Schaafhausen, who was known as “The Iron Lady, passed at her home in New Zealand over the weekend.
She was 83 years old.
The late Schaafhausen helped Samoa win its first Hong Kong Sevens title in 1993.
The Chairman of Moata'a Rugby and former Manu Samoa star and sevens player, Falepauga Filipo Saena, said Schaafhausen was the mother figure of the rugby community.
"That's exactly how she will be remembered," he said.
