NBS chief executive Sam Swann handed over a cheque for SAT40,000 (US$15,800) to SASNOC President Patrick Fepulea'i after the organisations agreed to work together.
The SASNOC says the funds will support preparations for the Tokyo 2020 Olympics, Birmingham 2022 Commonwealth Games and Solomon Islands 2023 Pacific Games.
The money could also be used in advance of youth events.
Samoa sent eight athletes to the Rio 2016 Olympics, while the nation's sole medal at the Games came at Beijing 2008 via weightlifter Ele Opeloge.
