Naoupu has also played for the Ireland women's national rugby sevens team in the World Rugby Women's Sevens Series. In February 2017 Naoupu, together with Alison Miller and Hannah Tyrrell, was controversially withdrawn from Ireland's 2017 Women's Six Nations Championship squad in order to represent the Ireland Sevens in the 2017 USA Women's Sevens. This was because Ireland's Sevens were chasing a top eight finish in the 2016–17 World Rugby Women's Sevens Series in order to qualify for the 2018 Rugby World Cup Sevens. In April 2017 Naoupu scored three tries as she helped Ireland win the Challenge Trophy at the 2017 Japan Women's Sevens.
