The 3rd South Pacific Mini Games were held at Nukuʻalofa in Tonga from 22 August to 1 September 1989, with 16 nations contesting six sports.
Tonga’s national stadium, the Teufaiva Sport Stadium, was built for the Games on the previous site of the agricultural showgrounds. The stadium, new Atele gymnasium, and tennis courts, were built or refurbished with the aid of Taiwan and France. The venues were eventually completed just in time for the games following some controversy in the preceding months with the construction alarmingly behind schedule. The stamps commemorate both the Mini Games and the inauguration of the National Sports Stadium.
