continuation fo educational services for NZ pupils and those Australian children remaining in theatre. It was decided that New Zealand would establish three schools, one each at Woodlands, Tengah and Seletar, to open on the commencement of the second term May 1974. Work commenced at Woodlands School in late December 1973 to prepare the necessary specialist and secondary classrooms in Blocks A to D, later in the first term 1974 work commenced at Seletar to prepare the building which had been used as a married quarters ex-change shop for occupation at a school. 

The four ANZ Schools closed on 10th May 1974, after having been operating for 2 years and nine months, and the majority of equipment was moved during the vacation.
In May, 1974, three New Zealand Services Schools opened: NZ Services School Woodlands NZ Services School Tengah NZ Services School Seletar 
With the final withdrawal of British Forces during 1975 and the re-location of NZ families at Tengah, Nee Soon and Woodlands, further changes to the education system followed. On the 19th of December 1975 seletar School was closed and from February 1976 all children attended either Woodlands or Tengah Schools thus saving a great deal of travelling time.   In 1980 the Primary School in Tengah was closed down, leaving Woodlands as the only Primary and High School for NZ Force South East Asia dependants and the school was now known as
NZ Force School, Sembawang
NZ Force South East Asia remained in theatre until 1989 when the doors to the school known as NZ Services School, Woodlands and NZ Force School, Sembawang closed for the last time. This was the end of the Australian, New Zealand and United Kingdom's long occupation of Singapore.
