RNZ reports the sport was introduced into the country last year after the Oceania Fencing Confederation gauged interest in the Pacific region and sent a coach from Australia to teach the sport in local schools.
Samoa is the first Pacific Island country to try its hand at the Olympic discipline.
National coach Tuiloma Walter Lee Imo said about 20 boys and girls initially took up the opportunity but only a month ago did the coach return and the top eight were selected to compete in this week's event.
